Question

Submerged hydrophytes exchange gases through

• A. Stomata
• B. Hydathodes
• C. Lenticels
• D. General surface

Answer 1

The correct option is D General surface

Exchange of gases occurs through general surface in submerged hydrophytes.

Totally submerged plants are the true water plants or hydrophytes. Because they are truly aquatic they have the greatest number of adaptations to life in water. The epidermal (outermost) layer shows very little, if any, sign of cuticle formation. All the surface cells appear to be able to absorb water, nutrients and dissolved gases directly from the surrounding water.
