Question

In the text area below compare and contrast a cell membrane and cell wall.

Answer 1

Cell membranes allow certain objects in and out, and are generally less solid than cell walls, which are hard and thick and let nothing through. Cell walls are found in plants normally, while membranes are found in animals.

Answer 2

A cell membrane, seen in plant and animal cells, is selectively permeable and made of a phospholipid bilayer.

The cell membrane and cell wall control what enters and leaves the cell.

The cell wall is seen in a plant cell, gives shape to the cell, and stores carbohydrates.

The cell wall is selectively permeable and made of cellulose, which causes plants to have a rigid structure.
