Question

why plant cell need cell walls​

Answer 1

Plant cells need cell wall so that mechanical support, tensile strength and protection be provided to a plant.

Cell wall

• In the field of science, a cell wall can be described as the outer most covering of a plant cell. Plant cell wall is non-permeable.
• The plant cell walls provides support to the cell and helps in maintaining its shape.
• A plant cell wall reduces osmotic strength by avoiding water to be lost from it.

Answer 2

Explanation:

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.
