Cell Organelles And their definitions and pretty pictures too. Mr. Snider SOCES Cell Membrane • Protects cell • Controls what goes in and out • Semi-permeable membrane DNA • Genetic information • Sections control what proteins to make • 2 strands • Deoxyribonucleic acid DNA RNA • Carries messages • Single strand • Ribonucleic Acid RNA Ribosome • Makes Proteins • Free in cell or attached to Rough Endoplasmic Reticulum Cytoplasm • Support, structure • Stores raw material • Some chemical reactions • Separates organelles Cell Wall • Protection, support outside cell • Not found in all organisms Endoplasmic Reticulum • Passageway through cell • Rough – w/Ribosomes finish protein • Smooth – makes lipids Golgi Body • Package and ship protein out of cell Nucleus • Contains DNA • Controls cell Nucleolus • Makes ribosomes Mitochondria • Turns sugar into ATP Chloroplast • Turns sunlight into sugar • Only found in plants* Vacuole • Holds material Lysosome • Breaks down/digests materials • Found in Animal cells Cytoskeleton • Structure, support, movement Cytoskeleton Cytoskeleton Centriole • Cell reproduction – Mitosis, Meiosis • Only in Animal cells
