Question
Read the following statements and pick up the correct statements
I. Potometer works on the principle of amount of water absorbed equals the amount of water transpired
II. The osmotic value of guard cells is highest when the stomata are open the lowest when the stomata are closed
III. Loss of water by cells without external sign of leaf drooping is as temporary wilting
IV. Water potential found in root hair cells is generally -1 to -4atm

Solution
The correct option is D I,III
The potometer works on the principle of capillarity where the movement of water is measured by calculating the distance at a particular time Loss of water by the cell resulting in drooping is a type of temporary wiltingThe water potential of root hair cells is negative with value ranging from 0.5 - 1.0 MPa So, the correct answer is 'I , III'
