The water potential of pure water at standard temperatures, which is not under any pressure is taken to be equivalent to
1. Zero
2. –${\mathrm{\psi }}_{\mathrm{S}}$
3. ${\mathrm{\psi }}_P$
4. +${\mathrm{\psi }}_{\mathrm{S}}$

Turgor pressure is also referred to as

1. solute potential

2. water potential

3. pressure potential

4. osmotic potential

What is never zero in a cell-

1. Solute potential

2. Water potential

3. DPD

4. Diffusion pressure

Loss of solutes from a cell leads to

1. Increase in water potential

2. Decrease in solute potential

3. Increase in pressure potential

4. All of the above

The interconnected cells which do not show symplastic movement of water are:

1. Mesophyll cells
2. Tracheids
3. Xylem parenchyma cells
4. Cells of endodermis
