Question

what is meant by plasmolysis​

Answer 1

Answer:

contraction of the protoplast of a plant cell as a result of loss of water from the cell.

Answer 2

Answer:

Plasmolysis definition in biology is the contraction of the cell due to protoplast shrinking upon exposure to a hypertonic solution. In animal cells, the equivalent condition is termed crenation. Similarly, the plant and the animal cells lose water as water molecules diffuse to its concentration gradient. In animal cells though, the net efflux of water results in the cells appearing wrinkled. The plant cells, due to the presence of the cell wall, do not appear wrinkled. Rather, they form concave pockets as in the case of concave plasmolysis or they form a full sphere in the case of convex plasmolysis.
