A plant's cell wall is made of cellulose fibers. What is the purpose of a plant's cell wall?

Answer 1

To support the shape of the plant

Since plants lack backbones and bones, unlike some animals, they will fall over if they don't have either. This is where the cell wall comes in; it's a thick wall that supports the shape of the plant and allows it to stand without falling over.

Another role is to function as a semi-permeable membrane, allowing water to enter the plant for use and enabling the plant to experience turgor pressure, which causes the cell wall to press against the plant when the plant absorbs water, causing the plant to become turgid.
