Detailed explanation-1: -primitive fungi produce spores in sporangia, which are saclike sporophores whose entire cytoplasmic contents cleave into spores, called sporangiospores. Thus, they differ from more advanced fungi in that their asexual spores are endogenous.

Detailed explanation-2: -The sporangium forms on the sporangiophore and contains haploid nuclei and cytoplasm. Spores are formed in the sporangiophore by encasing each haploid nucleus and cytoplasm in a tough outer membrane. During asexual reproduction, these spores are dispersed via wind and germinate into haploid hyphae.

Detailed explanation-3: -In fungi, the spores are formed on a reproductive knob-like structure known as the sporangium. They produce minute haploid spores that grow into new organisms in favourable conditions.

Detailed explanation-4: -A sporangium can be globose to obovoid or flask-or dumbbell-shaped to somewhat cylindrical in a few taxa. Its outer wall can be smooth, have terminal spines, or be covered with calcium oxalate crystals or spines, and at maturity it can deliquesce, persist, or become evanescent, depending on the species.

Detailed explanation-5: -Spore Formation is an Asexual Reproduction technique. Many Spores are housed in sacs known as Sporangia. The plants produce hundreds of spores and the spore sac bursts. These spores are dispersed into the air, where they germinate and create a new plant under favourable conditions.
