Answers
Answer:
Rhizopus stolonifer, a species of bread mold, produces sporangia that bear sporangiospores (asexual spores). Grant Heilman/Encyclopædia Britannica, Inc. The more primitive fungi produce spores in sporangia, which are saclike sporophores whose entire cytoplasmic contents cleave into spores, called sporangiospores.(b) In the fungus, Rhizopus, some specialised hyphae give rise to a globular structure (known as sporangium) that contains spores.
