Lysosome Sac filled with digestive enzymes. Breaks down and recycles old cell parts.
Centrioles A pair of tube-like structures that are perpendicular to each other. Important for cell division.
Mitochondria Powerhouse of the cell. Glucose (sugar) is "burnt" in the presence of oxygen to give the cell energy (respiration).
