If water enters in a cell, the pressure exerted by its swollen protoplast is

In soil, water available for plants is

Graham`s Law is correlated with

Due to low atmospheric pressure, the rate of transpiration will

With an increase in the turgidity of a cell, the wall pressure will

Transport of food material in higher plants takes place through

The transpiration is regulated by the movements of

The osmotic potential and pressure potential of three cells (A, B, C) located in different parts of an actively transpiring plant are given below:

Passage cells are thin-walled cells found in:
