DENDROLOGY

Detailed explanation-1: -Bryophytes such as mosses and algae are non-vascular plants. They do not possess true roots, stems and leaves. Xylem and phloem are absent. Bryophytes include liverworts, hornworts and mosses.

Detailed explanation-2: -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-3: -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.
