4). While prokaryotes are single-celled, most eukaryotes are multi-celled which influences the cells mobility and defines their function. The simplicity and specialization of the prokaryotic cells and the complexity of the multi-celled structure of the eukaryotic cells limit and allow for the unique functions of each classification.
The simplicity of the prokaryotic cell gives it an independence and mobility that most eukaryotic cells do not possess. Prokaryotic cells are the building blocks of our immune system and have the ability to attack foreign life forms that invade their sphere. They form the bacteria in our intestines that provide necessary vitamins as well as preventing the growth of harmful fungus within our body. Prokaryotic cells are located almost everywhere in nature and are continually in the process of decomposing and recycling dead organisms (Campbell and Reece, 527). This process returns the basic chemical elements back to the earth, which will be used to fertilize plants and feed animals. It is the simplicity of the parkaryotic cell that gives it the diversity and flexibility to support the eukaryotic cells.
Eukaryotic cells are typically multi-celled organisms that have a complex DNA structure that has evolved from prokaryotic cells.
