· Search what procaryotic and Eukariotic ceells eucaryotic cel have in common.
-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.

·What are the differences?
Eukaryotic cells have a true nucleus, bound by a double membrane.
Eukaryotic DNA is linear; prokaryotic DNA is circular (it has no ends).
Eukaryotic DNA is complexed with proteins called "histones," and is organized into chromosomes; prokaryotic DNA is "naked," meaning that it has no histones associated with it, and it is not formed into chromosomes.
Both cell types have many, many ribosomes, but the ribosomes of the eukaryotic cells are larger and more complex than those of the prokaryotic cell.
The cytoplasm of eukaryotic cells is filled with a large, complex collection of organelles, many of them enclosed in their own membranes; the prokaryotic cell contains no membrane-bound organelles which are independent of the plasma membrane.
