EVERYDAY SCIENCE

Detailed explanation-1: -They are small in size and may possess simpler structures for the conduction of water and nutrients. Bryophytes such as mosses and algae are non-vascular plants. They do not possess true roots, stems and leaves. Xylem and phloem are absent.

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: -Nonvascular plant: a plant that does not have tubes.

Detailed explanation-4: -Mosses are non-vascular plants with about 12, 000 species classified in the Bryophyta. Unlike vascular plants, mosses lack xylem and absorb water and nutrients mainly through their leaves.

Detailed explanation-5: -Within vascular plants is the phloem, the vessel that transports food, and the xylem, which transports water. Nonvascular plants are small, simple plants without a vascular system. They do not have a phloem or xylem.
