Question

3 main functions of cell membrane

Answer 1

1-It is selectively permeable membrane and hence it regulates the transfer of minerals and ions b/t cell and external environment.

2-It also acts as a physical barrier b/t cell and external environment.

3-It is a base for attachment b/t the cytoskeleton and cell wall in plant cell

Answer 2

Answer:

Functions of cell membrane:

1. Protects the cells by acting as a

barrier.

2. The Quasi (semi)-fluid nature enables

the cell membrane to take part in Cell

growth, formation of inter-cellular

junctions, Cell division, Secretion of

various substances, and Endocytosis.

3. It receives chemical messengers

from other cells.

4. It acts as a receptor.

5. It regulates the transport of

substances across the cell membrane.
