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: -This is due to the fact that the salt water is a hypertonic solution when compared to the plant cells, and water inside the plant cells will diffuse by osmosis out of the cells in order to reduce the concentration of the salt solution. This will reduce the turgor pressure inside the cells and they will wilt.

Detailed explanation-2: -For example, a solution containing 10% salt is hypertonic. When a cell is placed in a hypertonic environment, there is a net movement of water to the outside of the cell (from the higher water environment inside the cell). The cell shrinks in response.

Detailed explanation-3: -Salt Sucks, Cells Swell Water in cells moves toward the highest concentration of salt. If there is more salt in a cell than outside it, the water will move through the membrane into the cell, causing it to increase in size, swelling up as the water fills the cell in its imperative to combine with the salt.

Detailed explanation-4: -if we keep a boiled plant cell in a 10+ salt solution it will loose water and will shrink because it has gained water by boiling but when kept in 10+ salt solution the concentration of water becomes higher inside the cell and lower outside the cell.

Detailed explanation-5: -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.
