    • bacteria are very small and can only be seen with a powerful microscope
    • bacterial cells have a cell membrane and a cell wall which surround cytoplasm
    • bacteria do not have a nucleus so the genetic material is in the cytoplasm
    • when bacteria multiply they form a colony. Bacterial colonies can be seen with the naked eye
