Question

Write the functions of Cell wall ?​

Answer 1

Answer:

A major role of the cell wall is to form a framework for the cell to prevent over expansion. Cellulose fibers, structural proteins, and other polysaccharides help to maintain the shape and form of the cell. Additional functions of the cell wall include:

Support →→ The cell wall provides mechanical strength and support. It also controls the direction of cell growth.

Withstand Turgor pressure : Turgor pressure is the force exerted against the cell wall as the contents of the cell push the plasma membrane against the cell wall. This pressure helps a plant to remain rigid and erect, but can also cause a cell to rupture....

i) The cell wall protects the cell against any physical damage and invading pathogen (disease causing germs).

ii) It regulates and control the direction of cell growth.

iii) It provides strength, structural support and maintain the shape of the cell.

iv) It act as a selectively permeable membrane by allowing the entry of small molecules to pass through it.

v) It also act as a storage unit and helps in storing carbohydrates, used for plant growth.

$\fbox{Cell wall }$

➸ It is outer non- living part of the cell but not a organelle.

➸ It is made up of pectin, lignin, cellulose, glycolipids.

➸ Its thickness is 20-80nm, and provides a rigid structure.

➸ It protects the cell from external environment.
