Introduction to the Plant Kingdom - 4 The Non-Vascular Plants The non-vascular plants include the mosses, hornworts and liverworts. Because they lack vascular tissue they are small in vertical stature, and typically grow in clumps or masses. Most lack a cuticle and many are capable of withstanding long periods of desiccation. They attach to their substrate with “rhizoids”, but absorb water and minerals through all surface cells. Some have air pores for diffusion of gases. Some Bryophytes have a thallus (flattened-shaped) structure and others are tiny,

Unformatted text preview: three-dimensional with an axis and “leaves”, called phyllodes, attached. {A true leaf has vascular tissue, so technically Bryophytes can't have leaves, so we call their leaf-looking structures phyllodes.} They have apical meristems. All Bryophytes disperse by air-borne spores and water is required to transport the motile sperm for fertilization. The gametophyte generation is dominant in their life history. The three non-vascular plant phyla are: Hepatophyta Anthocerophyta Bryophyta Hepatophyta Anthocerophyta Bryophyta...
