Which one of the following statements is correct about Phycomycetes?
Options
- AThe mycelium is aseptate and coenocytic.
- BA zygospore is formed by fusion of two gametes.
- CRhizopus and Albugo are examples of them.
- DAll of these
Correct answer
D. All of these
Step-by-step solution
In the members of Phycomycetes, the mycelium is aseptate and coenocytic. Asexual reproduction takes place by zoospores (motile) or by aplanospores (non-motile). These spores are endogenously produced in the sporangium. A zygospore is formed by the fusion of two gametes. These gametes are similar in morphology (isogamous) or dissimilar (anisogamous or oogamous). Some common examples are Mucor , Rhizopus (the bread mould mentioned earlier), and Albugo (the parasitic fungi on mustard).
