INTRO TO MICROPARA

specialized area of biology that deals with organisms too small to be seen without magnification

the study of parasites, their hosts, and the relationship between them

give me the 7 microorganisms

• Prokaryotic  Cell wall with peptidoglycan (most)  Unicellular  Reproduce by binary fission (asexually)  Circular DNA  Some are autotrophic, some are heterotrophic

 Prokaryotic  Cell wall lacks peptidoglycan  Unicellular  Reproduce by binary fission (asexually)  Extremophiles  Thermophiles , Halophiles , Methanogens

WHAT ARE THE 3 EXTREMOPHILES

 Eukaryotic  Lacks cell walls  Usually heterotrophic  Unicellular  Can reproduce asexually and sexually  Moves by: Pseudopods , Flagella , Cilia , Some are non -motile

PROTOZOA MOVES BY:

 Eukaryotic  Cell wall has chitin  Heterotrophic  Unicellular (yeast) or multicellular (molds and mushroom)  Can reproduce asexually and sexually  Linear DNA

 Flatworms and roundworms  No cell wall  Heterotrophic  Can reproduce sexually and asexually  Have microscopic stages

 Acellular  Obligate intracellular parasite  DNA or RNA  May be enveloped or naked  A capsid (protein coat) is required

 Eukaryotic  Cell wall has cellulose  Photosynthetic  Unicellular or multicellular  Can reproduce sexually or asexually  Often contains pigments: green , red, or brown
