Question

In which of the following plants, is there no transpiration?

• A. Aquatic, submerged plants
• B. Plants living in deserts
• C. Aquatic plants with floating leaves
• D. Plants growing in hilly regions

Answer 1

The correct option is A Aquatic, submerged plants

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 is absent in submerged hydrophytic plants because the stomata are completely absent in the leaves of the submerged plants, e.g Anacharis and Potamogeton.
