Plants are one of the most numerous and varied in the forms of the kingdoms of wildlife. They give all living beings the opportunity to breathe clean air, producing oxygen in the process of photosynthesis. Provide people and many animals with food and useful substances, decorate our life and make it beautiful. One of the most diverse departments of this wonderful kingdom are about them and talk on.

Covenate: Classification

This department includes two huge class in its composition:

• monocycle;
• dichomotic.

Each of them is valuable not only for nature as a whole, but also for people especially. After all, it is worth only to call at least several representatives who have one-bedroom and examples in their composition will immediately confirm their enormous practical role in a person's life. So, they include:

• rye, wheat, oats, rice, buckwheat;
• rosehip, potatoes, tomatoes, eggplants and other cultures;
• a huge number of medicinal herbs.

In general, the variety of coated bridges is calculated by hundreds of thousands (about 350,000). At the same time, one-bedroom, and dysotic plants, examples of which can be given for a very long time, have their own characteristics in the structure, lifestyle, life processes. We will look at one of the classes - Dwallery. We will understand what characteristics these plants have, which include their meaning.

Favoric Plants Class Family

Classification can be different. There are several options:

• takhtajian system;
• rIVIL system;
• Dalgren and Thorn;
• Kronkin.

Everyone took on the basis of certain signs and shared the whole class on orders of magnitude, family or subclasses. For ordinary people more familiar with school bench such a taxonomic unit as a family. Therefore, these are the most common and numerous groups that are part of the class under consideration.

1. Motomy, or legumes. What plants are bombing here? For example: peas clover, peanuts, rank, acacia, astragal, nut, ceratonia and others.
2. Rose colored. Examples: Rosehip, apple tree, pear, plum, strawberries, raspberries and others.
3. Cruciferous, or cabbage. Typical representative - cabbage. An example of which can still be attributed to this family - radish. And also: Mustard, Freard, Opechaig, just about 3 thousand species.
4. Composition - include in their composition a large number of weed, medicinal, fodder and food plants. Representatives: Chamomile, Dandelion, Astra, Vasilek, Sunflower and others.
5. Polenic. A dietary plant, an example of which can be brought here - tomato. And with it, most of the important vegetable crops cultivated by a person (potatoes, eggplant and others). The same family includes very poisonous belladonna.

Less known for our country are such families as:

• Laurels;
• Tolstanka;
• Portulakoe;
• Grape;
• Mirty;
• Pumpkin;
• Begonia;
• Nut;
• Yves;
• Umbrella;
• Birch and others.

In fact, there are quite a lot of them, so it is difficult to list everything. Consider now what common features All representatives of the bipathicians possess.

Features of the structure of dwoom

Like all higher plants, they have stem, leaves, root, flower. If we are talking about woody forms, that is, the trunk and branches. In general, the structure of the bipathic plant is no different from any other. However, there are also its own characteristics that make it necessary to attract certain species to this class.

These characteristic data are their distinctive feature from one-bedroom, because all the flowering in the main parts are similar, it is difficult to correctly relate to taxa species, if you do not know special signs.

Basic signs

So, these are the following parameters:

1. In most cases, mesh.
2. Root system - rod, most often long-term.
3. Flower structure formula: h 4 l 4 t 2 + 4 p 1. In general, the number of parts should be multiple or 4 or 5.
4. A layer of Cambia is located between xylem and the Floem, so many forms have a decisive stem.
5. Sheet plate often strongly dissected.

These signs of dicotyledonous plants do not speak at all about the fact that all representatives are arranged only, and not otherwise. As everywhere, there are also exceptions here, some combinations.

However, the most important feature is that the seeds of dietary plants have two semilaries, located against each other. On the example of peanut or beans, this can clearly consider the naked eye. This feature is characteristic of everyone without the exception of representatives of dwoom. It was for him that they received their name.

Double plants: examples, photo

We have already given a lot of examples of various representatives of this class. However, mostly stopped only on those species that grow in our country. Below you can see photos of some foreign endemics, which climatic conditions Russia is not at all suitable. This, for example:

• laurel;
• delonix Royal;
• sundew;
• sarration;
• non-tent;
• black and red tree and others.

