Question

Epistomatous (stomata on the upper surface) condition is ........... type of adaptation.

• A. Terrestrial
• B. Aquatic
• C. Aerial
• D. None of the above

Answer 1

Answer: (B)

Aquatic

Epistomatous have stomata only on the top part of the leaf as the underside of the leaf rests on the surface of the water and the rest of the plant is submerged. Since the plant is submerged in water the plant is not threatened by drought or have to close its stomata during the high heat of the day to conserve water.

So, the correct answer is 'Aquatic'.
