Awesome world: what protects the plant cell from the outside?

From this article you will learn what protects the plant cell from the outside. We will also consider the general structure of the plant cell, which will further expand your horizons. So, what protects the plant cell from the outside? 3 grade general education must necessarily explain it to children.

This issue is very important, elementary school children should already understand that everything in our world consists of different cells. They have different structure and functions. The cell can only be seen with a microscope, so small it is in its size. But there are also smaller components, which are called organoids. Let's begin our cognitive story.

Plant cell: structure

So, we have already found out that the cell is a part of the constructor of all living our planet. We did not just fall from the sky, but for a long time evolved from unicellular creatures. So the cell is the result of the evolution of living matter. The organism can contain a different number of them - from 1 to several billion. So it becomes clear that the cell can exist as a separate organism and perform all the necessary functions.

To begin with, it protects the plant cell from the outside. Each cell is covered with a kind of wall called a cell membrane. It is not everywhere the same thickness, in some places there are pores, with the help of which it becomes possible the exchange of substances between the cells. So, what protects the plant cell from the outside, we found out.

Inside are:

  • protoplast;
  • Derivatives.

The main difference between these substances is that the protoplast is a living substance, and its derivatives are not. Protoplast, in turn, is formed from the following components:

  • cytoplasm;
  • core.

On the question of what protects the plant cell from the outside, we have already received the answer, now it remains to consider the structure and functions of the cell wall.

Cell Wall

When comparing the plant and animal cells, note that the wall that bounds the cell can only be in plants. It has a fairly solid structure, as it performs some very important functions, which we will discuss in the next section. One of the functions we already mentioned in the table of contents of the article: what protects the plant cell from the outside. Basically it consists of cellulose. Also there are cells that do not have this shell, they got the name - protoplast.

What else is important to distinguish in the structure of the walls? Of course, the presence of pores. Pores are depressions for interaction and metabolism between neighboring cells.

Functions

The last issue of our work is the allocation of all the functions that the protective wall performs in plant cells. We propose to list them in the form of a list:

  • Mechanical strength;
  • support;
  • Resistance to stretching and proliferation;
  • Growth regulation;
  • Shape regulation;
  • Conductor of water and minerals;
  • Prevention of water loss;
  • Restriction of cells from penetration of bad bacteria;
  • Transportation of substances;
  • Stock hemicellulose;
  • Cation stock.

As you can see, the role of the walls is quite large.
