Q. Read the statements given below. Which of these is wrong?
A) Sporangiospores borne in the sporangium of $Rhizopus$ are diploid structures
B) $Rhizopus$ belong to the class-Zygomycetes
C) Dominant phase in the life cycle of $Chlamydomonas$ is haploid
D) Zoospores of $Chlamydomonas$ are haploid
Explanation
The young sporangium of $Rhizopus$ contains certain amount of cytoplasm and many nuclei. The sporangium is divided into the denser, peripheral soporiferous zone and the central dome-shaped zone the columella. The protoplast of the columella is continuous with that of sporangiophore. The sporiferous zone undergo cleavage and form haploid sporangiospores.
