Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The animal cells swell and burst because it’s placed in which solution?
A
Hypotonic solution
B
Hypertonic solution
C
Hypertonec solution
D
Isotonic solution
Explanation: 

Detailed explanation-1: -If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, there is no net water movement, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.

Detailed explanation-2: -When an animal cell is placed in a hypotonic solution the animal cell will burst due to the net movement of water from the solution into the cell. This net movement was caused by a lower solute concentration in the solution than in the cell.

Detailed explanation-3: -Cell wall can withstand dilute hypotonic media and prevents bursting of cells. Therefore, plant cells withstand changes in environmental concentration much better than animal cells which get burst in such conditions.

Detailed explanation-4: -So, for a cell to swell, it has to be placed in a hypotonic solution.

Detailed explanation-5: -A plant cell and an animal cell is kept in a hypotonic solution.
