Bacteria

How are bacteria cells different from the cells of eukaryotes?

• Bacterias are prokaryotes

• Their genetic material is not contained within the nuclei.

• Eukaryotes have their genetic material in the nuclei

• Their genetic material is contained within the nuclei.

Four ways that bacteria are helpful to people.

• Provide oxygen, food products, environmental recycling, medicine.

• Provide carbon dioxide, food products, environmental recycling, medicine.

• Provide oxygen, waste products, environmental recycling, medicine.

• Provide oxygen, food products, environmental recycling.
