Detailed explanation-1: -Most ferns produce 64 spores in each sporangium. Sporangia are aggregated into clusters called sori.

Detailed explanation-2: -Sporangia can be found at the tips or along the sides of stems or leaves. In the case of fungi, the sporangia are usually found at the tips of the hyphae.

Detailed explanation-3: -Leaves that bear sporangia are called sporophylls. If the plant is heterosporous, the sporangia-bearing leaves are distinguished as either microsporophylls or megasporophylls. In seed plants, sporangia are typically located within strobili or flowers.

Detailed explanation-4: -A sporangium (pl., sporangia) is a plant or fungal structure producing and containing spores. Sporangia occur on angiosperms, gymnosperms, ferns, fern allies, bryophytes, algae, and fungi. Their spores are sometimes called sporangiospores.
