Detailed explanation-1: -patens. 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-2: -No, mosses do not have true roots, stems, or leaves. Mosses attach themselves to the surfaces on which they grow using small, clinging structures called rhizoids. While they help attach the plant to surfaces, they do not draw in or transfer moisture and nutrients to the plant the way true roots do.

Detailed explanation-3: -The leaves of mosses differ from true leaves as they possess no stomata, instead, the stomata may be found on the stems of these plants.

Detailed explanation-4: -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-5: -Nonvascular seedless plants, as their name implies, lack vascular tissue. Vascular tissue is specialized tissue that transports water, nutrients, and food in plants. As they lack vascular tissue, they also do not have true roots, stems, or leaves.
