Prokaryotes and More Immune System

Terms in this set (26)

peptidoglycan
Bacterial cell walls contain a protein called peptidoglycan, a compound which archaea lack.
RNA Sequences
When comparing the genomes of bacteria and archaea, scientists found differences in their RNA Sequences.
Eukaryotes
When comparing the three domains, archaea appear to be more similar to Eukaryotes.
spheres, rods, or circles
Bacteria can be shaped like spheres, rods, or circles.
Cocci
Spherical bacterial cells are called cocci.
Bacilli
Rod-shaped bacterial cells are called bacilli.
Autotrophs
Autotrophs (self-feeders) make organic compounds from inorganic sources.
Cyanobacteria
Cyanobacteria are bacteria that perform photosynthesis.
chemoautotrophs
The first prokaryotes on the planet were likely chemoautotrophs.
Methanogens
Methanogens are prokaryotes that produce methane as a waste product. They are found in swamps and animals' digestive tracts.
Prokaryotic Flagellum
A prokaryotic flagellum is a rotating noodle thing that helps prokaryotes to move about.
Pili
Pili are little noodle things are cover certain prokaryotes and allow them to stick to surfaces.
Endospore
An endospore is like an emergency pod for a prokaryote. If the rest of the cell dies, it remains dormant until a more hospitable home is found, and then it grows into a full cell.
Actinomycetes
Actinomycetes are prokaryotes with many spread out filaments that hold together small clumps of soil.
Halophiles
Extreme Halophiles thrive in salty places.
