Abstract

Cells are living entities made up of a central nuclear region which contains the hereditary material, surrounded on all sides by cytoplasm, which, encompassed by a delimiting membrane, contains all the structures required for biological processes, such as making protein and extracting utilizable energy from food. These events may occur in separate compartments, the organelles, which include the endoplasmic reticulum, the Golgi apparatus, the mitochondria, the chloroplasts and the lysosomes; there is also an internal cytoskeleton.
