The difference between Plasma Membrane and Cell Wall is that the former is present in plants and animals, while the latter is present only in plants and fungal cells. The plasma membrane is also known as the cell membrane. It helps to separate the interior of the cell from the outside environment. The cell wall acts as the covering outside the cell membrane to protect it. It provides protection and structural support to the plants.

Difference between Plasma Membrane and Cell Wall

The cytoplasm of the cells is surrounded by the plasma membrane, which separates the cell’s interior from the external environment. In contrast, the cell wall is a non-living trait seen only in the plant cell, that protects the protoplasm. Below are the four differences between Plasma Membrane and Cell Wall:

Plasma membrane Cell wall
It is semi-permeable and allows easy movement to specific components. It is a rigid structure and completely permeable. Does not allow any movement of most molecules.
The plasma membrane is made up of lipoproteins and phospholipids. The cell wall is made out of cellulose and pectin.
The plasma membrane helps to transport nutrients into the cell and toxic substances out of the cell. It regulates intercellular transport and serves as a food reservoir.
It is a flexible lipid bilayer that allows animal cells to change their structure into different forms. The cell wall renders mechanical strength and protects against pathogens.


Write four differences between the plasma membrane and cell wall

The four difference between the plasma membrane and the cell wall is that the plasma membrane allows animal cells to change their structures into various forms. The cell wall, on the other hand, helps the plants stay rigid due to the presence of a cell wall.
