Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What cellular condition would cause water to cross the cell membrane and fill a plant cells vacuole?
A
Hypertonic
B
Hypotonic
C
Isotonic
D
None of the above
Explanation: 

Detailed explanation-1: -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-2: -Animal cells tend to do best in an isotonic environment, plant cells tend to do best in a hypotonic environment.

Detailed explanation-3: -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-4: -Here water can be called hypotonic solution and salt solution can be called hypertonic solution. The movement occurs to balance concentration and form equilibrium.

Detailed explanation-5: -A plant cell in hypotonic solution In a hypotonic solution, water moves into the plant cells through the cell wall. The plasma membrane will swell without bursting the rigid cell wall and become turgid (stiff). This allows the cell to regulate water consumption and survive dry spells.
