Question

functions of cell wall

Answer 1

The cell wall gives the plant its actual shape. It acts as a gatekeeper, because it determines what can come in and out of the cell in order to keep the cell protected. It is kind of like the outside bricks of a castle, only, as you will learn as you read on, there are holes throughout this castle. Those holes do make the cell vulnerable, but they are important to the function of the cell.

A plant cell has a cell wall, whereas an animal cell only has a cell membrane.



A redwood tree and a dandelion both have cell walls on the outside of all of their cells. The cell walls are there to give the plants their shape and support; however, the cell walls act and are constructed a little different to meet the needs of the particular plant. For instance, a 100-foot redwood tree needs a very strong and rigid plant cell wall so that it can grow to its great height and not fall over in the wind. On the other hand, a little yellow dandelion out in the field needs to have more plasticity so that it can bend, not break, as the wind blows through the field.
