2. Bryophytes Simple plants, limited size Hold loose dirt in place Live in moist areas Depend on external water transport for reproduction: motile male gamete No vascular tissue = movement through osmosis/diffusion No true roots = have rhizoids - like root hairs (absorb water, anchor plant) No stems No leaves = similar structures but only one cell thick. Produce spores in a capsule at end of a stalk moss liverwort
3. Have vascular tissue: can be bigger Xylem: H2O + minerals Phloem: sap (sugar, AAs, hormones...) Live in moistareas Have roots, stems and leaves (fronds) Motile male gametes: can occupy terrestrial environments BUT still needs water for reproduction Spores produced in sporangia, generally on the underside of the leaf Leaves are curled, and then uncurl as they mature Filicinophytes, or Ferns frond young frond rhizome roots
12. AngiospermophytesFloweringPlants Flowering plants with roots, stems and leaves Occupy all environments Gametes are not motile (does not need water for reproduction) Seeds are produced – develop inside the ovaries in the flower Ovary develops into a fruit which aids in seed dispersal
