NEET BIOLOGY

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: -Characteristics of Nonvascular Plants 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-4: -Nonvascular plants are non-flowering plants that do not have specialized tissues like vascular tissues to transport water and minerals to the rest of the plant body. They are low-growing forms of plants that are found growing in moist habitats.

Detailed explanation-5: -Non-vascular plants such as liverworts and mosses move water and nutrients by osmosis and diffusion. Because non-vascular plants are small (typically one cell thick) they do not need conducting tissues and a complex system to move water; whereas vascular plants are large, and need a more complex system.
