and answers 2024
Microorganism - Organisms too small to be seen by the naked eye
Less than 1mm
Unicellular
If multicellular thay lack different tissues
acellular microorganisms - viruses -protein and nucleic acid,
viroids - RNA
satellites -nucleic acid with a protein shell
prions- protein
Cellular microorganisms - fungi - yeast molds
protists - algae, Protozoa, slime molds
bacteria -E Coli
archaea - methanogens (natural gas)extreme environments

organelles.
, Microbiology StraighterLine unit 1 questions
and answers 2024
Eukaryotic cells - Contain a nucleus and other organelles that are bound by
membranes.
Carl Woese - Devised a system of classification based on the cellular organization
of organisms (bacteria and archaea)
Protista Kingdom - Single cell, microscopic organisms, EUkaryotic cells
Bacteria - Can be pathogens (Black Plague)
Human biome
Break down dead animal and plant cells
Used to make bread cheese antibiotics vitamins and enzymes
Bacteria are abundant where - Extreme sites of temperature PH and salinity.
Major part of human microbiome
Domain Archaea - One of the three domains of life; contains prokaryotic cells that
often live in extreme habitats and have unique genetic, biochemical, and
physiological characteristics; its members are sometimes referred to as archaea.
