Detailed explanation-1: -Nonvascular plants are very small because their lack of a vascular system means they do not have the mechanics required for transporting food and water far distances.
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: -They do not grow tall and are low-lying plants, so they do not need vascular tissues. They use cytoplasmic streaming, diffusion, or osmosis to transport metabolites and other nutrients between their cells.
Detailed explanation-4: -Characteristics of Nonvascular Plants Instead of roots, they have hair-like rhizoids to anchor them to the ground and to absorb water and minerals (see Figure below). Bryophytes occupy niches in moist habitats, but, as they lack vascular tissue, they are not very efficient at absorbing water.
Detailed explanation-5: -Nonvascular plants lack seeds and vascular tissue. These plants are very short because they cannot move nutrients and water up a stem.
