Bryophytes are Non-vascular type plants without a vascular system consisting of xylem and phloem . Although non-vascular plants lack these particular tissues, many possess simpler tissues that are specialized for internal transport of water .Bryophytes are plants because they are photosynthetic with chlorophylls a and b, store starch, are multicellular, develop from embryos, have sporic meiosis—an alternation of generations—and cellulose cell walls. Some mosses have simple water and food conduction‐type cells (but these are not the same as the xylem and phloem tissues of vascular plants). They have no lignified cell walls (like wood) for strength, so the plants remain small. Neither do they have leaves, stems, or roots. They absorb water from their surfaces by capillarity. The “leaves” of leafy liverworts and mosses are undifferentiated tissues and lack stomata, and the moss “stems” lack vascular tissues.
