Question

Coenocytic mycelium occurs in

• A. Dueteromycetes
• B. Ascomycetes
• C. Phycomycetes
• D. Basidiomycetes

Answer 1

Answer: (C)

Phycomycetes

• In the algal fungi (Phycomycetes) the mycelium in the vegetative phase usually lacks internal partitions of any kind.
• The hyphae are thus multinucleate and aseptate. The mycelium is a continuous mass. It grows terminally by the apical elongation of the hyphae accompanied by increase in the number of nuclei by nuclear divisions.
• The aseptate, multinucleate mycelium is called coenocytic. The septa in the aseptate, coenocytic mycelium, however, are formed only to cut off reproductive structures, or to seal off a damaged portion.

So the correct option is C.
