Bacteria/Protist groups

• Escherichia coli: common inhabitants of intestines; rods (bacilli); some are pathogenic
• Rhizobium leguminosum: rods (bacilli); in root nodules, capable of nitrogen fixation; many in symbiosis with plants

• Bacillus: many pathogenic
• Bacillus subtilis
• Bacillus anthacis (anthrax)

• Spirillum: move in corkscrew fasion, some patheogenic
• Treponema: syphilis

Anabaena: endosymbionts; no chloroplasts, but possess chl a; heterocysts (for nitrogen fixation); may form colonies, reproduce by binary fission

• Proteobacteria
• Gram-Positive Bacteria
• Spirochetes
• Cyanobacteria

• The Amoebozoa (Rhizopoda)
• The Alveolata (Trypanosomes, Apicomplexa, Ciliata, Dinoflagellata)
• The Euglenophyta
• The Stramenopila (Bacillariophyta, Phaeophyta)
• The Chlorophyta

• Dinoflagellata
• Stremenopila (Bicillariophyta, Phaeophyta)
• Chlorophyta

Amoeba: move by pseodopoida, predators/svagengers; ecto and endoplasm, food vacuoles (by phagocytosis), intracellular digestion, contractile vacuoles

• Trypanosomes (Kinetoplastida)
• Apicomplexa
• Ciliata
• Dinoflagellata

Trypanosoma: sleeping sickness, bite from tsetse fly, extracellular parasite; undulating membrane

Plasmodium: malaria; intracellular parasites of red blood cells

Paramecium: cilia, pellicle, macro/micronucleus, oral groove --> cytostome, food vacuoles

Ceratium: grooves, red tide

Euglena: 2 different flagella, form paramylon starch, stigma (eyespot; next to anterior flagellum and acts as a photoreceptor/primitive eye), mixotrophic, reproduce by binary fission

Diatoms: chl a, "golden brown algae," paired and overlapping cell walls (silicon dioxide, calcium carbonates)

Kelps/seaweed/"brown algae": multicellular autotrophs; thallus, holdfasts, stipes, blades, air bladder floats

• Volvox: produce daughter colonies asexually (internal); form vegetative cells that have cytoplasmic connections between them; sexually produce by forming a zygospore
• Spirogyra: filamentous
