    5. Microscope Review

    9. Cyanobacteria Domain Eubacteria

    10. Cyanobacteria Domain Eubacteria Kingdom Monera

    11. Cyanobacteria Domain Eubacteria Kingdom Monera All are prokaryotes

    12. Cyanobacteria Domain Eubacteria Kingdom Monera All are prokaryotes The only bacteria capable of photosynthesis

    13. Cyanobacteria Domain Eubacteria Kingdom Monera All are prokaryotes The only bacteria capable of photosynthesis Used to be considered algae

    14. Cyanobacteria- blue-green bacteria Make a wet-mount of the pond water and use the key to find some cyanobacteria

    15. Algae Domain Eukarya

    16. Algae Domain Eukarya Kingdom Protista

    17. Algae Domain Eukarya Kingdom Protista All are eukaryotes

    18. Algae Domain Eukarya Kingdom Protista All are eukaryotes Almost all are photoautotrophs

    19. Algae Domain Eukarya Kingdom Protista All are eukaryotes Almost all are photoautotrophs Most are aquatic, some found on land

    20. Algae Domain Eukarya Kingdom Protista All are eukaryotes Almost all are photoautotrophs Most are aquatic, some found on land Some are unicellular, others are multicellular

    21. Algae Domain Eukarya Kingdom Protista All are eukaryotes Almost all are photoautotrophs Most are aquatic, some found on land Some are unicellular, others are multicellular Some Exhibit Alternation of Generations (a multicellular haploid stage and a multicellular diploid stage)

    22. Algae Domain Eukarya Kingdom Protista All are eukaryotes Almost all are photoautotrophs Most are aquatic, some found on land Some are unicellular, others are multicellular Exhibit Alternation of Generations (a multicellular haploid stage and a multicellular diploid stage) Green Algae, Diatoms, Red Algae Brown Algae

    23. Chlorophyta: Ancestors of higher plants

    26. To Do: Make a wet mount of pond water and use the key to identify some species Look at slides of Spirogyra (conjugation) Look at herbarium specimens to see larger examples

    27. Bacillariophyta: the largest group of algae Common Name: diatoms

    28. Diatoms 20-25% of all organic carbon fixation could be from diatoms Large % of plankton is diatoms Fossilized diatoms make up diatomaceous earth used for making abrasive cleaners, reflective paint, filters etc. Some store food in the form of oil cod liver oil comes from cod that eat lots of diatoms NREL in Golden,CO looking for ways to make biofuel from diatoms

    29. To Do: Make a wet mount of diatomaceous earth Look at prepared slide of diatoms Look at the products made from diatomaceous earth Remember that diatom cell walls are made of silica!!!

    30. Rhodophyta: The Red Algae

    31. Products from Red Algae

    32. To Do: Look at herbarium specimens of red algae Look at products made from red algae

    33. Phaeophyta: the largest algae Common Name: brown algae, kelp, seaweed

    34. Phaeophyta: the largest algae

    35. Products from brown algae

    36. To Do Look at herbarium specimens (make sure to identify the blade, stipe, and holdfast) Look at products from brown algae

    37. Sample Quiz Question 1. a. What are the cells walls of diatoms made of? b. Name a product that contains diatomaceous earth. c. To what Kingdom do diatoms belong?

    38. Sample Quiz Question State one difference between algae and cyanobacteria. State one similarity between algae and cyanobacteria.

    39. Sample Quiz Question Give both the common and scientific name of the phylum of algae that contains members with the pigment phycoerythrin.

    40. Next Week Quiz Lab Topics 12, 14, 15 Bring in an article or reference to share with your group
