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: -Mosses have some water-conducting cells, but they do not have the empty, lignin-reinforced cells that allow vascular plants to transport water with strong pressure gradients. Thus, mosses have very limited water transport ability and can’t grow very tall.

Detailed explanation-3: -They include pteridophytes, gymnosperms and angiosperms. Non-vascular plants lack a specialised vascular system for transporting water and nutrients. They may contain simple structures that may specialise to perform transportation, e.g. algae and bryophytes.

Detailed explanation-4: -Characteristics of Nonvascular Plants They not only lack vascular tissues; they also lack true leaves, seeds, and flowers. Instead of roots, they have hair-like rhizoids to anchor them to the ground and to absorb water and minerals (see Figure below).

Detailed explanation-5: -They lack true roots, stems, or leaves. They are called non-vascular plants because of the absence of vascular tissues (xylem and phloem) that functions for the conduction of food, water, and minerals.
