    • Quotes
      "All that is necessary for evil to triumph is for good men to do nothing."
      — Edmund Burke
      • Nature provides a free lunch, but only if we control our appetites.  ~William Ruckelshaus, Business Week, 18 June 1990
    • Are used in medicines, are used as soil additives, used for fuel in Finland, Ireland Germany, Poland and Russia.
      Bryophytes
      Moss, liverwort, or hornwort
      They are non vascular plants
      Reproduction via spores
      Microphylls
      Are the simplest of plants excluding the algae.
    • Pteridophytes
      Removal of heavy metals (arsenic), treatment of many diseases.
      Vascular plants with xylem and phloem
      Reproduce via spores
      Leaves are called fronds
      Have rhizoids
      They divide in twogroups: theFerns and Lycopodiophyta

    • Gymnosperms
      Lumber, soap, varnish, paints, perfumes
      Seed plants
      Vascular plants
      Reproductive structures
      They were dominant plants in the Jurassic period.
      The surviving Gymnosperms are similar in their woody habit and pattern of seed development but are not closely related.
      They have contributed to many of the evolutionary adaptations found in the biological world.
    • Angiosperms
      Source of food, they can be medicinal, its wood is used for furniture and it can provide shelter to animals.
      Vascular plants
      Produce structures cones
      Seed plants
      Reduced male parts, three cells
      Endosperm formation
      moth, bee, wasp, or beetle.
      It helps those organisms to get the necessary nutrition that they need.
