The both do have DNA for genetic material, have a exterior membrane, have ribosomes, accomplish similar functions, and are very diverse. For instance, there are over 200 types of cells in the human body, that very greatly in size, shape, and function.
Prokaryotes are cells without a nucleus.
They have genetic materials but are not enclosed within a membrane. These include bacteria and cyanophytes. The genetic material is a single circular DNA and is contained in the cytoplasm, since there is no nucleus. They do not engulf solids nor do they have centrioles or asters. There are pictures of 2 prokaryotes below.
