Which of the following statements correctly describes the vegetative and asexual reproductive features of Aspergillus?
Options
- AIts mycelium is aseptate and coenocytic, and asexual spores are produced exogenously.
- BIts mycelium is branched and septate, and asexual spores are produced endogenously.
- CIts mycelium is aseptate and coenocytic, and asexual spores are produced endogenously.
- DIts mycelium is branched and septate, and asexual spores are produced exogenously.
Correct answer
D. Its mycelium is branched and septate, and asexual spores are produced exogenously.
Step-by-step solution
Aspergillus belongs to the class Ascomycetes. According to NCERT, members of Ascomycetes have a branched and septate mycelium. Their asexual spores are conidia, which are produced exogenously on special mycelium called conidiophores. Aseptate and coenocytic mycelium, along with endogenous asexual spores, are characteristic features of Phycomycetes, not Ascomycetes. Answer: Its mycelium is branched and septate, and asexual spores are produced exogenously.
