Question

7. "Plant cells have a cell wall in addition to the cell membrane." Give reason​

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:

The cell wall prevents the plant cells from bursting and helps to give the plant the structural support it needs; the "turgor pressure" caused by osmosis helps to give the plant rigidity and keep it upright.