The photo shows that they all have beautifully and brightly colored whites. In general, almost all the disadvantages have spectacular flowers. However, there are exceptions among weed herbs.

Interesting magnolias. Each species is a dysdootilic plant. An example of a representative of this family - Magnolia star. Very beautiful and fragrant plant of the East. It is consistent with unusual and romantic legends. Magnolias are part of the culture of many southern countries.

Spicy plants

Representatives of the most fragile, fragrant species are also spicy. For example, such as:

• cinnamine;
• laurel;
• coriander;
• caraway;
• anise;
• dill;
• parsley;
• easy pepper and others.

Of course, their role in the food industry is great. After all, in addition to direct destination - improve the taste of the dishes prepared and give them a special flavor, they are still used both as dosage forms.

Umbrella

Class Divorny plants include in its composition such a family as umbrella, or celery. Their main distinctive feature is a characteristic inflorescence in the form of an umbrella. Small collected in beams of flowers pale, rarely bright coloring. However, that they really highlight are the smell. All representatives contain a large number of essential oils, tanning substances, alkaloids. Therefore, the aroma of umbrellas is spread far in the area in the place where they grow.

Representatives are as follows:

• coriander;
• carrot;
• azhgon;
• celery;
• fennel;
• parsnip;
• boligols;
• borshevik;
• water;
• astranition;
• feverweed;
• dish and others.

There are both poisonous and very useful plants for humans. Also, many are decorative.

Rosicular

The most popular representative is a rose rose or rose. This is a dysotic plant, the example of which always leads, barely comes to talking about but, of course, not only it is part of this tasty taxon. Why tasty? Because it is here here:

• raspberries;
• cherry;
• plum;
• quince;
• fig;
• apple tree;
• irga;
• rowan;
• apricot;
• sweet cherry;
• almonds and other very appetizing representatives.

In addition to taste, they are also valuable vitamins, useful macro and microelements and various compounds.

There are among representatives and ordinary herbaceous forms: typical, nettle, cannabis, gravel and others.

Composition

This family includes grassy, \u200b\u200brarely rustic perennial plants. There are so many representatives that they are found almost all over the globe. Composition is also in the tropics, and in the Arctic. This is the most numerous and diverse group of all dicatular.

Examples can be given hundreds. Let's call the most famous to become clear what particular plants are we talking about:

• aster;
• sunflower;
• dandelion;
• dahlia;
• chicory;
• marigold;
• chamomile;
• daisy;
• serpuha;
• ambrosia and others.

The most interesting representatives are:

• blind's scalies;
• brachylene Merana.

They are interesting in that they are very powerful trees tall up to 20/40 meters, respectively. Skalzia has very fragrant yellow flowers collected on the tops of the branches. Many such trees form whole forests in the Galapagos Islands.

Brachylene Meran grows in South Africa and Madagascar. Up to 40 meters high. Flowers are very large, collected in panicles on the tops of the branches.

Detailed decision Paragraph § 16 by biology School 2100 for grade 6 students, authors Lovyagin S.N., Vakhrushev A.A., Rautian A.S. 2015.

• GDZ test papers on biology for grade 6 can be found

Question 1. Do you agree with the explanation of the biologist? What other arguments can you bring? Yes, I agree (-I). It is very important to be able to distinguish and know those or other plants. Even near some plants, it is dangerous - Borschevik Sosnovsky - when contacting with skin, a strong burn occurs with a skin.

The reason for discussion what problem can the Dialogue of the Antoshki and the biologist? Compare your version with the author (p. 141). What are the signs and why distinguish plants?

Question 2. What is the view? (5th grade)

The view is the historically established set of populations, the individuals of which are similar in the morphological, physiological and biochemical features, are adapted to certain living conditions and occupy a certain area in nature - the area, as well as are able to cross each other with the formation of fruit offspring.

What is a sign? (Life experience)

The sign is an indicator, sign, a sign for which you can find out, determine something.

