Question

In isobilateral leaf, the number of stomata per unit area are

• A. More on upper surface
• B. More on lower surface
• C. Approximately same on both the surfaces
• D. Absent on both the surface

Answer 1

The correct option is C Approximately same on both the surfaces

Isobilateral leaves show similar structure on both the surfaces and is usually vertically oriented to expose both surfaces to the sun. The stomata distribution is even on both the surfaces of leaves, the dorsal and the ventral surface (epidermis). In dorsiventral, the stomata is restricted only to lower epidermis. Thus, the correct answer is an option C.
