3. Organisms that make their own food Carbon fixers Autotrophs

4. Prokaryotes

5. Simple cells No internal membranes No Organelles No Nucleus

7. Bacteria

8. Prokaryotic cells found in large numbers everywhere Main form of reproduction is mitosis

9. Heterotrophic Bacteria

10. Non-photosynthetic bacteria Mostly decomposers Found in sediment

11. Autotrophic Bacteria

12. Photosynthetic bacteria on the Earth’s surface Chemosynthetic bacteria near hydrothermal vents

14. An explosion of growth & reproduction of a species due to optimum conditions

15. Blue-Green Algae

16. Phylum: Cyanophyta Cyanobacteria

17. Characteristics Unicellular, planktonic, microscopic, photosynthetic, sexual & asexual reproduction

18. Distinguishing Prokaryotic, deposits CaCO 3 (Stromatolites), top producer world-wide, blue-green pigment, helps cause red tides

19. Stromatilites

20. Calcium carbonate deposited by blue- green algae that build up on the ocean floor to make large mounds

21. Calcium carbonate deposits that build up on the ocean floor White cliffs of Dover

22. Algae

23. General term for any photosynthetic organisms that are not true plants

24. Red Tides

25. Condition when several organisms emit reddish toxins that cause fish kills

26. Protista

27. Single cellular eukaryotes & multi-cellular algae

28. Diatoms

29. Phylum : Crysophyta

30. Characteristics Unicellular, planktonic, microscopic, photosynthetic, sexual & asexual

31. Distinguishing Eukaryotic, yellow- brown pigment, glass shell, (deposits silicon dioxide), top producer in temperate to polar zones

34. Dinoflagellates

35. Phylum: Pyrrhophyta

36. Characteristics Unicellular, planktonic, microscopic, photosynthetic, sexual & asexual

37. Distinguishing Eukaryotic, cellulose shell, 2 uneven flagella, bioluminescence, can live within other organisms, top producer in Tropics

39. Other Photosynthetic Protists

40. Silicoflagellates, Coccolithophorids Cryptomonads

41. Protozoa Heterotrophic or animal-like protists

42. Foraminiferans Protozoan with a calcium carbonate shell

44. Radiolarians Protozoan with a glass shell

46. Ciliates Protozoan with hairlike structures on its surface that is used for mobility

48. Pseudopodia False feet Oozing cytoplasm

49. Ooze Fine sediment on the ocean floor

50. Calcareous Ooze Fine sediment made up of calcium carbonate

51. Siliceous Ooze Fine sediment from silicates or silicone dioxide

52. Diatomaceous Ooze Fine sediment from diatom shells

53. Foramaceous Ooze Fine sediment made from the shells of forams

54. Radiolarian Ooze Fine sediment made from radiolarian shells

55. Multi-cellular Algae: Seaweed

56. Parts of Seaweed

57. Thallus: entire structure Rhizoid: root-like struct. Stipe: stem-like structure Blade: leaf-like structure Pneumatocysts: air sacs

59. Types of Seaweed

60. Green Algae Red Algae Brown Algae

61. Green Algae Phylum: Chlorophyta Characteristics: mostly unicellular, bright green, small

63. Red Algae Phylum: Rhodophyta Characteristics: also small, red pigment, most species, some deposit CaCO 3

65. Brown Algae Phylum: Phaeophyta Characteristics: True seaweed, most complex. Ex: Kelp

67. Sargasso Weed Floating seaweed Lacks rhizoid In Sargasso Sea

68. Seaweed Economics Food source Algin Carrageenan

69. Fungi

70. Lichens A symbiotic relationship between fungi & algae Encrusts rocks near sea shore

71. Marine Plants

73. Seagrasses

74. Eelgrass: Temperate Turtle grass: Tropical Manatee grass: Tropical Surf grass: Binds to rocks in the surf

75. Marsh Grasses

76. Cord grass or Spartina grass: found in the marshy area above the highest tides

77. Mangrove Trees

78. A tropical shrub-like tree that is salt tolerant, can colonize the surf zone, & has above ground root system
