Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the term that means “a solution that causes a cell to swell due to water moving into the cell because there is a lower concentration of solute outside the cell ‘’?
A
hypotonic solution
B
hypertonic solution
C
isotonic solution
D
passive transport
Explanation: 

Detailed explanation-1: -In hypotonic solutions, there is a net movement of water from the solution into the body. A cell placed into a hypotonic solution will swell and expand until it eventually burst through a process known as cytolysis.

Detailed explanation-2: -Cytolysis, or osmotic lysis, occurs when a cell bursts due to an osmotic imbalance that has caused excess water to diffuse into the cell. Water can enter the cell by diffusion through the cell membrane or through selective membrane channels called aquaporins, which greatly facilitate the flow of water.

Detailed explanation-3: -Hypotonic Solution Definition Hypotonic solution refers to a solution containing a lower amount of solute in comparison to the solute concentration in other solutions, across a semipermeable membrane. Such a solution has a decreased solute concentration and a total movement of water in the cell.

Detailed explanation-4: -(ii) Hypotonic solution: A solution having a lesser concentration of solute inside as compared to outside the cell is called a hypotonic solution.

Detailed explanation-5: -A solution with a lower solute concentration as compared to a solvent is called a hypotonic solution. In contrast, a solution with a high solute concentration as compared to a solvent is called a hypertonic solution.
