Write four differences between plasma membrane and cell wall.

By K Balaji|Updated : December 1st, 2022

The major difference between the plasma membrane and cell wall is that the former is present in both plants and animals while the latter is present only in plants and fungal cells. Plasma membrane is also known as 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.

Four differences between plasma membrane and cell wall

Given below are the four difference between plasma membrane and cell wall are mentioned.

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 to most molecules.

The plasma membrane is made up of lipoproteins and phospholipids.

Cell wall is made out of cellulose and pectin.

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.

Cell wall renders mechanical strength and provides protection against pathogens.

Summary:

Write four differences between the plasma membrane and cell wall

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