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

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.

Similarities: Both plasma membranes and cell walls protect the cell, both are selectively permeable and allow certain substances to enter and exit, both provide structural support

Differences: Cell walls are usually only found in bacteria and plants, organisms with cell walls also contain a plasma membrane, the plasma membrane is much more flexible, the plasma membrane is made of a phospholipid bilayer
