DIFFUSION AND OSMOSIS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Describe what would happen if you placed a plant cell in a 0.0 M solution.
A
The cell would lyse
B
The cell would be turgid
C
The cell would plasmolyze
D
The cell would be flaccid
Explanation: 

Detailed explanation-1: -Cells with a cell wall will swell when placed in a hypotonic solution, but once the cell is turgid (firm), the tough cell wall prevents any more water from entering the cell. When placed in a hypertonic solution, a cell without a cell wall will lose water to the environment, shrivel, and probably die.

Detailed explanation-2: -A cell placed into a hypotonic solution will swell and expand until it eventually burst through a process known as cytolysis. These three examples of different solute concentrations provide an illustration of the spectrum of water movement based on solute concentration through the process of osmosis.

Detailed explanation-3: -If a cell is placed in a hypotonic solution, the cell will swell and burst.

Detailed explanation-4: -Turgidity is a cellular phenomenon of cell swelling because of the absorption of high fluid content. The cells take up water and it gets stored in vacuoles resulting in swelling of cells. Turgidity occurs because of the presence of the cell wall and the osmoregulatory effect of the vacuole.
