Detailed explanation-1: -The bumps that you see on the undersides of the fronds are spore cases, called sporangia. The spores inside the spore cases are the beginnings of a fascinating life cycle.

Detailed explanation-2: -Sori (singular: sorus) are groups of sporangia (singular: sporangium), which contain spores. Sori are usually found on the underside of the blade. Young sori are commonly covered by flaps of protective tissue called indusia (singular: indusium).

Detailed explanation-3: -Ferns are primitive plants that do not reproduce by seeds. Instead, ferns produce “spores” in orange or brown, dusty “sori” (singular sorus) on the undersides of their leaves. Sori may appear as small or large raised dots, or as a diffuse rusty coating under the leaf.

Detailed explanation-4: -Sori is found in fungi and ferns.
