The two types of cells that exist in nature are prokaryotic and eukaryotic cells. Plant and animal cells both belong to the eukaryotic group of cells, which contain many membrane-bound organelles (small structures within cells that perform dedicated functions).
As the name implies, organelles are small organs. There are a dozen different types of organelles commonly found in eukaryotic cells, for example, mitochondria, Golgi bodies and the nucleus.
The word “prokaryotes” (also spelt “procaryotes”) comes from two Greek words pro (before), and karyon (nut or kernel). It is used to describe unicellular (single-celled) organisms that lack a true nucleus and membrane-bound cell organelles. This means that the genetic material in prokaryotes is not bound within a nucleus. Bacteria and archaea belong to such groups.
