Cell wall: The cell wall is a rigid

The cell wall is a rigid and protective layer around the plasma membrane which provides mechanical support to the cell . It is a non-living structure that is formed by the living protoplast. Animal cells do not have a cell wall . They are present in most plant cells, fungi, bacteria, algae, and some archaea. In-plant cells, the cell wall is made up of cellulose, hemicellulose, pectin, and protein. In many fungi, the cell wall is formed of chitin and in bacteria, the cell wall contains protein ... The cell wall is an additional layer of protection on top of the cell membrane. You can find cell walls in both prokaryotes and eukaryotes, and they are most common in plants, algae, fungi and bacteria. However, animals and protozoans do not have this type of structure. Cell walls tend to be rigid structures that help maintain the shape of the cell . Learn about the cell wall , a structural layer that surrounds some cell types, found outside the cell membrane. Discover its composition, properties, roles and how it varies across different organisms and cell types. Cell wall, specialized form of extracellular matrix that surrounds every cell of a plant . The cell wall distinguishes plant cells from animal cells and provides physical support and protection.
