Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A HYPOTONIC solution has a ____ concentration of solute than the cell and the cell will ____ when placed into a hypotonic solution.
A
lower; swell
B
lower; shrink
C
higher; swell
D
higher; shrink
Explanation: 

Detailed explanation-1: -Hypotonic solution is a solution, which contains lesser solute concentration. In such a case, the water molecules move from outside to the inside of the cell through the cell membrane. This process is called as endosmosis by which cell gains water and swells up.

Detailed explanation-2: -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-3: -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.

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

Detailed explanation-5: -If a cell is in a hypertonic solution, the solution has a lower water concentration than the cell cytosol, and water moves out of the cell until both solutions are isotonic. Cells placed in a hypotonic solution will take in water across their membranes until both the external solution and the cytosol are isotonic.
