Question

In a dorsiventral leaf, location of palisade tissue and phloem is respectively on the _______ surfaces.

• A. Adaxial and Abaxial
• B. Adaxial and Adaxial
• C. Abaxial and Adaxial
• D. Abaxial and Abaxial

Answer 1

The correct option is A Adaxial and Abaxial

Palisade parenchyma is found immediately below the upper epidermis. It is 2 to 3 layered, with compactly arranged tubular cells, rich in parietal chloroplasts. Spongy parenchyma is found above the lower epidermis. These cells are very loosely arranged to enclose air spaces some of which open into stomata. The adaxial surface is the upper surface of a leaf. The abaxial surface is the lower surface of a leaf. Phloem is found to be towards the abaxial surface of the leaf.

Thus, the correct option is (A).
