Q. Consider the following statements about class-Oomycetes? I. Member may be obligate parasite on plants II. The mycelium is aseptate and coenocytic III. Asexual reproduction involves the formation of spore containing sac or sporangia. In aquatic conditions, the sporangia produces zoospores Which of the statements given above are correct?
A) I and II
B) I and III
C) II and III
D) I, II and III
Explanation
Members of class-Oomycetes are found in aquatic habitats and on decaying wood in moist and damp places or as obligate parasites on plants. Thallus is mycelial. The hypae are coenocytic (i.e., aseptate and multinucleate). Asexual reproduction occurs by the formation of spores produced inside the sac-like sporangia. Terrestrial species produces aplanospores and aquatic species produces zoospores
