Why is plasma membrane called selectively permeable membrane?
Why is plasma membrane called selectively permeable membrane?
Solution:
Cell membrane is semipermeable membrane for water. It permits the entry of gases through diffusion. Ions, sugar, amino acids, etc. pass through the plasma membrane by an active process. Plasma membrane is impermeable to certain other materials. Therefore, it is selectively permeable.
