Transport In Plants Ques 56
56. Water potential in the leaf tissue is negative $(−)$ during
(a) excessive transpiration
(b) low transpiration
(c) excessive absorption
(d) guttation
Show Answer
Answer : d
Hints & Solutions
(d) Pure water has maximum water potential. Water potential in the leaf tissue becomes lower than pure water under conditions of excessive humidity when the leaves cannot lose water by transpiration. Hence, water is lost as droplets via hydathodes by the process of guttation.
