Detailed explanation-1: -Mosses are a type of bryophyte, which is a group of non-vascular plants. This means they lack the vascular tissue, known as xylem and phloem, that most plants have for transporting water from roots to leaves and stems. Instead, mosses have rhizoids, or small hair-like appendages that anchor the moss and take in water.

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: -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-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.
