How does a bacterial cell differ from a plants or animals cells?

Bacteria are among the most primitive organisms in the planet. Some bacteria can live with little or no oxygen. Bacteria are different from plant and animal cells in that they have no mitochondria or robosomes. They don't have a nucleus either. Because of this, most of their organelles that would be in the nucleus area in a plant or animal cell are just floating around in the bacterial cell. They also differ in their structure because they might include a flagellum (some bacteria have a whiplike tail to help it move), pili (hairlike structures that help them to attach to each other and to surfaces), and a capsule, which is a sticky coating surounding the bacteria, and makes it difficult for amnimals' white blood cells to destroy it.
