Question

Why plant cell needs a cell wall? I am giving 40 points for the answer

Answer 1

Cell wall provides protection, shape and rigidity to a plant cell.

Plant cells are actively involved in water transportation, and thus plant cell wall ensures that the cell does not burst due to over expansion as water flows in (internal turgor pressure).

Besides this cell walls also provides structural and mechanical support, protection against pathogens and dehydration.
