Eukaryotes and Prokaryotes
Life can be divided up into three domains; Eukaryotes, Bacteria and Archaea. The Eukaryotes includes all animals, plants, fungi and protista. The Bacteria and Archaea can be grouped together as the Prokaryotes.
Bacterial cells are an example of a prokaryote. They are much smaller than eukaryotic cells. They contain a cytoplasm and a cell membrane surrounded by a cell wall. The main difference is that their genetic material is not enclosed in a nucleus, but can be found as a single DNA loop. There may also be one or more smaller rings of DNA called plasmids.
Plant and animal cells are eukaryotic cells. They all contain a cell membrane, cytoplasm and have their genetic material enclosed in a nucleus.
