Non-vascular plants are those without a vascular system (that is they lack xylem and phloem) and grow from spores. They do not have roots, stems, or leaves (although the lobes of some liverworts can look like leaves). Some non-vascular plants however do possess specialized tissues for internal transport of water.
Non-vascular plants include two groups - the bryophytes and algae. Also included here are lichens as they are a symbiosis between one or more algae and a fungus.
