Question

Which one of the following statements is correct about Phycomycetes?

• A. The mycelium is aseptate and coenocytic.
• B. A zygospore is formed by fusion of two gametes.
• C. Rhizopus and Albugo are examples of them.
• D. All of these

Answer 1

Answer: (D)

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).
