Question

which statement is true about a cell wall but not a cell membrane?
it forms the outer layer of a cell
it gives an animal cell its shape.
it is selectively permeable.
it is made mostly of cellulose.

Explanation:

• Cell walls are made mostly of cellulose. Cell membranes are selectively permeable. Animal cells do not have cell walls, so the cell wall does not give an animal cell its shape. The cell membrane forms the outer layer of an animal cell, while the cell wall forms the outer layer of a plant cell (among other types).

Answer:

It is made mostly of cellulose.
