  1. 2. OBJECTIVES: <ul><li>engage participants to activities that would develop their background about Botany, especially Plant Taxonomy; </li></ul><ul><li>appreciate plant’s economic importance; and </li></ul><ul><li>develop camaraderie among the participants. </li></ul>
  2. 4. PLANT TAXONOMY <ul><li>science that finds, describes, classifies, identifies and name plants </li></ul><ul><li>Two goals are identification and classification of plants </li></ul>Plant identification is the determination of the identity of an unknown plant. Plant classification is the placing of known plants into groups
  3. 5. <ul><li>Classifying organisms </li></ul><ul><li>“ Linnaean taxonomic system” by </li></ul><ul><li>Carolus Linnaeus </li></ul><ul><li>“ Taxa” </li></ul>Taxonomy <ul><li>Kingdom: </li></ul><ul><li>Phylum: </li></ul><ul><li>Class: </li></ul><ul><li>Order: </li></ul><ul><li>Family: </li></ul><ul><li>Genus: </li></ul><ul><li>Species: </li></ul>MAJOR TAXONOMIC LEVELS plantae magnoliophyta magnoliopsida rosales  rosaceae rosa
  4. 6. CHARACTERISTICS OF PLANTS <ul><li>multicellular  </li></ul><ul><li>eukaryotic  </li></ul><ul><li>autotrophic  </li></ul><ul><li>alternative generations in life cycle </li></ul><ul><li>Undergo photosynthesis </li></ul><ul><li>have a cell wall made of cellulose </li></ul>
  5. 7. <ul><li>Non-vascular plants   </li></ul><ul><li>without a vascular system </li></ul><ul><li>possess tissues specialized for internal transport of water </li></ul>Division Bryophyta <ul><li>include liverworts and mosses </li></ul><ul><li>lack water-conducting tissues </li></ul><ul><li>have rhizoids, stemlike and leaflike structures </li></ul><ul><li>colonize bare rock </li></ul><ul><li>Liverworts </li></ul><ul><li>flattened, lobed bodies and represent a small fraction of bryophyte species </li></ul><ul><li>With numerous rhizoids </li></ul>
  6. 8. <ul><li>Examples of Liverworts </li></ul>
  7. 11. <ul><li>2. Moss </li></ul><ul><li>stem like structure with radially arrange leaf like structure </li></ul>Examples of Moss
  8. 13. <ul><li>Vascular plants </li></ul><ul><li>have vascular tissue </li></ul>Division Psilophyta <ul><li>seedeless vascular plant </li></ul><ul><li>has branched stem and lacks true roots and leaves </li></ul><ul><li>stem is green and carries photosynthesis </li></ul><ul><li>Example of this is whisk fern </li></ul>
  9. 14. EXAMPLE OF WHISK FERN
  10. 15. <ul><li>Division Sphenophyta: horsetail </li></ul><ul><li>Division Lycophyta: club mosses </li></ul><ul><li>seedless vascular plants </li></ul><ul><li>do not produce seed </li></ul>Examples
  11. 16. Division Pterophyta: ferns <ul><li>have roots and leaves or stem </li></ul><ul><li>vary in appearance </li></ul><ul><li>low- lying but some are tall </li></ul>Examples
  12. 17. Division cycadophyta: cycads <ul><li>extremely ancient group </li></ul><ul><li>sister group to all other living seed plants </li></ul><ul><li>stout and woody trunk with a crown of large, hard and stiff, evergreen leaves </li></ul><ul><li>have pinnate leaves. </li></ul>Examples
  13. 18. Division Coniferophyta: conifers <ul><li>trees or shrubs that bear their seeds in cones </li></ul><ul><li>Some conifers are the oldest plants on earth. </li></ul><ul><li>have either needles or scale-like leaves. </li></ul><ul><li>Most abundant gymnosperms today. </li></ul>Examples
  14. 19. Division Gnetophyta: woody plants <ul><li>have different vessel elements </li></ul><ul><li>mostly woody climbers in tropical forests </li></ul>Examples
