Q. No.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 B and C
(1) Cell wall
(2) Cell membrane
(3) Tonoplast
(4) Both B and C
Osmosis
(1) Diffusion of water across a differentially or selectively permeable membrane
(2) Diffusion of water across a semipermeable membrane
(3) Diffusion of water across a freely permeable membrane
(4) Both A and B
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
In which direction will osmosis occur?
(1) From A to B
(2) From B to A
(3) No net osmosis
(4) Cannot be predicted
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?
(1) From A to B
(2) From B to A
(3) No net osmosis
(4) Cannot be predicted
Apply concept of water potential and osmosis
The pressure applied in this experiment is
(1) Hydrostatic Pressure
(2) Colloidal pressure
(3) Osmotic pressure
(4) Pressure potential
Osmotic pressure is a function of
(1) Osmotic potential
(2) Solute concentration
(3) Solvent amount
(4) Water potential
Osmotic pressure is the
(1) Pressure required to stop the water diffusing in
(2) Function of solute concentration
(3) More the solute, more is the pressure needed to stop endosmosis
(4) All of these
