Cell wall is the structure that is not found in all cells, only in bacteria and plant cells where it is attached to the plasma membrane on the outer surface.
What is a cell wall?
A cell wall is a rigid structure that lies outside the plasma membrane and protects the contents of the cells of algae, fungi, plants, bacteria, and archaea.
Characteristics of a cell wall
- It can be a layer of chitin (in the case of fungi), cellulose (plants), peptidoglycan (bacteria), or other materials.
- It is responsible for protecting the contents of the cell and absolute rigidity to the cell structure.
Therefore, we can conclude that the cell wall is what covers prokaryotic cells and plant cells.
