All cells are composed of the same basic chemicals: carbohydrates, proteins, nucleic acids, minerals, fats and vitamins. They also all regulate the flow of nutrients and wastes that enter and leave the cell. All cells undergo and are the result of cell division.
Eukaryote means 'the true nucleus', which refers to the large nucleus containing the DNA inside of a membrane.
Eukaryotic cells include organisms such as fungi, green plants, animals and proctoctists. These types of cells and organisms appeared 2000 million years ago, and it is more than likely that they evolved from prokaryotic cells.
Prokaryote means 'before the nucleus', which means the DNA isn't contained inside of the membrane.
Prokaryotic cells have appeared in fossil records from 3500 million years ago and are made up of a variety of organisms known collectively as bacteria.
Prokaryotic cells are smaller and less complex than eukaryotic cells. Prokaryotic cells have no nuclear membrane; the nuclear membrane is a very
