Options
- AA IV, B III, C II, D I
- BA III, B IV, C II, D I
- CA IV, B III, C I, D II
- DA III, B IV, C I, D II
Correct answer
D. A III, B IV, C I, D II
Step-by-step solution
In a dorsiventral (dicotyledonous) leaf, the adaxial epidermis generally bears fewer stomata than the abaxial epidermis, and its mesophyll is differentiated into adaxially placed palisade parenchyma and abaxially placed spongy parenchyma. In an isobilateral (monocotyledonous) leaf, the mesophyll is undifferentiated. In grasses, certain adaxial epidermal cells along the veins modify into large, empty, colourless cells called bulliform cells. Therefore, the correct match is A III, B IV, C I, D II. Answer: A III, B IV
