Classification of Microorganisms Made by Mukhamejan R.
Taxonomy is the practice and science of classification. A taxonomy, or taxonomic scheme, is a particular classification. The word finds its roots in the Greek τάξις, taxis (meaning 'order', 'arrangement') and νόμος, nomos ('law' or 'science'). Originally taxonomy referred only to the classifying of organisms or a particular classification of organisms
Microbiology • From Greek μῑκρος, mīkros, "small” • βίος, bios, "life" • -λογία, -logia , study • Microbiology is the study of microscopic organisms, either – unicellular (single cell), – multicellular (cell colony), or – acellular (lacking cells) • Microbiology encompasses numerous sub-disciplines including : virology, mycology, parasitology, and bacteriology
Taxonomic arrangement Bacteriology: The study of bacteria. • • Prokaryotes Peptidoglycan cell walls Binary fission For energy, use organic chemicals, inorganic chemicals, or photosynthesis
Mycology: The study of fungi. • • Eukaryotes Chitin cell walls Use organic chemicals for energy Yeasts are unicellular
Protozoology: The study of protozoa. • Eukaryotes • Absorb or ingest organic chemicals • May be motile via pseudopods, cilia, or flagella • Most free some parasites
Phycology (or algology): The study of algae • Eukaryotes • Cellulose cell walls • Use photosynthesis for energy (primary producers) • Produce molecular oxygen and organic compounds • Metabolically diverse
Parasitology: The study of parasites. • Eukaryote • Multicellular animals • Parasitic flatworms and round worms are called helminths. • Microscopic stages in life cycles.
Virology: The study of viruses. • • • Acellular Consist of DNA or RNA core Core is surrounded by a protein coat Coat may be enclosed in a lipid envelope Viruses are replicated only when they are in a living host cell
Immunology: The study of the immune system. • Immunology is a branch of biomedical science that covers the study of all aspects of the immune system in all organisms. Nematology: The study of the nematodes
