Question

Select the true statement for a isobilateral leaf.

• A. The stomata are present on both the surfaces
• B. Mesophyll is differentiated into palisade & spongy
• C. Cuticle is always absent on both surfaces
• D. Vascular bundles are open & conjoint

Answer 1

The correct option is A The stomata are present on both the surfaces

Monocot leaves are called isobilateral leaves since both the sides of monocot leaves are more or less similar. Isobilateral leaves orient themselves parallel to the main axis and parallel to the direction of sunlight. Epidermis is single layered, present on both surfaces and has cuticles (cuticularized) and stomata on both surfaces (amphistomatic). It is composed of compactly arranged oval or barrel shaped thin walled parenchymatous cells. Mesophyll is the ground tissue that is present between the two epidermal layers. Vascular bundles are of two types- small bundles are abundant and larger bundles are found in between them.

So the correct option is 'the stomata are present on both the surfaces'.
