What happens to a plant cell that is placed into a hypotonic solution?
A
It shrinks
B
Plasmolysis
C
It swells
D
Cytolysis
Explanation: 

Detailed explanation-1: -When a cell is kept in a hypotonic medium, the cells take up water from external medium and swell up. In plant cells, the cell membrane creates a pressure against the cell wall, which exerts an equal pressure against the swollen cell but do not burst.

Detailed explanation-2: -Plant cells swell up when kept in hypotonic solution because plant cells absorb large amounts of water in hypotonic solution such that the vacuole is completely filled with water and the cytoplasm presses against the cell wall. But it does not get burst due to the presence of cell wall.

Detailed explanation-3: -When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell. Diagram of red blood cells in hypertonic solution (shriveled), isotonic solution (normal), and hypotonic solution (puffed up and bursting).

Detailed explanation-4: -If a cell is placed in a hypotonic solution, the cell will swell and burst.

Detailed explanation-5: -A hypertonic solution has increased solute, and a net movement of water outside causing the cell to shrink. A hypotonic solution has decreased solute concentration, and a net movement of water inside the cell, causing swelling or breakage.
