    • BRYOPHYTES:
      • Is a traditional name used to refer to all the land.
      • They are plants that do not have true vascular tissue.
      • They have a haploid gametophyte, each of whose cells contains a fixed number of unpaired chromosomes
      • Give rise to a diploid sporophyte.
      • They reproduce by spores
      • Microphylles.
      USES:
      Interactions:
      • Ecology
      • horticulture
      • household uses
      • medicine and even food.
      Symbiotic-Mutualism
    • PTERIDOPHYTES:
      • They are vascular plants.
      • They reproduce and disperse only via spores.
      • Useful in the removal of heavy me falls, specially arsenic.
      • They are extinct.
      • Share a single common ancestor but they are not a clade.
      Interactions:
      Symbiotic-Mutualism
      USES:
      • Decorativeplants
    • GYMONOSPERM

      • Pine.
      • Fir.
      • Spruce
      • Cedar.
      • Theyare seed and vascular plants.
      • There are between 700 and 900 extant or currently living species of gymnosperms.
      • They are spore-bearing plants with a sporophyte dominant life cycle.
      • The gymnosperms reproduce structures cones.
      • The gymnosperms originated in the late carboniferous period.
    • Angyosperms:
      Mutualism
      Symbiosis is when bothorganismsbenefit.
      • Are the most diversity of land plant
      • Are seed producing plant like gymnosperms.
      • They are 8 groups of living angiosperms: amborella, calendonia, nyphaeales, chloranthales, woody plants etc.
      • Vascular plants
      • Angiosperms provide the primary food sources for animals and provide oxygen of us to breath.
      Mutual
      Uses:
      • Healing characteristics
      • Physoactive substances
    • Uses:
      FERNS:
      • Food
      • cut foliage
      • houseplants
      • They have xylem and phloem(making them vascular plants).
      • Ferns do not have either seeds or flowers(the reproduce via spores)
      • They have a life cycle referred to as alternation of generations, characterized by diploid saprophytic and a haploid gametophyte phase
      • Ferns are leafy plants that grow in moist areas under forest canopy.
      • Ferns reproduce differently from the conifers and flowering plants
    • Plants:
