Plant Water Relations Water Potential Dpd

Two cells A and B are contiguous. Cell A has osmotic pressure 10 atm, turgor pressure-7 atm, and diffusion pressure deficit 3 atm. Cell B has an osmotic pressure of 8 atm, turgor pressure of 3 atm, and diffusion pressure deficit of 5 atm. The result will be:

1. Movement of water from cell B to A

2. No movement of water

3. Equilibrium between the two

4. Movement of water from cell A to B

The water potential of pure water is:

1. Less than zero

2. More than zero but less than one

3. More than one

4. Zero

Addition of more solutes in a given solution will:
1. not affect the water potential at all
2. raise its water potential
3. lower its water potential
4. make its water potential zero
