Question

What is plasmolysis? What happens to a plasmolysed cell when it is placed in water?

Answer 1

Plasmolysis is the contraction of cells within plants due to the loss of water through osmosis. It is when the cell membrane peels off of the cell wall and the vacuole collapses when placed in a hypertonic environment.This phenomenon occurs when water is drawn out of the cell and into the extracellular (outside cell) fluid. The movement of water occurs across the membrane moving from an area of high water concentration to an area of lower water concentration outside the cell, and is known as osmosis

Answer 2

Answer:

Plasmolysis is the process by which the cytoplasm of the cell gets shrinked due to the loss of water by osmosis. When a plasmolysed cell is places in water, the cell absorbs water from outside due to difference in solute concentration inside and outside the cell. By absorbing water the cell becomes turgid.
