Presentation on theme: "Structure and function are related!"— Presentation transcript:
1 Structure and function are related! Big theme in biology:Structure and function are related!This is true at all levels of organization: at the levels of molecules, organelles, cells, tissues, organs, and organisms.1
10 Organelle (part) Function (job) Cell Organelles in CytoplasmOrganelle (part)Function (job)Mitochondria“powerhouse” converts food energy in to usable energy (ATP)ERCarries proteins throughout the cell.RibosomesMakes proteinsGolgi BodiesReceives, packages & sends materials.Chloroplasts(plant only)Captures light energy to make food energyVacuolesstorageLysosomesChemicals for breakdown.
