Cell Wall (Plant, Fungal, Bacterial)- Structure and Functions
- 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 which 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-lipid-polysaccharide complexes.
- The cell wall has many important functions in a cell including protection, structure, and support.
