The different cell has a different structure and function and everything is unique in its own way. Biomembrane is a semipermeable covering around the cell and organelles, which separates them from the external environment. They can be extended, folded and repaired quickly. They play a vital function for a living cell. Biomembrane that covers the cell is called cell membrane or plasmalemma and biomembrane which covers the organelles is called subcellular membrane. So take this quiz on the structure and function of the cell and increase your knowledge about it.
