PROCARYOTIC CELL & EUCARYOTIC CELL have in common:
·Both have DNA as their genetic material.
·Both are covered by a cell membrane.
·Both contain RNA.
·Both are made from the same basical chemicals (carbohydrates, proteins, nucleic acid, minerals, fats and vitamins.
·Both have ribosomes.
·Both regulate the flow on the nutrients and wastes that enter and leave them.
·Both have similar basic metabolism (life processes) like photosyntesis and reproduction.
·Both require a supply of energy.
·Both are highly regulated by elaborate sensing systems ('chemical noses') that make them aware of the reactions within them and the enviroment around them.

ANOTHER DIFFERENCES.
Scientists belive that procaryotic cells (in the form of bacteria) were the first life forms on earth. They are considered 'primitive' and originated about 3.5 billion years ago. That's 2 billion years earlier than eucaryotic cells and billion of years before our earliest ancestors, the hominids.
·4.6 billion years ago the Earth was formed.
·3.5 billion years ago the first life arose: procaryotic bacteria
