8. Simple Organism Notes

  1. 1. Kingdoms: Monera, Protista, Fungi, & Plantae
  2. 2. Primary Producters <ul><li>Capable of using light energy to perform photosynthesis and thus create their own food </li></ul>
  3. 3. Autotrophs & Heterotrophs <ul><li>Autotroph – organism capable of producing own food </li></ul><ul><li>Heterotroph – organism that needs to ingest nutrients/food </li></ul>
  4. 4. Prokaryotic & Eukaryotic <ul><li>Prokaryotic – cells that do not have a nucleus </li></ul><ul><li>Eukaryotic – cells that have a defined nucleus </li></ul>
  5. 5. Kingdom Monera <ul><li>Prokaryotic </li></ul><ul><li>Autotrophic or Heterotrophic </li></ul><ul><li>Bacteria & Cyanobacteria </li></ul>
  6. 6. Bacteria <ul><li>Unicellular </li></ul><ul><li>Rod-shaped with cell wall </li></ul><ul><li>Smallest living creatures on earth </li></ul><ul><li>Prokaryote </li></ul><ul><li>Kingdom Monera </li></ul>
  7. 9. Cyanobacteria <ul><li>Blue-Green Algae </li></ul><ul><li>Photosynthetic Bacteria </li></ul><ul><li>Important role in the accumulation of oxygen in our atmosphere </li></ul>
  8. 11. Kingdom Protista <ul><li>Eukaryotic </li></ul><ul><li>Combine characteristics of plants & animals </li></ul><ul><li>Includes: unicellular algae, protozoans, and multi-cellular algae </li></ul>
  9. 12. Unicellular Algae <ul><li>Widely used term to describe mostly aquatic, photosynthetic eukaryotes </li></ul>
  10. 13. Diatoms <ul><li>Unicellular algae </li></ul><ul><li>Cell walls made of silica </li></ul><ul><li>Drifts in water (plankton) </li></ul>
  11. 15. Dinoflaggellates <ul><li>Unicellular algae </li></ul><ul><li>Two unequal size flagella </li></ul><ul><li>Cell wall of armored plates of cellulose </li></ul>
  12. 17. Foraminiferans <ul><li>Protozoans (animal like protists) </li></ul><ul><li>Have pseudopodia (cytoplasmic extenstions) </li></ul><ul><li>Also called forams </li></ul>
  13. 19. Ciliates <ul><li>Protozoans </li></ul><ul><li>Have hair-like cilia to move </li></ul><ul><li>Can live in gills, intestines, skin of fish, or attached to surfaces </li></ul>
  14. 21. Multi-Cellular Algae <ul><li>Called “Seaweeds” </li></ul><ul><li>More complex than unicellular algae but not as complex as terrestrial plants </li></ul><ul><li>Categorized in Kingdom Protista, however some put them in Plantae </li></ul>
  15. 22. Parts: <ul><li>Thallus : </li></ul><ul><li>The entire structure </li></ul><ul><li>Stipe : </li></ul><ul><li>Stem-like part </li></ul><ul><li>Blade : </li></ul><ul><li>Leaf-like part </li></ul><ul><li>Holdfast : </li></ul><ul><li>Holds on but not a true root capable of transport </li></ul>
  16. 23. Green algae <ul><li>Most found in freshwater or terrestrial environments </li></ul><ul><li>Unicellular </li></ul><ul><li>Bright green because chlorophyll is not masked. </li></ul>
  17. 25. Brown Algae <ul><li>Almost all marine </li></ul><ul><li>Make up the most complex and largest seaweeds </li></ul><ul><li>Make up kelp </li></ul>
  18. 27. Red Algae <ul><li>Most found in marine environments </li></ul><ul><li>Largest group of algae </li></ul>
  19. 29. Kingdom Fungi <ul><li>500 species of marine fungi </li></ul><ul><li>Decomposers of dead matter </li></ul><ul><li>Non-photosynthetic </li></ul><ul><li>Plant-like </li></ul><ul><li>Eukaryotic </li></ul>
  20. 30. Kingdom Plantae <ul><li>Eukaryotic </li></ul><ul><li>Photosynthetic </li></ul><ul><li>Almost all multi-cellular </li></ul>
  21. 31. Seagrasses <ul><li>Not really grasses, more closely related to lilies </li></ul><ul><li>Form meadows in shallow, tropical waters </li></ul>
  22. 32. Salt Tolerant plants <ul><li>Most plants that inhabit salt marshes and shorelines are just tolerant to salt water and do not have adaptations especially for it </li></ul>
