Question:

Which of the following statements regarding the class phycomycetes is correct ? 

(A) These are found in aquatic habitats and on decaying wood in moist and damp places or as obligate parasites on plants 

(B) Mycelium in these fungi is aseptate and coenocytic 

(C) Asexual reproduction occurs by motile z0ospores and by non-motile apanospores 

(D) All of these

Answer:  option (D) "All the above"

Explanation:

Phycomycetes are characterized by the aseptate coenocytic hyphae. Asexual reproduction occurs by motile zoospores or non-motile aplanospores produced endogenously inside sporangia. Members of Phycomycetes are found in aquatic habitats and on decaying wood in moist and damp places or as obligate parasites on plants. 

Hence, option (D) "All the above" is the correct answer.
