Q. Primary phloem develops from
✅ Correct Answer: (D)
provascular tissue
Explanation:
- Primary phloem is part of the primary vascular system in plants and develops from the provascular tissue (also called procambium).
- Provascular tissue (Procambium) is a type of primary meristem that gives rise to primary xylem and primary phloem.
- Lateral meristem (e.g., vascular cambium) is responsible for secondary growth, not primary phloem formation.
- Protoderm gives rise to the epidermis, not vascular tissues.
- Extrastelar cambium is not directly involved in primary phloem development.
