Pressure on a plant cell wall caused osmotic movement of water is called:

1. Osmotic pressure

2. Osmotic potential

3. Turgor pressure

4. Hypertonic pressure

Turgor pressure is also referred to as

1. solute potential

2. water potential

3. pressure potential

4. osmotic potential

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
