Question

The lower surface of ________ leaves will have more number of stomata on the surface.

• A. dorsiventral
• B. isobilateral
• C. thin
• D. thick

Answer 1

The correct option is A

dorsiventral

In dorsiventral leaf, the number of stomata will be more on lower surface. This feature enhances gas exchange between leaf surface and the atmosphere for the processes of photosynthesis and respiration.

Whereas in isobilateral leaf, stomata are uniformly distributed on both the surfaces.
