These can be a danger to human and animal health, as certain protists can cause diseases, such as malaria and sleeping sickness.hey reproduce by first copying their DNA and than performing cell division. Bacteria also lack membrane-bound organelles, such as mitochondria, the cell structures involved in energy metabolism. Bacterial cells are so small that scientists measure them in units called micrometers (Âµm), a millionth of a meter.
