Solution

The lower surface of leaf will have more number of stomata in a dorsiventral leaf.

Explanation:

Dorsiventral leaves face a high rate of transpiration and the transpiration occurs through stomata, so to avoid the percentage of transpiration rate lower surface of the dorsiventral leaves contains more number of stomata and a lesser number of stomata in the upper surface but In the isobilateral leaf, the number of stomata is the same on both surfaces.
