Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is it called when a cell shrinks?
A
Cytolysis
B
Plasmolysis
C
Isotonic
D
Hypotonic
Explanation: 

Detailed explanation-1: -Plasmolysis is defined as the process of contraction or shrinkage of the protoplasm of a plant cell and is caused due to the loss of water in the cell. Plasmolysis is an example of the results of osmosis and rarely occurs in nature.

Detailed explanation-2: -Plasmolysis is mainly known as shrinking of cell membrane in hypertonic solution and great pressure. Plasmolysis can be of two types, either concave plasmolysis or convex plasmolysis.

Detailed explanation-3: -Plasmolysis is the shrinking of the cytoplasm of a plant cell in response to diffusion of water out of the cell and into a high salt concentration solution. During plasmolysis, the cell membrane pulls away from the cell wall.

Detailed explanation-4: -Plasmolysis is when plant cells lose water after being placed in a solution that has a higher concentration of solutes than the cell does. This is known as a hypertonic solution. Water flows out of the cells and into the surrounding fluid due to osmosis.

Detailed explanation-5: -Plasmolysis in a plant cell is defined as the process of shrinkage of the protoplasm as a result of loss of water from the cell. It occurs when plant cells are placed in a solution that has a higher concentration of solutes than the cell does. In this, plant cell is kept in hypertonic solution.
