This is the domain whose cell walls contain peptidoglycan.
Hair-like structures made of protein that help bacteria attach to surfaces.
Division of a cell into two genetically identical cells.
Unicellular organisms with no nucleus or organelles
The kingdom Monera is now divided into what two domains?
Bacteria and Archaea
The chemical substance that protects bacterial cell walls from injury
Archaea are sometimes called these
These live in hot, acidic environments and many are anaerobes
These live in very salty environments and are usually aerobic
These produce methane gas as a waste product and are obligate anaerobes
Most prokaryotes have a smaller piece of circular DNA called this
In prokaryotes, chromosomes are found in an area of the cell called this
Some prokaryotes secrete a layer around the cell wall forming this; it prevents the cell from drying out and helps it attach to surfaces
Submicroscipic hair-like structures that serves as a bridge between cells
Most prokaryotes reproduce by this method
Some prokaryotes attach to each other by pili and exchange genetic information this way
Can't live or grow in the presence of oxygen
Can grow with or without oxygen
Require oxygen to grow and live
