What is the difference between the plasma membrane and cell wall? Give the functions of each.
| Plasma membrane | Cell wall |
| Its is living. | It is non-living |
| Found in all the cells | Found in plant cells, bacteria, and fungi. Absent in animal cells. |
| Selectively permeable | Freely permeable. |
Functions of Plasma Membrane :
(i) It gives shape and rigidity to the cell.
(ii) It helps in maintaining the chemical composition of the cell.
(iii) It helps in cellular movement or locomotion as in amoeba.
Functions of Cell Wall :
(i) It provides support to a plant cell.
(ii) It determines the shape of the cell and prevents it from drying.
The power house of cells is called :
Cell wall
Mitochondria
Ribosomes
Nucleus
