Question

Gaseous exchange in land plants takes place through stomatal opening, while in submerged hydrophytes it takes place by

• A. Lenticels
• B. Stomata
• C. Hydathodes
• D. General surface of the cells by diffusion

Answer 1

The correct option is D General surface of the cells by diffusion

Submerged plants do not show stomata, lenticels, and hydathodes. These structures are present in terrestrial plants for the exchange of gasses and physiological processes, like transpiration and guttation. In submerged hydrophytes exchange of gasses and nutrients occurs through general plant surface.

So, the correct answer is option D.
