Six Kingdoms

• Archaebacteriablue green algae or cyanobacteria
• Eubacteriatrue bacteria
• Protista
• Fungi
• Plants
• Animalia

3

• Kingdom
• Phylum-----divisions
• Class
• Order
• Family
• Genus
• Species

4
Bacteria

• Heterotrophicmost are decomposers
• Autotrophic---photosynthetic or chemosynthetic
• No organelles
• Represent the smallest living organisms on earth
• Reproduce rapidly (about twice an hour)

5
Prokaryotic producers

• Cyanobacteria---blue green algae
• Can tolerate a huge change in salinity and
  temperature
• Some of these are nitrogen fixers

6
Protists

• Three types
• Plant like
• Animal like
• Fungus like

7
Plant like

• Diatoms
• Dinoflagellates
• Silicoflagellates
• There are more but we discuss these

8
Diatoms

• Eukaryotic
• Photosynthesize
• Reproduce sexually or asexual
• 12,000 species
• They have silica shells called frustules
• Called golden brown algae from the pigment
  carotenoid

9
Diatom reproduction

• Sexual
• asexual

10
dinoflegellates

• They have flagella
• They spin
• Unicellular
• They have a primitive eyespotsense light
• They can be seen in the light
• Cause algal bloomsred tide

11
Red tides
12
bioluminescence

• Produce light--

13
silicoflagellates

• Star shaped
• Have silica in their cell walls
• flagella

14
protozoans

• Animal like protists
• Euglena
• Amoeba
• paramecium

15
foraminiferans

• Phylum forminfera
• Mostly marine
• Shells of calcium carbonate
• Psuedopods can retract

16
foraminiferans

• Phylum radiolarians
• Round elaborate shells
• Made of silica
• Rotating spines

17
foraminiferans

• Phylum ciliophora

18
seaweeds

• Greendivision chlorophyta
• Browndivision phaeophyta
• Reddivision rhodophyta

Phaeophyta

• Padina
• Fucus spiralis
• kelp

22
