Everything You'll Have Covered

What is the purpose of a bacterial cell wall?

~ The cell wall of bacteria gives shape and strength to the cell. It also prevents bursting in case excess water is absorbed by the cell.

What part of the cell is located just inside the cell wall, and what is its purpose?

~ The cell membrane is located inside the cell wall and controls the flow of materials entering and exiting the cell. In some bacteria, the cell membrane forms extensions called pili.

How do bacteria cells differ from eukaryotic cells?

~ Eukaryotic cells have a nucleus and membrane-enclosed organelles and bacteria do not.

How are bacteria and eukaryotic cells alike?

~ Both bacteria and eukaryotic cells have ribosomes. They both also have a cell membrane and cytoplasm.

What are plasmids?

~ Plasmids are small strands of circular DNA that contain a few genes, and can be found in bacteria.
