3 types of protists
1) animal like species (protozoa)
2) photosynthetic like species (algae)
3) fungus-like species (slime molds)
Mixotrophs
Protists with 2 modes of nutrition (photoautotroph and chemoheterotroph)
Characteristics of protists
-can be unicellular, colonial, or multicellular
-mobile using cilia and flagella
-can reproduce sexually and asexually
-some have complex cells
-most are free living, some are symbiotic
Eukaryotes have the following, prokaryotes do not
-mitochondria
-chloroplasts
-mitosis (cell division)
-meiosis (produces gametes)
-sex
-9 + 2 flagella
-cytoskeleton
Endosymbiosis
-origin of mitochondria and chloroplasts
-one type of bacteria started living in side others
Supergroup excavata

-unicellular flagellates
-often have a feeding groove
-many phagocytize their food
-ex) parasites (trichomonas vaginalis), metamonads (giardia lamblia, euglenoids,
kinetoplastids
Euglenoids
-supergroup excavata
-heterotrophs but some are photosynthetic
-ribbon-like protein strips below plasma membrane
Kinetoplastids
-supergroup excavata
-kinetoplasts (mass of extranuclear dna)
-includes trypansoma (african sleeping sickness)
Supergroup land plants and relatives
-red algae, green algae, plants, cryptomonads, haptophytes
-have plastids
Plastids
-organelles such as chloroplasts
-have 2 envelope membranes
Red algae
-supergroup land plants and relatives
-mostly red but not all
-most are marine and multicellular
-sushi wrap
-some can live deep but most don't
Green algae
-supergroup land plants and relatives
-mostly in freshwater
