Q330

Osmotic pressure in a vacuolated plant cell is usually

A.
Equal to TP
Answer
B.
Equal to WP
C.
More than DPD
D.
None of these

Answer: Option A

Solution

Answer: Option A
Solution:
Osmotic pressure in a vacuolated plant cell is usually equal to TP.
Osmotic pressure is the main cause of support in many plants. When a plant cell is in a hypotonic environment, the osmotic entry of water raises the turgor pressure exerted against the cell wall until the pressure prevents more water from coming into the cell. Here, OP becomes equal to TP.
Vacuolated plant cells behave like ideal osmometers and plasmolytic contraction of the protoplast is also a concerned.