What form are leafy plates? (§ 11-12)

The form sheet plate Determined by the ratio of length and width and by what part of the plate it accounts for its largest width. There is a rounded, oval and oblong; Broad-way, egg-shaped and lanceal; Armchair-like, conversely and frantic and frantic. Linear. In addition to these ten basic forms, some non-standard types of leaves are distinguished, which do not fit into the above classification of sheet plates on the ratio of length and width. Among the baked plants is the leaves of scaly (Western Thuja), needle (spruce, pines, juniper), heart-shaped (linden), rhombic (bearded abandon) and triangular (gently sweet-bitter, currant).

On the form of the top plate, the sheet may be: stupid (1), acute (2), pointed (3), pointed (4), leaked (5).

The base of the sheet of sheet is: wedge-shaped (6), rounded (7), heart-shaped (8), sweatshop (9), spear (10), unequal (11), cut (truncated) (12) and narrowed (13).

On the shape of the edge of the plate distinguish the leaves: Open-Running (1); gear when both sides of the teeth are equal to (2); Pilly, when one side of the teeth is longer than the other (3); Golden - with rounded teeth (4); Loved (5); Wavy (6). If the teeth of different sizes are distinguished by the leaves of dual-ray (7) and bicopylene (8).

What is Sejdol? (§ five)

Sejdoli - the first leaves of the embryo that may contain a stock nutrients.

What kind of forms do you know? (§ 11-12)

The types of leaf housing are arc, parallel, mesh (or peristole), palpat.

What systematic groups are you known? (5th grade)

Similar species are combined into childbirth, childbirth - in the family, family - in orders (in animals - detachments), orders in classes, classes - in the departments (in animals - types), departments in the kingdom.

Question 3. Choose the most convenient feature for distinguishing bipartal and monocotyledonic plants.

One characteristic is not enough to distinguish bipathic and monocotyledonic plants.

Answer

© DV Pozdnyakov, 2009-2019

We live in vegetable world Nature, where harmony and beauty reigns. We are amazed by the diversity of trees, herbs, flowers on our planet. The entire plant world scientists of botany and biologists were divided into types, departments, classes, detachments, families, childbirth, species. Such a systematics makes it possible to better understand the diversity of plants and systematize the knowledge of each vegetable subject. Consider the basic concepts in the world of plants - the classes of dietary and monocotyledonic plants, features, differences, distribution on the globe and their role in our lives.

The plant of plants relating to the coated brine or flower consists of two significant classes: Dichomotic and Monocoan. The class of dietary plants includes a numerous variety of plant specimens that appeared on our planet for a long time. Dicotomic in quantitative ratio is much higher than one-bedroom plants.

On the globe there are more than 300 families of dietary plants and about 180 thousand their species. IN former USSR There are approximately 15 thousand species of plants belonging to this class. Dicotomic arose on the planet much earlier than one-plan. It has been proven that the latter occurred from dicotyard after a long time. We list the main signs on which plants can be attributed to the class of dicotyledan representatives.

Two seeds in seed - One of the main indicators of the plant belonging to the class of dwoom. A nutritional supply for the development of a future tree, a grassy or flowering plant is located in a seed seed embryo, either in the cloth surrounding the embryo - endosperm.

Rod root The system is formed from the germs of the seed root. It consists of the main root and more subtle - side and apparent roots. Such a strong underground part reliably holds the plant in the ground, ensuring the suction of the necessary nutrients and moisture, so necessary for the vital activity of the plant.

Palchaty and Curious jilking Sheet plate is another feature of the plants of the class of dietary. The edge of the sheet may have Whole structure, so I. rated. Divorce plants can be found with simple and complex leaveshaving several simple leaves on one hand.

Channels stem Bicycle plants have a ring structure with a layer cambiawhich allows the stems or trunks to grow into width and attach a powerful plant structure. The stalk is transported by organic and mineral components. The trunk and stem create depot of nutrients and water throughout life cycle plants. On the stems and branches of the double-dollar leaves are arranged ordered.

Four-five-colored flowermore often S. Double perianth Characterized for dicatoral. Fallen bombing plants are pollinated by insects.

All vegetable life types (From herbal to woody) inherent in this class.

What signs are characteristic of monocotional plants

One-barrel class It was formed much later than two collapsion and is not so numerically in the plant world. One-bedroom includes about 80 families and a little more than 60 thousand species of plants. There are signs that characterize single-bedroom plant representatives.

