Question

Dorsiventral leaf has

• A. spongy parenchyma on upper side
• B. spongy parenchyma on both sides
• C. palisade parenchyma on lower side
• D. palisade parenchyma on upper side

Answer 1

The correct option is D palisade parenchyma on upper side

Dorsiventral leaves orient themselves at an angle to the main axis and perpendicular to the direction of sunlight. Most dicots have dorsi-ventral leaves that are net-veined, including most trees, bushes, garden plants and wildflowers. Mesophyll is the ground tissue between the upper and lower epidermis. In dorsiventral leaf, it is differentiated into palisade parenchyma and spongy parenchyma. Palisade parenchyma lies towards the upper epidermis and consists of one, two or three layers of elongated cells, densely packed with no intercellular spaces and contains chloroplast

So, the correct option is 'palisade parenchyma on upper side'
