Question

Rate of transpiration in a dorsiventral leaf is

• A. Greater at the upper surface
• B. Greater at the lower surface
• C. Equal at both the surface
• D. Not related to surfaces

Answer 1

The correct option is B Greater at the lower surface

More transpiration occurs in lower surface of dorsiventral leaf because the number of stomata present in the ventral side of the leaf is more than the number of stomata present in the dorsal side of leaf.

Therefore, the correct answer is option B.
