2. Plants

3. Kingdom Plantae

4. “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. -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. -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)
