The pressure exerted by the protoplast due to the entry of water against the rigid cell wall is termed as
1 Pressure potential
2 Osmotic potential
3 Solute potential
4 Water potential
Explanation:
Pressure can build up in a plant system when water enters a plant cell due to diffusion causing a pressure built up against the cell wall, it makes the cell turgid, this increases the pressure potential.

By convention, the water potential of pure water at standard temperatures, which is not under any pressure, is taken to be
1 Negative
2 Positive
3 1
4 Zero
Explanation:
By convention, the water potential of pure water at standard temperatures, which is not under any pressure, is taken to be zero.

Statement A : In plants the cells usually contain a large central vacuole and contribute to the solute potential of the cell. Statement B : Osmosis occurs spontaneously in response to a driving force.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
Explanation:
Both the statements are correct.

The water potential of pure water decreases on addition of
1 Solute
2 Solvent
3 Both 1 and 2
4 None of these
Explanation:
If some solute is dissolved in pure water, the solution has fewer free water molecules and the concentration (free energy) of water decreases, reducing its water potential.
