DENDROLOGY

Detailed explanation-1: -Ferns generally reproduce by producing spores. Similar to flowering plants, ferns have roots, stems and leaves. However, unlike flowering plants, ferns do not have flowers or seeds; instead, they usually reproduce sexually by tiny spores or sometimes can reproduce vegetatively, as exemplified by the walking fern.

Detailed explanation-2: -Fern Sori. 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 reproduced from spores that are gathered in clusters called sori, which are usually on the underside of the fronds. The spores can be yellow, green, brown, or black. The sori are sometimes covered with a membrane called an indusium, which will lift up when the spores are ripe.

Detailed explanation-4: -The fern, as we know it, is the sexless or sporophyte generation. Instead of growing from seed like most flowering plants, ferns come from a single spore. Spores become gametophytes, which produce male gametes and an egg structure. When fertilized, the gametophyte generates a sporophyte (the fern plant).
