• Eukaryotic cells are smaller than prokaryotic cells.

• Prokaryotic cells are more complex than eukaryotic cells.

• Prokaryotic cells contain a distinct central organelle, and eukaryotic cells do not.

Bacteria are single-celled microorganisms. The cell walls of these microorganisms serve as barriers to chemicals that might affect the processes that occur within a bacterial cell. Antibiotics are a type of substance used to stop bacterial growth. Some antibiotics cause the bacterial cell wall to rupture. The function of which human organ is most like the cell walls of bacteria? 

• heart

• liver

• pancreas

• skin
