AP BIOLOGY

Detailed explanation-1: -Liverworts (Marchantiophyta) – Typically, they are less than 4 inches in height, they are tiny non-vascular plants having lobed, ribbon or leaf-like photosynthetic tissues as opposed to leaves. Stems are absent and rhizoids are extremely fine. Often, they are found inhabiting in colonies which carpet the ground.

Detailed explanation-2: -These are the nonvascular plants or bryophytes (mosses, liverworts, and hornworts), the seedless vascular plants (clubmosses and ferns including, horsetails, club mosses, and whisk ferns), gymnosperms (conifers, cycads, Ginkgo, and gnetophytes), and angiosperms, or flowering plants.

Detailed explanation-3: -Mosses and liverworts are small, primitive, non-vascular plants. They lack the conductive tissue most plants use to transport water and nutrients. Instead, moisture is absorbed directly into cells by osmosis.

Detailed explanation-4: -The non-vascular plants include mosses, hornworts and liverworts, and some algae. They are generally small plants limited in size by poor transport methods for water, gases and other compounds. They reproduce via spores rather than seeds and do not produce flowers, fruit or wood.
