- Both have DNA as their genetic material (it’s DNA that tells cells what kind of cells they should be).
- Both are covered by a cell membrane.
- Both contain RNA.
- Both are made from the same basic chemicals: carbohydrates, proteins, nucleic acid, minerals, fats and vitamins.
- Both have ribosomes (the structures on which proteins are made).
- Both regulate the flow of the nutrients and wastes that enter and leave them.
- Both have similar basic metabolism (life processes) like photosynthesis 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 environment around them.
