Question

25.a) Define plasmolysis.
b) Why is plasma membrane termed selectively permeable?​

Answer 1

Answer:

The plasma membrane is called as selectively permeable membrane because it regulates the

Answer 2

Answer:

Plasmolysis is the process in which cells lose water in a hypertonic solution. The reverse process, deplasmolysis or cytolysis, can occur if the cell is in a hypotonic solution resulting in a lower external osmotic pressure and a net flow of water into the cell.

The plasma membrane is called a selectively permeable membrane as it permits the movement of only certain molecules in and out of the cells. ... As the plasma membrane acts as a mechanical barrier, the exchange of material from its surroundings through osmosis or diffusion in a cell won't take place.
