Q. In which of the following plants, there will be no transpiration?
A) Aquatic, submerged plants
B) Plants living in deserts
C) Aquatic plants with floating leaves
D) Plants growing in hilly regions
Explanation
The loss of water from aerial parts of living plants is known as transpiration. Transpiration may be stomatal (80-90%), cuticular (3-9%) and lenticular (0.1%). Transpiration remain absent in submerged hydrophytic plants because stomata are completely absent in the leaves of submerged plants, e.g., Anacharis and Potamogeton.
