Mosses are small, green plants that lack vascular tissues, which are the specialized tissues that transport water and nutrients in higher plants. They reproduce via spores and are typically found in damp or shady locations.
Mosses have a life cycle that involves two main stages: the gametophyte stage and the sporophyte stage. The gametophyte is the dominant stage in the life cycle of mosses, while the sporophyte is short-lived and dependent on the gametophyte for nutrients.
Mosses are important for the environment as they help to retain moisture in the soil and prevent erosion. They also contribute to the cycling of nutrients and provide habitat for small invertebrates and microorganisms.
