Cellulose and pectin.
The main components of the cell wall of plant cells are cellulose and pectin. Cellulose and pectin are polysaccharide substances. The cell wall is involved in maintaining a certain morphology of the cell and enhancing the mechanical strength of the cell.
A thick wall that exists on the periphery of plant cells is what distinguishes it from animal cells.
One of the main features. [1] It is composed of three parts: the intercellular layer, the primary wall, and the secondary wall. The main components are polysaccharide substances. The cell wall is involved in maintaining a certain morphology of the cell, enhancing the mechanical strength of the cell, and is also related to the physiological activities of the cell.
After some plant cells stop growing, the cell wall layer that continues to accumulate on the inner side of the primary wall is located between the plasma membrane and the primary wall, which is called the secondary wall.
The cell wall is filled and attached with lignin.
It can increase the hardness of the cell wall and increase the mechanical force of the cell population, so the process of filling lignin is called lignification, and the changes that occur on the secondary wall are keratinization, embolization, mineralization, etc.

Anonymous users2024-02-02The chemical composition of the cell wall is that the intercellular layer is basically made up of pectin, and if the pectin in the plant tissue is broken down with pectinase, the cells will be discrete. The primary cell wall is composed of water, hemicellulose, pectin, cellulose, protein and lipids, and there is also a large amount of lignin in the secondary cell wall, which plays a protective role in plant cells.

Anonymous users2024-02-01Peptidoglycan is a macromolecular polymer found in the cell wall of prokaryotes, which is a multi-layer network macromolecular structure formed by the polymerization of acetylglucosamine, acetyl muramic acid and four or five amino acid short peptides. Peptide chains are attached to N-acetylmuramic acid, and peptide chains on different sugar chains are cross-linked to form stable water-insoluble products.
Difference Between Cell Membrane and Cell Wall:
1. Only plants, bacteria, and fungi have cell walls, while animal cells do not have cell walls. >>>More
The cell wall has changes, but its elasticity is worse than that of protoplasts, because it is composed of substances such as cellulose and pectin, so when there is a difference in the concentration of the inner and outer solutions, it does not change as much as the protoplast, so the plasma wall separation and recovery of the plasma wall is caused by the difference in the expansion and contraction ability of the two when they absorb water.
1. Maintain the shape of the cell, control the cell growth The cell wall increases the mechanical strength of the cell, and bears the turgoring pressure of the internal protoplasts due to the water absorption of vacuoles, so that the cell has a certain shape, which not only protects the protoplast, but also maintains the inherent morphology of organs and plants. In addition, the wall controls the growth of the cell because the premise for the cell to expand and elongate is for the cell wall to relax and irreversibly stretch. >>>More
The cell is the basic unit of structure and function of an organism. It is known that all living things except viruses are made up of cells, but viral life activities must also be in cells to be realized. Generally speaking, most microorganisms such as bacteria and protozoa are composed of a single cell, that is, a single-celled organism; Higher plants and higher animals are multicellular organisms. >>>More
