  1. Algae fits in 3 kingsdoms
    -kingdom monera

    -kingdom protista

    -kingdom plantae
  2. (algae fits in 3 kingdoms) Blue-green algae (cyanobacteria)
    -prokaryotic

    *Kingdom Monera
  3. (algae fits in 3 kingdoms) Diatoms, Dinoflagellates, some green algae (3)
    -eukaryotic

    -unicellular

    Kingdom Protista
  4. (algae fits in 3 kingdoms) Green algae, brown, and red (3)
    -eukaryotic

    -multicellular (large)

    Kingdom Plantae
  5. 6 Charateristics to identify algae
    • -pigments and color
    • -size and appearance
    • -ability to move
    • -cell wall
    • -food reserve/storage material
    • -reproduction
  6. (characteristics of algae) Pigments and color (3)
    -all have chlorophyll a

    -some have chlorophyll c or d (depends on water depth)

    -acessory pigments
  7. (characteristics of algae) Size and appearance (4)
    -unicellular: single cell

    • -colonial: small group of cells
    • *often circular

    -filament: long chains of cells, can be branched

    -sheet like or large
  8. (characteristics of algae) Ability to move (2)
    • -mobile or move
    • *flagella: 1 to 2 tail like
    • *gliding

    -non-mobile: dont move
  9. (characteristics of algae) Cell wall material (2)
    • -cellulose (most)
    • * plants

    • -silica (glass)
    • *diatoms
  10. (characteristics of algae) Food reserve/storage material (2)
    -starch

    -lipids or oils (some) -helps them float
  11. (characteristics of algae) Reproduction (2)
    • -asexually
    • *fission: split in half
    • *fragmentation: in filaments

    • -sexual reproduction
    • *gametes: sex cells

    *egg and sperm (most)
  12. Isogamy
    equal sized gametes

    -mostly primitive
  13. Heterogramy
    different sized gametes, both swim
  14. Oogamy
    egg (larger doesnt swim) and sperm (smaller, swims)

    -most advanced like plants
  15. fission
    mitotic division of nuclear material followed by cytokinesis
  16. framentation
    splitting of colony into sections
  17. pyrenoid
    center of starch formation in some chlorplasts
  18. Zoospores
    mobile cell with flagella
  19. 3 main parts to kelp
    -holdfast (bottom)

    -stipe (stalk)

    -blade
  20. Cyanophyte (5) blue green/cyanobacteria
    • -prokayotic
    • -food reserves: glycogen reserves
    • - no sexual reproduction
    • - pigments: chl. A
    • -asexual rep.: fission and fragmentation
  21. Chlorophyta (4) green
    • pigments: chl. A, B; carotene and xentophyll
    • food reserve: starch and pyrenoid in some
    • asexual rep. zoosphores and fragmentation
    • sexual rep. Oogamy, heterogamy, isogamy
  22. Phaeophyta; brown (5)
    • pigments: chl. A, C ; carotene; fucoxanthin
    • morphological: stipe, holdfast, air bladders
    • food reserve: laminarrian and mannitol oils
    • asex. rep.: fragmentation
    • sex. rep.: Oogamy
    • ex_kelp
  23. Rhodophyta; red
    • Pigments: chl a, d ; carotene
    • morphological: non-mobile cells
    • food reserve: floridean starch
    • asex. rep.: fragmentation
    • sex. rep.: Oogamy
  24. Chrysophyta diatoms (6)
    • pigments: chl. a,c ; carotene, fucoxanthin
    • morpholigical: silica-cell wall, gliding movement
    • food reserve: leucosin
    • asex. rep: fission
    • sex. rep.: isogamy
    • ex) diatoms, plankton
