At which stage in the life cycle of Rhizopus meiosis takes place?
Correct answer: A. Formation of sporangiophore via germination of zygospore.
- A. Formation of sporangiophore via germination of zygospore.
- B. Formation of spores in sporangia
- C. Fusion of two hyphae
- D. Formation of Zygote by fusion of gametangia.
Explanation
In Rhizopus, the zygospore is diploid and undergoes meiosis when it germinates, producing haploid spores in a newly formed sporangium. Fusion of hyphae and gametangia occurs before the diploid zygospore stage, so choosing either fusion option confuses fertilization with meiosis.

About Classification of Biological Molecules
Biological molecules are classified as carbohydrates, lipids, proteins and nucleic acids, with water, minerals and vitamins also supporting cellular processes. The key distinctions involve their monomers, chemical bonds, structures and functions, including glucose and starch, fatty acids and triglycerides, amino acids and polypeptides, and nucleotides in DNA and RNA.
