edition, All 26 Chapters
Species
Group sharing similar characteristics and genetics.
Viruses
Not classified in Whittaker's five kingdoms.
Fungi
Kingdom of non-photosynthetic organisms.
Helminths
Worms studied in parasitology.
Prokaryotes
Organisms existing for two billion years.
Eukaryotes
Organisms evolved after prokaryotes.
Infectious Disease
New diseases emerging every 25 years.
Sterile
Free of all life forms.
Microorganisms
Not all are parasites.
Control Group
Used to measure variable effects in experiments.
,Hypothesis
Tentative explanation for observed phenomena.
Taxonomic Hierarchy
Permanent classification of organisms.
Theory
Hypothesis supported by substantial evidence.
Domains
Three: Bacteria, Archaea, Eukarya.
Archaea
Live in extreme environments.
Photosynthesis
Microorganisms contribute minimally to atmospheric oxygen.
Pathogen
Microorganisms causing disease in humans.
Theories vs Hypotheses
Theories have more supporting evidence.
Decomposers
Microorganisms recycling nutrients from dead matter.
Prokaryotes
Single-celled organisms without a nucleus.
Eukaryotes
