Past, Present and Future of Plant Diversity

  1. 1. Past, Present and Future of Plant Diversity <ul><li>STC-GROUP 3 </li></ul><ul><li>LAGUNA STATE POLYTECHNIC UNIVERSITY-SAN PABLO CITY CAMPUS, </li></ul><ul><li>PHILIPPINES </li></ul>
  2. 2. OBJECTIVES <ul><li>To define Plant Ecology. </li></ul><ul><li>To determine the connection of plant reproduction, biological interaction and distribution to plant ecology. </li></ul><ul><li>To differentiate the scene of the past, present and future of plant diversity. </li></ul>
  3. 3. PLANT ECOLOGY
  4. 4. Plant Ecology <ul><li>It is a sub-discipline of ecology which studies the distribution and abundance of plants, the interactions among and between members of plant species, and their interactions with their environment. </li></ul>
  5. 5. <ul><li>includes the study of plants and their environment. </li></ul><ul><li>can include the study of entire ecosystems. </li></ul>
  6. 6. Plant Reproduction <ul><li>Plant reproduction is the production of new individuals or offspring in plants, which can be accomplished by sexual or asexual means. </li></ul>
  7. 7. Biological Interactions <ul><li>In the natural world no organism exists in absolute isolation. </li></ul><ul><li>It can involve individuals of the same species or individuals of different species . </li></ul>
  8. 8. Biological Interactions <ul><li>Competition </li></ul><ul><li>Facilitation </li></ul><ul><li>Herbivory </li></ul>
  9. 9. Distribution <ul><li>Plant communities are broadly distributed into biomes based on the structure of dominant plant species. </li></ul>
  10. 10. Distribution <ul><li>Colonisation and local extinction </li></ul><ul><li>Abundance </li></ul>
  11. 11. PAST
  12. 12. Time Era Period Epoch Plants & Microorganisms 10, 000 years ago to present Cenozoic Quaternary Holocene Decline of some woody plants; rise of herbaceous plants. 2 Pleistocene Extinction of many plant species.
  13. 13. 5 Cenozoic Tertiary Pliocene Development of grasslands; decline of forest. 25 Miocene Flowering plants continue to diversify. 38 Oligocene Spread of forests; flowering plants. 55 Eocene Gymnosperms & flowering plants dominant. 65 Paleocene Many now-extinct woody flowering plants.
  14. 14. 144 Mesozoic Cretaceous Rise of flowering plants. 213 Jurassic Gymnosperms common. 248 Triasssic Gymnosperms dominant; ferns common.
  15. 15. 286 Paleozoic Permian Conifers diversify; cycads appear. 360 Carboniferous Forests of ferns, club mosses, horsetails, and gymnosperms; mosses & liverworts. 408 Devonian Plants diversify & become well-established; first forest; gymnosperms appear; bryophytes appear. 438 Silurian Vascular plants appear; algae dominant in aquatic environments. 505 Ordovician Marine algae dominant. 570 Cambrian Algae; bacteria & cyanobacteria; fungi.
  16. 16. Archaeamphora longicervia Cooksonia
  17. 18. PRESENT
  18. 19. <ul><li>As we study the plant ecology, people can focus on topics like climate change and its effect on plants, plant evolution, how plants disseminate themselves in nature, symbiotic relationships between plant species, plant diseases, and so forth. </li></ul>
  19. 21. FUTURE
  20. 22. <ul><li>Genetic Engineering of Plants Holds Great Promise </li></ul>
  21. 23. Crocodilian nepenthes Plants at Planet Mars
  22. 24. MEMBERS: <ul><li>MELODY DE LAS ALAS </li></ul><ul><li>MARY ROSE DELLOSA </li></ul><ul><li>ROSELYN MABILANGAN </li></ul><ul><li>JHON ALFRED SAGISI </li></ul><ul><li>MARIE DAISYLYN TIQUIS </li></ul>
