• Cell membrane: the boundary of an animal cell which regulates the moment of materials in and out of the cell

• Cytoplasm: clear, thick protoplasm that fills the space between the cell membrane and nucleus; suspends the organelles

• Nucleus: contains proteins, enzymes, and hereditary material; considered the control center of the cell

• Mitochondria: considered the powerhouse of the cell through the oxidation (breakdown) of sugars

• Centrioles: each cell has two, necessary for cell reproduction

• Endoplasmic reticulum (smooth): contains many enzymes necessary for cell metabolism (breaking down of foods and building cell substances)

• Endoplasmic reticulum (rough): protein production and transportation of protein throughout the cell

• Lysosomes: contains enzymes for food digestion

• Golgi Apparatus: packages large groups of protein molecules into vesicles

Vacuoles: store food, enzymes, and other materials; also, a temporary dumping place for waste products

• Ribosomes: small organelles of protein production
