Question

What is cell wall ??????? ​

Answer 1

The cell wall is the protective, semi-permeable outer layer of a plant cell. A major function of the cell wall is to give the cell strength and structure, and to filter molecules that pass in and out of the cell. A cell is the smallest part of an organism that still contains that organism's elements.

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.
