Detailed explanation-1: -Nonvascular plants like mosses, lichens, and liverworts are the opposite of vascular plants. They do not have vascular tubes to carry nutrients and water from the soil. Instead, they act like sponges soaking up any water that forms on their surfaces.

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: -How Do Nonvascular Plants Get Water? Vascular plants have xylem and phloem that transport water and nutrients to the rest of the plant. Nonvascular plants absorb nutrients and water directly into their cells.

Detailed explanation-4: -Water enters and leaves cells through osmosis, the passive diffusion of water across a membrane. In plants, water always moves from an area of higher water potential to an area of lower water potential.

Detailed explanation-5: -Vascular seedless plants have vascular tissue, a specialized tissue that transports water and nutrients throughout the plant. Two “circulatory” tissues and a supporting molecule enabled vascular plants to colonize dry land.
