Question

What is cell wall and it functions?

Answer 1

Answer:

The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the cell wall.

Answer 2

Answer:-

A cell wall is a structural layer surrounding some types of cells, just outside the cell membrane. It can be tough, flexible, and sometimes rigid. It provides the cell with both structural support and protection, and also acts as a filtering mechanism.

The functions of cell wall are:-

•    It provides protection to the cell and prevents from any physical damage.

•    It provides structure to the cell.

•    It prevents from osmotic bursting.

•    It protects the protoplasm against mechanical injury.

•    It controls intercellular transport.