Germ with one cotyadal - The main indicator of the difference of the class. The depot of nutrients is located in a nearby space - endosperm or sparkling fabric.

Urocheted root The system is characteristic of monocoons. The embryonic root of this class is weakly formed, so in an adult plant forms a variety of apparent roots forming the urine formation of roots.

Parallel and Arc jilking Sheet plates are another characteristic feature feature. Leafy Cherces usually not developed, and are formed in the form of a vaginal termination, covering the stalks of plants. Leaves Monocotional plants - simple with a smooth edge.

Conductive stem fabric formed by separate beams Without a concentric growing layer of Cambia.

Three-colored flowers with a simple perianth - Another important sign of monocotional representatives. Flowers of this class of plants are mainly pollinated by the wind.

Herbate plants as Zlatkov and lukovichny Presented in the life plant forms of monocotyledonic plants.

Table One-Oedasic and Divorce Plants Grade 6

This table clearly demonstrates the main distinguishing features of the two large plants classes: dicotyled and monocoons.

Differences of monocyan and dicaric plants

Recall the differences between the classes of monocotyled and dietary plants:

1. Semen: At the class of monocotional representatives, the seed contains one of the seedlings, two semi-siardolis have two semi-colors.
2. Root systemsa: Urochkah - in one-bedroom and developed rod root from dicotomy.
3. Residential leaves: parallel and arcomes in monocoons, mesh and filament have dysotic plants.
4. Flower structure: Odnochlennaya - Petals Three-heeded with a simple perianth, diototal - four-five-year-old flowers with a double perianth.
5. Life form: The prevailing wood and grassy in two-bedroom and grassy in one-bedroom.
6. Pollination of flower: Mostly by the wind - single-bedroom grassy plants and pollination in the insects - in disadvantaged representatives.

Signs of single-bedroom and dicotyled coated plants

Covenate or Flower Green representatives of higher plants are distinguished by a huge species diversity. Flower, as a breeding organ - distinctive feature These beautiful Flora representatives.

Scientists Botany and Biologists set a number of signs that characterize the belonging of a vegetation instance to dicatular or monocotal representatives in the field of flowering plants. There are many families with distinctive features of the root structure, stem, leaf plate, flowers, fruits and seeds. In the present period, scientists have identified more than 300 thousand plant species from the flowering department.

Signs of single-bedroom coated plants:

• one cotyledon;
• rod roots;
• parallel or arc housing;
• more often herbian life forms;
• the flower has a simple perianth with three-six floral petals.

Signs of dicotyled coated plants:

• two seeds in the seed;
• taproot;
• curly or mesh leaf housing;
• herbaceous or woody vitality;
• the flower has a complex structure with a double perianth and a four-five-layer whisk.

Comparative characteristics of single-bedroom and dicotyledonous plants

The table is clearly represented characteristics Two classes of the kingdom of higher plants: dicotyledan and monocoons.

Apple tree - representative of the bombard wood plants. It is found in wild and cultural form everywhere, except for the northern latitudes. Fragrant apple gardens attract many insect pollinators.

And ripe fruits are one of the most delicious fruit deals. Apples are useful in fresh formSince they can accommodate a whole breeding of vitamins. Recycled fruits are used to obtain juices, compotes, jams, pastes. Decorative species Apple trees are decoration of our gardens and parks.

Fedrol plant root

The germ root of dysfotrol plants is strong and hardy. Subsequently, a strong powerful taproot. In case of subsequent growth of the plant develops a stable durable rod root system.

Singlean plant root

The root germs of monochetical representatives is poorly developed. During the growth of the plant, the main root does not gain strength and at some stage of development ceases to grow. But accumulate the power of the apparent and side roots, forming uriscouched root system. Hard roots firmly cover the surface fertile layer of soil and power supply and water supply of the plant.

Divorny plants in human activity

Falotian class plants represent an invaluable role in human vital activity. Let us list some of the main directions of using these plants.

