Because a eukaryotic cell’s nucleus is surrounded by a membrane, it is often said to have a “true nucleus.” The word “organelle” means “little organ,” and, as already mentioned, organelles have specialized cellular functions, just as the organs of your body have specialized functions.Īt this point, it should be clear to you that eukaryotic cells have a more complex structure than prokaryotic cells. Unlike prokaryotic cells, eukaryotic cells have: 1) a membrane-bound nucleus 2) numerous membrane-bound organelles such as the endoplasmic reticulum, Golgi apparatus, chloroplasts, mitochondria, and others and 3) several, rod-shaped chromosomes. Our natural world also utilizes the principle of form following function, especially in cell biology, and this will become clear as we explore eukaryotic cells ( Figure 1). For example, a skyscraper should be built with several elevator banks a hospital should be built so that its emergency room is easily accessible. In architecture, this means that buildings should be constructed to support the activities that will be carried out inside them. Have you ever heard the phrase “form follows function?” It’s a philosophy practiced in many industries.
