As do all plants, bryophytes alternate a gametophytic generation with a sporophytic one (asporic meiosis, a life cycle in which meiosis gives rise tospores, not gametes).

The Life Cycle of Bryophytes Characteristics of Bryophytes Habitats of Bryophytes Examples of Bryophytes Lesson Summary What are Bryophytes? They lack the same structures as vascular plants which transport water and nutrients through vein-like structures to their tissue. Mosses are widely distributed from pole to pole and occupy a broad range of habitats. However, bryophytes lack flowers, wood and a true root system. General characteristic features The plant body of bryophyte is gametophyte and is not differentiated into root, stem and leaf like structure. because they lack a protective epidermis What are they?
