Question

When do plant cells undergo plasmolysis? (a) In hypotonic solution (b) In isotonic solution (c) In distilled water (d) In hypertonic solution

Answer 1

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. Through observation of plasmolysis and deplasmolysis, it is possible to determine the tonicity of the cell's environment as well as the rate solute molecules cross the cellular membrane.

Answer 2

Answer:

contraction of the protoplast of a plant cell which results in loss of water from the cell is called plasmolysis

plant cells undergo plasmolysis when they are kept in a hypertonic solution
