Protists- Protozoa & Slime Molds

First animal; Eukaryotes w/ an animal like heterotrophic ecology (not photosynthetic); have food and contractile vacuoles

Example: Amoeba + Difflugia
Key Characteristics: Move by pseudopodia
Common name: Amoebas

Example: Forams
Key Characteristics: Rigid shells; move by protoplasmic streaming

Example: Trypanosoma
Key Characteristics: Heterotrophic; unicellular
Common name: Flagellates
Have at least one flagellum
parasitic/ free living heterotrophs

Example: Paramecium, Vorticella
Key Characteristics: Heterotrophic unicellular protists w/ cells of fixed shape possessing 2 nuclei (micronuclei and macronuclei) and many cilia; many cells also contain highly complex and specialized organelles
Common name: Ciliates

Example: Plasmodium
Key Characteristics: Nonmotile; unicellular; the apical end of the spores contains a complex mass of organelles
Common name: Sporozoans

Example: Water molds, rusts, mildew
Key Characteristics: Terrestrial and freshwater
Common name: water molds

Example: Dictyostelium
Key Characteristics: Colonial aggregations of individual cells; most closely related to amoebas
Common name: Cellular slime molds

Example: Physarum
Key Characteristics: Stream along as a multinucleate mass of cytoplasm
Common name: Plasmodial slime molds

Movable extensions of cytoplasm used for locomotion and gathering food

Phylum: Rhizopoda
Have pseudopods
polyphyletic
phagocytic
intracellular digestion

Phylum: Rhizopoda
Have psuedopods
Have tests ( a secreted or partially secreted covering, much like a shell)

Phylum: Foraminifera
Shelled amoebas (secreted test)
Test made of calcium carbonate w/ pores
used by oil companies to locate oil

Phylum: Kinetoplastia
Pathogenic
Cause African Sleeping Sickness + Chagas disease
Surrounds the red blood cell sin the plasma
Have undulating membranes for locomotion
spread by mosquitoes and flies

Phylum: Ciliophora
Sexual process: Conjugation
Asexual Reproduction: transverse fission

Phylum: Ciliophora
Sessile (attached to a substrate)
2 features: Contractile stalk + cell body w/ a corona of cilia
Filter feeding

Phylum: Apicomplexa
Causes malaria
Most common killer of humans in history
transferred by mosquitoes
infect inside the red blood cells

Phylum: Dictyostelia
Stream along the damp forest floor in a mass of brightly colored protoplasm called plasmodium
Plasmodia are coenocytic (multinucleate)
Sclerotium: when environment i bad, can dry into a hard structure called sclerotium
Forms sporangia to reproduce: Syngamy
