Animals and protozoa do not have cell walls
What are cell walls made of?
• Plant and Algae Cell Walls – cellulose
• Bacterial Cell Wall – peptidoglycan
• Fungi cell wall- chitin
• Archaea cell wall- isoprenyl ether
It’s Functions
• Helps maintain shape• Controls the rate and direction of cell
growth• Provides a defensive coat• Acts as a pressure vessel
Difference between the cell wall and cell membrane
• The cell wall is found in plant cells whereas the cell membrane is found in animal cells.
• The cell wall is completely permeable whereas the cell membrane is semi – permeable.
• The cell wall is made up of cellulose. The cell membrane is made up of lipids and proteins.
