Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
An effect of osmosis where the outside solution has a lower concentration than the solution inside the cell. Movement of water molecules into the cell causes it to swell.
A
isotonic
B
exotonic
C
hypertonic
D
hypotonic
Explanation: 

Detailed explanation-1: -A hypotonic solution has a lower solute concentration compared to the intracellular solute concentration. When a red blood cell is placed in a hypotonic solution, there will be a net movement of free water into the cell.

Detailed explanation-2: -If a cell is placed in a hypotonic solution, there will be a net flow of water into the cell, and the cell will gain volume. If the solute concentration outside the cell is lower than inside the cell, and the solutes cannot cross the membrane, then that solution is hypotonic to the cell.

Detailed explanation-3: -If a cell encounters a hypotonic environment, (like pure water for instance), water will diffuse into the cell and the cell will begin to swell.

Detailed explanation-4: -Hypertonic: The solution with the higher concentration of solutes. Hypotonic: The solution with the lower concentration of solutes.

Detailed explanation-5: -Biology definition: A hypotonic solution is a solution that has lower osmotic pressure than another solution to which it is compared. It may also mean a solution that contains a lower amount of solute as compared with the solute concentration in the other solution across a semipermeable membrane.
