Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What happens when the vacuole is empty or skinny?
A
Mild Turgor pressure
B
Low turgor pressure
C
High turgor pressure
D
Regular turgor pressure
Explanation: 

Detailed explanation-1: -In the absence of enough water, however, central vacuoles shrink and turgor pressure is reduced, compromising the plant’s rigidity so that wilting takes place.

Detailed explanation-2: -Turgidity helps the plant to stay upright. If the cell loses turgor pressure, the cell becomes flaccid resulting in the wilting of the plant.

Detailed explanation-3: -The action of turgor pressure on extensible cell walls is usually said to be the driving force of growth within the cell. An increase of turgor pressure causes expansion of cells and extension of apical cells, pollen tubes, and other plant structures such as root tips.

Detailed explanation-4: -The loss of turgor causes the violent detachment of the living protoplast from the cell wall. The plasmolytic process is mainly driven by the vacuole. Plasmolysis is reversible (deplasmolysis) and characteristic to living plant cells.

Detailed explanation-5: -The central vacuole in a plant cell occupies the majority of the cellular volume and plays a key role in turgor regulation.
