DENDROLOGY

Detailed explanation-1: -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-2: -Nonvascular plants do not possess any special organs for the absorption and transport of water; instead, the plant cells absorb water and nutrients from their wet surroundings at their surface by diffusion and pass them from cell to cell.

Detailed explanation-3: -Nonvascular plants are also known as bryophytes. Examples of nonvascular plants include mosses, hornworts and liverworts. These small plants typically spend their lives in moist environments where they are able to absorb water and nutrients directly through the surface of the plant.

Detailed explanation-4: -Characteristics of Nonvascular Plants Most bryophytes are small. They not only lack vascular tissues; they also lack true leaves, seeds, and flowers. Instead of roots, they have hair-like rhizoids to anchor them to the ground and to absorb water and minerals (see Figure below).

Detailed explanation-5: -Nonvascular plants survive only in moist habitats. They do not have leaves, roots, or stems, they are low-growing plants, and they reproduce by forming spores.
