Final answer:
The division of fungi that produces spores in sac-like structures is Ascomycota, which includes morels and forms cup-like structures known as ascocarps.
Step-by-step explanation:
The division of fungi that produces spores in sac-like structures, includes morels as an example, and often forms cup-like structures in addition to the sac-like sporangia is Ascomycota. This phylum is characterized by the formation of an ascus, or plurally asci, which are the sac-like structures that contain the haploid ascospores. Morels and truffles are edible forms of Ascomycota, while others like Aspergillus oryzae are used in fermentation processes. Conversely, Basidiomycota, known as club fungi, produce basidiospores in club-shaped structures called basidia, typically found in mushrooms. Zygomycota, or the conjugated fungi, primarily produce non-septate hyphae that fuse during sexual reproduction to form a zygosporangium.
