Question

Identify the wrong statement.

• A. Sporangiospores of Rhizopus are diploid
• B. Rhizopus belong to Zygomycetes
• C. Dominant phase of Polymyxa graminis is haploid
• D. Zoospores of Polymyxa graminis are haploid

Answer 1

The correct option is A Sporangiospores of Rhizopus are diploid

Rhizopus belongs to the zygomycetes and it forms the sporangiospore during asexual reproduction. They are endogenous, non motile, and they are haploid.
Zoospore are flagellated, motile structures formed during asexual reproduction in Polymyxa graminis. It is haploid and formed by mitosis. The dominant phase of Polymyxa graminis is haploid.
