Quick Answer

Bacteria cells do have organelles, although generally these are fewer in number and less complicated than those found in plants and animals. Most commonly, bacteria contain ribosomes. These organelles are composed of RNA-rich granules located within the cytoplasm and are the site for protein synthesis.

Full Answer

Bacteria cells are composed differently than those of plants and animals. They lack a nucleus and most other membrane-bound organelles, except for ribosomes. The bacterial cell has a basal body that allows it to rotate, and most have a membrane on the outside of the cell wall. Bacterial cells contain DNA located in the cytoplasm.

Other organelles may include the flagellum and pili. The flagellum of the bacterium is used for movement. Pili allow bacteria to transfer DNA and to stick to surfaces.
