Plants have

1. Positive water potential when cells get turgor pressure

2. Negative water potential when water is transported up a stem

3. Negative pressure is developed in the cell due to turgor pressure

4. Both 1 and 2

Cell wall is

1. Freelly permeable

2. Impermeable

3. Semipermeable

4. Selectively permeable

In plant cell, which of the following is important determinants of movement of molecules in or out of the cell?

1. Cell wall

2. Cell membrane

3. Tonoplast

4. Both 2 and 3

Osmosis

1. Diffusion of water across a differentially permeable membrane

2. Diffusion of water across a semipermeable membrane

3. Diffusion of water across a freely permeable membrane

4. Both 1 and 2

The net direction and rate of osmosis depends upon

1. Pressure gradient

2. Concentration gradient

3. Chemical potential

4. All of these

Apply concept of water potential and osmosis

Solution of which chamber has a lower solute potential?

Apply concept of water potential and osmosis

In which direction will osmosis occur?

Apply concept of water potential and osmosis

Which chamber has lower solute potential at equilibrium?

1. Chamber A

2. Chamber B

3. Both will have equal values

4. Cannot be predicted

Apply concept of water potential and osmosis

If B chamber has water potential of -2000 kPa and the A has water potential of -1000kPa, which is the chamber that has the highest Water potential?

1. Chamber A

2. Chamber B

3. Both will have equal values

4. Cannot be predicted

Apply concept of water potential and osmosis

If two solutions, A with water potential 0.2 MPa and B with water potential 0.1 MPa are separated by a selectively permeable membrane, then what will be the direction of movement of water?
