Movement of water from cell B to A

No movernent of water

Equilibrium between the two

Movement of water from cell A to B

generally polar in nature

transported in the direction of concentration gradient 

transported with the help of carrier proteins 

all of the above

imbibition

endosmosis

capillarity

deplasmolysis.

less negative to more negative potential

more negative to less negative potential

same potentials

none of the above.

in day time - for gaseous exchange

in day time - no gaseous exchange

in night time only - for gaseous exchange

in night time only - no gaseous exchange.

water leaves the cell

water enters the cell

no exchange of water takes place

solute goes from the cell into water.

Root pressure

Transpiration

Capillarity

All of these

It is an active transport.

It cause transport of molecules from low concentration to high concentration.

 It is insensitive to inhibitors.

 It is a very specific transport.

soil by adding water and humus

water saturated soil then heating the soil till it is dry and then measuring the weight of soil

soil by adding water, boimass and humus

soil from different locations with biomass.

 ${\mathrm{\Psi }}_{\mathrm{w}}= {\mathrm{\Psi }}_{\mathrm{s}} + {\mathrm{\Psi }}_{\mathrm{p}}$

 ${\mathrm{\Psi }}_{\mathrm{w}} = {\mathrm{\Psi }}_{\mathrm{s}}-{\mathrm{\Psi }}_{\mathrm{p}}$

 ${\mathrm{\Psi }}_{\mathrm{w}}={\mathrm{\Psi }}_{\mathrm{s}}$

 ${\mathrm{\Psi }}_{\mathrm{w}}={\mathrm{\Psi }}_{\mathrm{p}}-{\mathrm{\Psi }}_{\mathrm{s}}$

no flow of water

A. Orgnic food moves upward through xylem

B. Organic food move up through phloem

C. Inorgani food move upward and downward through xylem

D. Organic foo move upward and downward through phloem

a-Multidirectional

a-Bidirectional

b- Mulltidirectional

b- Unidirectional

Passive

Over shorter distances

No energy expenditure

Movement in ordered fashion

1 .Dependent on living system

2. Ovious in gases and liquids

3 .In solids rather than of solids is more likely

4. Diffusion is very important in plants since it is the only means for gaseous movement within the plant boy

1 .Grdient of concentration 

2. Permeaility of the membrane separating them 

3. Temperature, Pressure 

4. Gas constant 

1 .Solubility in proteins 

2 .Solubility in carbohydrates 

3 .Solubility in lipids 

4. Solubility in glycolipids
