Question

Consider the phenomenon shown in the given diagram and select the incorrect statement regarding this phenomenon.
(i) Low root pressure is responsible for this phenomenon.
(ii) This happens in plants growing in hot and dry conditions.
(iii) All plants do not show this phenomenon.
(iv) It occurs through stomata.
(v) It occurs when absorption is low and transpiration is high.

• A. (ii), (iii) and (v) only
• B. (i), (ii) and (v) only
• C. (i), (ii), (iv) and (v)
• D. (iii) only

Answer 1

The correct option is C (i), (ii), (iv) and (v)

The given figure illustrates the process of guttation in which loss of water occurs in the form of water droplets from the leaf margins. It occurs through hydathodes which are found at the tips of leaf veins. This process can be observed in plants growing in warm and humid conditions. Conditions like high root pressure, low transpiration and high absorption are responsible for this process to occur.
