  1. Kingdom PlantaePrimitive Plants Mr. Skirbst Life Science Topic 13

  2. Plants

  3. Kingdom Plantae

  4. Kingdom Plantae “Plants” • Multicellular organisms

  5. Kingdom Plantae “Plants” • Multicellular organisms • Autotrophs (undergo photosynthesis)

  6. Kingdom Plantae “Plants” • Multicellular organisms • Autotrophs (undergo photosynthesis) • Have chlorophyll

  7. Kingdom Plantae “Plants” • Multicellular organisms • Autotrophs (undergo photosynthesis) • Have chlorophyll • Have cell walls

  8. Primitive Plants • Plants with simple structures • Do not produce seeds

  9. Multicellular Algae

  10. Multicellular Algae • Made of many cells

  11. Multicellular Algae • Made of many cells • Autotrophs (have chlorophyll)

  12. Multicellular Algae • Made of many cells • Autotrophs (have chlorophyll) • Must live in or near water (they have no roots or stems)

  13. Multicellular Algae • Made of many cells • Autotrophs (have chlorophyll) • Must live in or near water (they have no roots or stems) • Do not have seeds

  14. Multicellular Algae • Made of many cells • Autotrophs (have chlorophyll) • Must live in or near water (they have no roots or stems) • Do not have seeds • Divided into 3 phyla

  15. 1. Brown Algae

  16. 1. Brown Algae • Most live in ocean

  17. 1. Brown Algae • Most live in ocean ex. kelp (seaweed) giant kelp can grow 100m high (kelp is edible)

  18. 1. Brown Algae • Most live in ocean ex. kelp (seaweed) giant kelp can grow 100m high (kelp is edible) ex. sargassum – floating algae

  19. 1. Brown Algae • Most live in ocean ex. kelp (seaweed) giant kelp can grow 100m high (kelp is edible) ex. sargassum – floating algae Sargasso Sea – Bermuda

  20. 2. Red Algae • Most grow on benthic rocks

  21. 2. Red Algae • Most grow on benthic rocks • Red pigment helps absorb small amounts of light

  22. 2. Red Algae • Most grow on benthic rocks • Red pigment helps absorb small amounts of light • Human uses include:

  23. 2. Red Algae • Most grow on benthic rocks • Red pigment helps absorb small amounts of light • Human uses include: * agar – grow bacteria

  24. 2. Red Algae • Most grow on benthic rocks • Red pigment helps absorb small amounts of light • Human uses include: * agar – grow bacteria * carrageenan –ice cream, dressing, chocolate milk, cake frosting, toothpaste…

  25. 3. Green Algae • Most live in fresh water ponds

  26. 3. Green Algae • Most live in fresh water ponds • Too much results in “green ponds” (over-productive)
