introduction and history of microbio

  1. what are the 3 characteristics of microorganism?
    • movement: fast or slow
    • reproduction: either sexual or asexual
    • mutation: changing of genetic code in response to environment
    • *require food to function and waste to be excreted
  2. eukaryotic vs prokaryotic
    • eukaryotic: contains nucleus, protoplast, cytoplast and membrane composed of phospholipids. ex) fungi, yeast, helminth
    • prokaryotic: contains DNA molecules without nucleus. ex) bacteria, cyanobacteria
  3. what are the types of bacteria
    • mutualist/beneficial: benefits us, necessary for our survival
    • commensalist:¬†uses us w/o harming us. ex) oral cavity
    • parasitic: uses us and harms us, problematic
    • opportunistic: commensal, but when immunocompromised will become parasitic
  4. what are the groups of microorganisms
    • prokaryotic
    • eukaryotic
    • noncellular: no cytoplast, no cytoplasm. ex) viruses with either DNA or RNA in nucleus, enclosed by capsule
  5. catabolism vs anabolism
    • catabolism: breaking large molecule into monomers
    • anabolism: producing large molecules from smaller molecules. Ex) yeast metabolizing glucose
  6. 2 categories of microorganisms when taking in matter
    • photoautotroph "self feeder": plants, cyanobacteria
    • hetertroph "other feeder": usually lipase positve or lactose positive. takes in fat
