Question:
When the cell becomes fully turgid then ........ will be zero:
When the cell becomes fully turgid then ........ will be zero:
Show Hint
Fully turgid cell: suction pressure = 0, turgor pressure = maximum.
Updated On: Jun 20, 2026
- Suction pressure
- Osmotic pressure
- Turgor pressure
- Wall pressure

The Correct Option is A
Solution and Explanation
Step 1: Understanding turgidity.
A fully turgid cell is one in which maximum water has entered the cell, making it fully swollen.
Step 2: Concept of suction pressure.
Suction pressure (diffusion pressure deficit) is the driving force for water entry into the cell.
Step 3: Condition in fully turgid cell.
When the cell is fully turgid, no more water can enter, so the driving force becomes zero.
Step 4: Evaluating other pressures.
- Osmotic pressure still exists due to solute concentration.
- Turgor pressure is maximum, not zero.
- Wall pressure is also present opposing turgor pressure.
Step 5: Logical interpretation.
Since no further water movement is possible, suction pressure becomes zero.
Step 6: Final conclusion.
Therefore, suction pressure is zero in a fully turgid cell.
A fully turgid cell is one in which maximum water has entered the cell, making it fully swollen.
