Question

what is the use of rigidity of plant cells

Answer 1

the rigidity of plant cell is due to the outer cell wall. this rigidity or hardness helps the cell to withstand the force due to osmosis. an animal cell would burst whereas the cell wall exerts an equeal amount of force and prevents the cell from exploding

Answer 2

"The strongest component of the cell wall is a carbohydrate called cellulose,a polymer of glucose.T he cell wall gives rigidity and strength of the plant cells which offers protection against mechanical stress...The rigidity of primary plant tissues is due to turgor pressure and not from rigid cell wall."
