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: -In plants, osmosis means water molecules moving from cells that have lots of water to cells that have less water.

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.

Detailed explanation-4: -Diffusion is the distribution of a substance away from an area where it is highly concentrated. In this way, water and nutrients move from cells that are full to cells that are empty. Diffusion uses no energy. Active transport, however, does require a plant to use energy.
