DENDROLOGY

Detailed explanation-1: -Plants we see as ferns or horsetails are the sporophyte generation. The sporophyte generally releases spores in the summer. Spores must land on a suitable surface, such as a moist protected area to germinate and grow into gametophytes .

Detailed explanation-2: -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-3: -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-4: -A fern is part of a group of plants classified in the Division Pteridophyta. This class of nonflowering vascular plants reproduce by spores and possess true roots, stems, and complex leaves. That’s why you may also see people refer to a fern as a pteridophyte.
