Bacterial cell walls contain a protein called peptidoglycan, a compound which archaea lack.

When comparing the genomes of bacteria and archaea, scientists found differences in their RNA Sequences.

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.

Spherical bacterial cells are called cocci.

Rod-shaped bacterial cells are called bacilli.

Autotrophs (self-feeders) make organic compounds from inorganic sources.

Cyanobacteria are bacteria that perform photosynthesis.

chemoautotrophs

The first prokaryotes on the planet were likely chemoautotrophs.

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 are little noodle things are cover certain prokaryotes and allow them to stick to surfaces.

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 are prokaryotes with many spread out filaments that hold together small clumps of soil.

Extreme Halophiles thrive in salty places.