• The floral world of dysfotical and other plants is "Light" land. Participation in photosynthesis leads to the improvement of our planet. In addition, many plants produce unique substances - phytoncides that can destroy many pathogenic microorganisms and viruses.
• Trees, shrubs, herbs, flowering plants adorn our environment. Many of them are good honey plants.
• Food qualities dicotyledonous plants allow a person to get delicious natural foodsaturated with vitamins, mineral components and vegetable fiber.

• Medicinal properties Plants have long been used by humanity in the cure of many diseases.
• Favoric representatives are used as feed For herbivores and.
• Construction and fuel production do not cost without use wood materials and woodworking waste.

Monocoor rod root system

The rod root is not characteristic of monocotyledonic plants. The video explains: what types of root system from dicotyledan and monocotal representatives and their roles in the life of plants.

Double rod root system

The class of dietary plants in the process of its formation has formed a steady powerful rod system of roots. Main taproot It is capable of reaching large soil depths in search of moisture and nutrition, showing strong resilience.

From the bottom of the stem often formed Putting rootswhich enhance the power of the root system, and in case of damage, disease or death of the main root - replace it and do not give the plant to die.

Side roots are born from the rod root, they are departed at an acute angle and distributed in the soil at a distance of 60-70 cm. Side roots are thin and play a greater conducting role in nutrition and water supply plants. Thus formed a rod root system of plants of the vocabulary.

Careful attitude towards the plants around our life, it is necessary to carry throughout their life. In addition to decorative and aesthetic value, Green Friends, thanks to photosynthesis, utilize carbon dioxide And enrich our planet with oxygen, give humanity a lot of food products, create a special world and harmony on Earth.

Why do you need plants, video:

Flora is accepted to divide on monocoa and dysdootilic plants, differing mainly by the structure of the embryo. Nevertheless, these classes of plants have other differences in the structure of vegetative and generative bodies.

Class of dismissal, or magnoliopsis: the structure of plants and their brief characteristics

To date, this class is considered quite large, as it includes about 200 thousand species. His representatives have a number of very characteristic distinctive features.

Divorny plants are represented by different forms - it is trees, bushes, and herbs. In rustic species inside the stem, there is a fairly powerful layer of Cambia - special fabric, which ensures its growth in width. Leaves of plants can be both simple and complex, but almost all kinds they are twisted - seating leaf plates are not characteristic of this class. The housing of the record in most cases is mesh. Mostly rod - has a primary, main root, from which side, small sizes grow.

Another feature is the structure of most species large flowers With bright color. They have a double periantole (cups and petals), flowers are predominantly five- or four-membered. Divorous plants are most often pollinated by insects.

And, of course, the structure of the embryo is very characteristic, which has two sidelines. By the way, it is with this feature that the name of the class is connected.

Divorny plants: the most common types

This class includes a huge amount of species that are included in several thousand genera and three hundred families. The most famous are the following.

The family of cruciferous - representatives of it are distributed mainly in the planet. Most of his species are herbaceous forms or small shrubs. Everyone knows such representatives of cruciferous as cabbage, radishes, horseradish, turnip, mustard and radish.

The Pink Family combines trees, shrubs and which are mainly common in a moderate or subtropical climate. For example, all known hips and decorative roses are treated just to this group. This includes most including apple trees, a pear, cherry, rowan, raspberry, cherry, blackberry.

Family legumes - its rustic forms and shrubs are distributed mainly in tropical and subtropical countries, and herbaceous prefer a more moderate and even cold climate. All representatives of the group are characterized by a specific wedge of the "moth" type. This group includes the following well-known plants: peas, beans, alfalfa, beans, soy. By the way, some species are actively involved in the nitrogen cycle.

Class a brief description of

This group is presented mainly. herbatous plants - Trees and shrubs in it are extremely rare. Their stalks, as a rule, do not contain Cambia and, therefore, are not capable of growing in thickness. Sheets are simple, with whole edges. They do not have a stuff and attach to the stalk of the edge plate, which is why they are called seating leaves. Residential in most cases parallel or arc.

Another feature is the urine root system in which there is no main root. In the embryo there is only one semilar, as evidenced by the name of the class.

Most of the monocotional plants are pollinated by wind. Therefore, their flowers are small, inhabitant, with a single perianth, mostly three-strange.

Typical representatives of this group are cereals: wheat, oats, corn, rice and others.
