Detailed explanation-1: -Non-flowering plants include ferns, clubmosses, horsetails, mosses, lichens, and fungi. These are spore-producing plants, a major feature distinguishing them from the seed-producing flowering plants.

Detailed explanation-2: -Mosses are non-flowering plants which produce spores and have stems and leaves, but don’t have true roots. Mosses, and their cousins liverworts and hornworts, are classified as Bryophyta (bryophytes) in the plant kingdom.

Detailed explanation-3: -Physical Characteristics The stems are weak and free standing, and are usually greenish to brown colored. It reproduces by spores (since no seeds are found). The sporophytes are short lived and have long, unbranched stems. They are mostly dependent on the gametophyte for water and nutrition.

Detailed explanation-4: -Ferns and mosses have neither cones nor flowers. Instead, they have special parts that produce spores. The spore cases appear as small specks on the underside of the plant’s leaves. Each spore can grow into a new plant.
