chapter 1 Flashcards
6 types of microbes
-bacteria
-fungi
-algae
-virus
-protozoa
-helminths
prokaryote
-2 domains, some pathogens
-no membrane organelles
-no nucleus
-open concept house
eukaryote
-protists (kingdom)
-algae (photo synth, aquatic, science of phycology)
-protozoa (single cell, may be pathogenic, science is protozoology)
-fungi (decomposers, single or multicellular, mycology)
-helminths (worms)
-UNICELLULAR OR MULTICELLULAR
-ENCAPSULATES DNA
anthropods
not microbe
-cause and transmit disease
virsus
-acellular
-intracellular growth
-relatives: viroids, prions (infectious misfolded proteins that misfold other proteins)
-replicate in a host cell
virus structure
-capsid
-nucleic acid
-PROTEINS
endosymbiotic theory
-microbes form symbiotic relationship and that created eukaryotes
photosynth
light fueles conversion of co2 to organic material/ simple sugars which are the basis of the food web
bioremediation
living organisms to remedy environmental problem ex: oil spills
pathogen
microbe that harms
spontaneous generation
-life comes from nothing like sins or bad smells
pasteur
theory of biogenesis (living things come from other living things)
-found cause of fermentation and spoilage
-pasturization
-example of germ theory of disease
pasteur experiment
use sterile liquid with broken neck flask
-microbes grew when the flask was contaminated by air and not when it was closed
disproves spontaneous generation
-pastuer
-leeuwenhoek (observed sperm with microscope) (crude microscope)
tyndall and cohn
heat resistant microbes
-endospores
sterility
-eliminate all forms of life including virus and endospores
germ theory
disease are caused by microbe growth
-pasteur and koch
koch’s postulates
experimental steps that verified the germ theory
-found cause of anthrax, tb, cholera
-develop pure culture methods
four postulates
-microbe must be found in abundance in a diseased organism
-microorganism has to be isolated form the diseased and grown in a culture
-cultures microbe shouls cause disease in helathy orgnaism
-microbe reisolated from the inoculated, sick host and identified as identical to original agent
taxonomy
-organize, classify and name living things
classification levels
-domain
-kingdom
-phylum/ division
-class
-order
-family
-genus
-species
domain
-archaea, bacteria, eukarya
microbe 2 names
-genus (capitalized)
-species (lowercase)
-get italicized or underlined
phylogency
-natural relatedness between groups of organisms
evolution
-all new species orginate from preexisting species
-progresses towards greater complexity
