In a dorsiventral leaf, the mesophyll tissue is differentiated into two distinct regions. What are these regions?
- A.Palisade parenchyma and spongy parenchyma.
- B.Aerenchyma and chlorenchyma.
- C.Epidermis and hypodermis.
- D.Xylem and phloem.
Show correct answer & step-by-step solution
Correct answer: A — Palisade parenchyma and spongy parenchyma.
Solution
- Dorsiventral leaves are typical of dicots.
- The mesophyll is differentiated into an adaxial palisade parenchyma and an abaxial spongy parenchyma.
- Palisade cells are elongated and vertically arranged.
- Spongy cells are oval or round with large intercellular spaces.
- Hence the answer is (A).
