Animal cell, cutaway artwork. The cell membrane (green) surrounds internal structures(organelles) that include the nucleus (purple), which contains the nucleolus (sphere, lower centre). The nucleus contains theDNA ( deoxyribonucleic acid ) that controlsprotein synthesis on ribosomes (chains ofsmall yellow spheres) in the rough ER( endoplasmic reticulum, membrane folds, above and at right of nucleus). The proteins arestored in the flattened membranes of the Golgi complex (above and at right of rough ER).Energy is generated by mitochondria (cylinders, one at bottom centre). Cells are themicroscopic structural and functional units of allliving organisms. See B060/063 for a plant cell.
