Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A plant cell with a 20% salt solution is placed into a beaker with a 10% salt solution. What will happen to the plant cell?
A
Cytolysis
B
Plasmolysis
C
It will shrink
D
It will swell
Explanation: 

Detailed explanation-1: -Explanation: The cells will shrink if placed in a solution of sugar or salt in water due to osmosis. When an animal cell and plant cell will be kept in a solution of sugar or salt in water, the cell will undergo the process of osmosis.

Detailed explanation-2: -When plant cells are put in really salty water, water diffuses/moves out of the cell and the central vacuole shrinks. When animal cells are put in salty water, water diffuses/moves out of the cell and the cell shrivels up.

Detailed explanation-3: -A cell place in salty solution would loose water as water will move from cell to surrounding hypertonic medium by the process of osmosis causing the cell to shrivel up.

Detailed explanation-4: -As the salt concentration is higher outside the cell than inside, water will rush from inside the cell to outside the cell to try and normalize the concentrations to make them isotonic. This will result in the cell shriveling up in a process called plasmolysis.
