  2. 2. Quotes<br />"All that is necessary for evil to triumph is for good men to do nothing."<br />— Edmund Burke<br /><ul><li>Nature provides a free lunch, but only if we control our appetites.  ~William Ruckelshaus, Business Week, 18 June 1990</li></li></ul><li>Are used in medicines, are used as soil additives, used for fuel in Finland, Ireland Germany, Poland and Russia.<br />Bryophytes<br />Moss, liverwort, or hornwort<br />They are non vascular plants<br />Reproduction via spores<br />Microphylls<br />Are the simplest of plants excluding the algae.<br />
  3. 3. Pteridophytes<br />Removal of heavy metals (arsenic), treatment of many diseases.<br />Vascular plants with xylem and phloem<br />Reproduce via spores<br />Leaves are called fronds<br />Have rhizoids<br />They divide in twogroups: theFerns and Lycopodiophyta<br />Interactwithearthworms in anindirectway. Ithelps in thesoilfortheorganism.<br />
  4. 4. Gymnosperms<br />Lumber, soap, varnish, paints, perfumes<br />Seed plants<br />Vascular plants<br />Reproductive structures<br />They were dominant plants in the Jurassic period.<br />The surviving Gymnosperms are similar in their woody habit and pattern of seed development but are not closely related.<br /> They have contributed to many of the evolutionary adaptations found in the biological world.<br />
  5. 5. Angiosperms<br />Source of food, they can be medicinal, its wood is used for furniture and it can provide shelter to animals.<br />Vascular plants<br />Produce structures cones<br />Seed plants <br />Reduced male parts, three cells<br />Endosperm formation<br />moth, bee, wasp, or beetle.<br />It helps those organisms to get the necessary nutrition that they need.<br />
