Question

Mesophyll is differentiated into palisade and spongy tissues in

• A. Extremely xerophytic leaves
• B. Hydrophytic leaves
• C. Monocot leaves
• D. Dicot leaves

Answer 1

The correct option is D Dicot leaves

In dorsiventral leaves, mesophyll is the ground tissue that occurs between the two epidermal layers. It is exclusively composed of chlorenchyma cells. The mesophyll is characteristically differentiated into two regions namely, an upper palisade parenchyma and a lower spongy parenchyma. Dorsiventral leaves are present in dicots. In an isobilateral leaves, undifferentiated mesophyll is present. These leaves are present in monocots. Dorsiventral leaves are absent in extremely xerophytic leaves and hydrophytic leaves.
Thus, the correct answer is option D.
