Botanically, mosses are non-vascular plants that absorb water and nutrients mainly through their leaves and harvest carbon dioxide and sunlight to create food by photosynthesis. They have no vascular system to transport water. They do not have a well-developed xylem. Their conducting tissue is made up of parenchyma.

Branch roots are of two kinds: long-branching geotropic roots and short-branching apogeotropic roots, which are referred to as coralloid because of their irregular, beady appearance. The coralloid roots contain symbiotic cyanobacteria (blue-green algae), which fix nitrogen. It also collects water and soil nutrients and store carbohydrates.
