Answer

A

Explanation

In all the septate fungi except basidiomycetes (dolipore septum), the septa are seldom complete. They are perforated and contain plasmodesmata or small central pores. Septal pores allow protoplasmic continuity between adjacent cells. This is useful for quick translocation of nutrients to all part of the body, mobilisation of reserve materials from older parts to younger parts and frem vegetative hyphae to reproductive hyphae.
