NEET BIOLOGY

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 are plants that do not have any special internal pipelines or channels to carry water and nutrients. Instead, nonvascular plants absorb water and minerals directly through their leaflike scales. Nonvascular plants are usually found growing close to the ground in damp, moist places.

Detailed explanation-3: -Since nonvascular plants have no internal vessels through which water and nutrients can move, they must absorb their water and substances directly from their environment. This is why nonvascular plants such as mosses are very small and grow low to the ground.

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: -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.
