Kidney leafy and floral, their location on the stem.

The stem is part of a plant connecting among themselves the main nutrition authorities-kin and leaves.

Stem with leaves or kidneys located on it are called escape. Each Escape develops from the kidneys. Remember: leaves can be located alternately, oppositely and mutter. The places where the leaves are located are called nodes, and the sections between the two closest nodes are called interstices.

There are elongated shoots with long interstices and shortened - with short interstices and pinned nodes.

The angle between the sheet and the intercourse layer above is the name of the leaf sinus.

At the top of the escape there is usually the top kidney, and in the sinuses of the leaves - stubborn, or side, kidneys.

Studying seed germination, you watched the development of a seed germinal kidney escape

beans. How does the escape from the kidney, located on the stem? Consider the shoot of a poplar or an apple tree. At the top of these shoots is located on one top kidney. On the sides of each branch in those places where the leaves were, side kidneys are located.

Side kidneys are located on the stem as the leaves. On the branches of the poplar and apple tree kidneys are located one, each other. This location is called another. Another kidney location has many trees and shrubs: cherry, birch, cherry, hazel and others.

If we look at the shoots of lilac, elder, jasmine, honeysuckle or indoor plant Fuchsia, we will see a completely different placement of the kidneys. They are located two, one against the other - contrary. Let's see what buildings have kidneys.

The kidney is covered with dense leathery flakes protecting it from rain, wind and others unfavorable conditions.

Sold with escape one of the kidneys and consider it with a magnifying glass. Under the scales, the rebound stem, located in the very center of the kidney, and small, wrinkled embossed leaves are noticeable. In the sinuses of these leaves there are embossed kidneys, similar to grains, barely noticeable even in a magnifying glass. Thus, the kidney is a successful escape.

If you cut several kidneys, you can see that inside the inclusive leaves are located inside around the stuffy escape. Such kidneys are called vegetative or leafy. Inside other kidneys are noticeable incharging buds. This is floral kidneys.

Flower kidney in appearance You can distinguish from vegetative. They are larger than vegetative and have a rounded shape.

By location on the shoots of the kidneys, their shape, size, color, chopping and for some other features characteristic of each type of plant, you can determine the name of the tree or shrub even in winter.

When recognizing trees and shrubs in winter, pay attention to the following signs characteristic of kidney.

The kidneys are usually located right on the stem. An exception is alder. Olhi, they are sitting on special legs, and on this basis, as well as in earrings and small bumps, it is easy to distinguish from other trees. The poplar will learn from his sticky resinous pointed kidneys who have a peculiar pleasant smell. The kidney willows are covered with only one scales resembling cap. There are no renal scales in the crash. The oblong major kidneys rowan are pubes and therefore well distinguishable from the kidneys of other trees.

Kidney cherry and black currant possess a pleasant fragrant smell. A contrary kidney elderly, on the contrary, the smell is unpleasant. Slowing them, you immediately distinguish the elder from other shrubs.

The stem is part of the plant connecting among themselves the main nutrition authorities - root and leaves.

The stem with the leaves or kidneys located on it Escape. Each Escape develops from the kidneys. Remember: leaves can be located alternately, oppositely and mutter. Places where leaves are located, callednodes And the sections between the two nearest nodes call interstices.

There are elongated shoots with long interstices and shortened - with short interstices and pinned nodes.

The angle between the sheet and the above-items lying above is called Obsolete sheet.

On the top of the escape is usually Top kidney, and in the sinuses of the leaves - stuffed, or side, kidneys.

Studying seed germination, you watched the development of a seed germinal kidney escape

beans. How does the escape from the kidney, located on the stem? Consider the shoot of a poplar or an apple tree. At the top of these shoots is located on one top kidney. On the sides of each branch in those places where the leaves were, side kidneys are located.

Side kidneys are located on the stem as the leaves. On the branches of the poplar and apple tree kidneys are located one, each other. This location is called next. Another kidney location has many trees and shrubs: cherry, birch, cherry, hazel and others.

If we look at the shoots of lilac, elderberry, jasmine, honeysuckle or indoor plant of Fuchsia, we will see a completely different placement of the kidneys. They are two, one against the other -contrary. Let's see what buildings have kidneys.

If you cut several kidneys, you can see that inside the inclusive leaves are located inside around the stuffy escape. Such kidneys are called Vegetative or leafy. Inside other kidneys are noticeable incharging buds. it Floral kidneys.

Flower kidneys in appearance can be distinguished from vegetative. They are larger than vegetative and have a rounded shape.

By location on the shoots of the kidneys, their shape, size, color, chopping and in some other features characteristic of everyoneplant type, you can define the name of the tree or shrub even in winter.

When recognizing trees and shrubs in winter, pay attention to the following signs characteristic of kidney.

The kidneys are usually located right on the stem. An exception is alder. Olhi, they are sitting on special legs, and on this basis, as well as in earrings and small bumps, it is easy to distinguish from other trees. The poplar will learn from his sticky resinous pointed kidneys who have a peculiar pleasant smell. The kidney willows are covered with only one scales resembling cap. There are no renal scales in the crash. The oblong major kidneys rowan are pubes and therefore well distinguishable from the kidneys of other trees.

In the germination of seed, Escape is developing from the renings of the nucleus of the seed. W. perennial plants Break gives the beginning of the kidney. The kidney is a successful escape. It consists of a shortened stem with closerly close-limited leaves. At the top of the stem is a cone an increase in the educational fabric. Due to the division of the cell cone cells, the size of the stem in length, the formation of leaves and external kidneys occurs. Outside the kidney is protected by renal scales, which are modified lower escape leaves. By location on the shoot of the kidneys are the top and side.

Top kidney

- This is a kidney at the top of escape, the rest of the kidneys - side. They are divided into stool and apparent.

Grocery kidneys

Regularly arise in the sinuses of young sheets near the top of the maternal escape. Their location accurately corresponds to the list. Therefore, in winter, the kidney can determine the location of the leaves.

Side kidneys

which develop out the sinuses on interstice, roots and leaves, are called Podcants. They often provide vegetative reproduction of plants. Puttingular kidneys on the leaves immediately develop into small rapts with apparent roots, which fall out of the sheet of the parent plant and grow into new individuals. These kidneys are called brood (Briefillium, Rosyanka). They can occur in the sinus of the sheet and modify in the bulWhis (Lily Tiger) and the Nuberki (hustling hustling).

The kidneys on the structure is not the same. Most plants are closed (protected), because Outside, have kidney scales glued with resin (in coniferous), other adhesive adhesives (poplar), some are often omitted. There are plants with open (unprotected, bare) kidneys. They are deprived of renal scales (Kalina, Crush).

According to the inner structure, the following types of kidneys are distinguished:

1) Vegetative - consist of a stuffed stem, scales, ridiculous leaves and an increase in increasing cone;
2) generative - floral, consist of a stuffed stem, scales and fasteners of a flower or inflorescence (red elder);
3) Mixed - consist of a stuffed stem, scales, embossed leaves and flower and inflorescence (apple tree, spiroia).
Generative and mixed kidneys are larger and more rounded than vegetative.

Kidneys who are at rest (autumn - winter), and then unfold and give new shoots, called by wintering or kidney resumption. Beyond their scores there are growing shoots.

Sleeping kidney

- They are within a number of years at rest. The stimulus for their awakening is damage to the trunk.
