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.
The following are the comparison between a cell wall and a cell membrane:
• The cell wall is found only in plants, while the cell membrane is present in all kinds of cells.
• The cell wall is the most outer covering of a plant cell, while the cell membrane is the outermost layer of an animal cell.
• The thickness of the cell wall is about 0.1 um, while the thickness of the cell membrane is 7.5 to 10 nm.
• The cell wall is thick and rigid, while the cell membrane is thin and delicate.
• The cell wall protects the cell from outside, while the cell membrane protects the cell internally.
• The cell wall is metabolically inactive, while the cell membrane is metabolically active.
• The cell wall grows in thickness, while the cell membrane remains static.
• The cell wall is completely permeable, while the cell membrane is selectively permeable.
Thus, the cell wall is the outer layer of the cell and is the covering outside of the cell membrane.
