Lacking vascular tissue, these early plants generally have a prostrate form and grow closely appressed to the substrate. They lack true roots but have anchoring cells called rhizoids that extend from the gametophyte. Bryophytes have a gametophyte dominant life cycle and the sporophytes grow from the megagametophyte.

They do not have roots, but have long dead cells capable of water absorbency via apoplastic transport, these cells are called rhizoid cells. Their sporophyte is reduced to sporogon, which is simply a sporangium with setamosses: stalk of the sporogon (see) (stalk), and is usually parasitic. Gametophyte of bryophytes starts its development from a protonema, thread of cells.
