Q. Primary phloem develops from

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.
