Endodermal cells
1. Changes in CO2, K ions ABA concentration with simulataneous changes in the turgidity/ flaccidity of guard cells
2. Changes in the starch sugar concentration in the guard cells
3. Changes in the H+ concentration in the guard cells
4. Differential thickening of walls of the guard cells
Changes in CO2, K ions ABA concentration with simulataneous changes in the turgidity/ flaccidity of guard cells
1. The amount of water absorbed by closely packed and loosely packed imbibant will depend upon the temperature of the medium
2. Both will imbibe the same amount of water
3. The closely packed imbibant will imbibe less water than the loosely packed one
4. The closely packed imbibant will imbibe more water than the loosely packed one
The closely packed imbibant will imbibe less water than the loosely packed one
1. The value of TP remains same at the time of limiting, incipient and evident plasmolysis
2. The value of T.P becomes zero at the time of limiting plasmolysis and below zero during incipient and evident pladmolysis
3. The value of T.P becomes below zero at the time of limiting plasmolysis and zero at the time of incipient and evident plasmolysis
4. The value of T.P becomes negative in all the stages of plasmolysis
The value of T.P becomes zero at the time of limiting plasmolysis and below zero during incipient and evident pladmolysis
