Ribosomes: Found floating free in the cytoplasm or attached to the surface of the rough endoplasmic reticulum and also in the mitochondria and chloroplast. They are the site of protein synthesis.
Rough endoplasmic reticulum: Can modify proteins to alter their function and/or destination. Synthesizes proteins to be excreted from the cell.
Lysosome: Contains digestive enzymes to hydrolyze macromolecules such as proteins and lipids into their monomers.
Golgi apparatus: Receives proteins from the rough endoplasmic reticulum and may further modify them. It also packages proteins before the protein is sent to it’s final destination which may be intracellular or extracellular.
Mitochondria: Is responsible for aerobic respiration. It converts chemical energy into ATP using oxygen.
Nucleus: Contains the chromosomes and therefore the hereditary material. The nucleus is responsible for controlling the cell.
Vacuole: They are for intracellular secretion, excretion, storage, and digestion.
Centrosomes: An area in the cell where microtubles are produced.
Plasma Membrane: Semi-permeable membrane that controls the substances moving into and out of the cell. Substances are able to pass through it by either active or passive transport.
