Cell Organelles Today you IDENTIFY the STRUCTURE and FUNCTION of cell organelles by correctly completing the chart!!! Cell Membrane •Located around the cell •Protects the cell and controls what AKA: enters or leaves the cell “Plasma Membrane” •Is “semipermeable” & Nucleus •Located in center of cell •Contains genetic material •Controls all of the cell’s processes & Inside the Nucleus • Nuclear Membrane: surrounds the nucleus • Nucleolus: dark spot that makes ribosomes • DNA: Genetic Material • Chromatin: Spread out DNA & protein • Chromosomes: Organized DNA/Protein The Nucleus!!! Endoplasmic Reticulum (ER) • Located in cytoplasm • Transports materials around cell • May be “Smooth” or “Rough”—rough has ribosomes & Ribosomes •Located on Rough ER •Make proteins & Mitochondria •Located in cytoplasm •Powerhouse of cell---cell respiration occurs here (sugar made into ATP) & Lysosomes •Located in cytoplasm •Digest and “get rid of” waste materials or foreign objects in the cell & Golgi •Located in cytoplasm •Package and “ship” proteins and other materials & Microtubules •Found in the cytoplasm • Hollow tubes that help the cell with many functions like moving around organelles. & Microfilaments •Found in the cytoplasm •Form the cytoskeleton, the internal frame of the cell & Centrioles •Located in cytoplasm •Help during cell reproduction ONLY Vacuoles •Located in cytoplasm •Sac-like structures that store water, nutrients and wastes •Plants have a large CENTRAL VACUOLE that gives the plant cell support & Cell Wall •Located outside of cell membrane •Gives plant cell structure •Made of cellulose Plastids •A general name for double membrane vessels in plant cells that carry out different functions Chloroplasts •Found in the cytoplasm •Absorb light energy for photosynthesis Leucoplasts •Colorless plastid that makes starch in plant cells Flagella •Located outside of cell •Long, tail-like structure that moves the cell or pushes things past the cell & Cilia •Located outside of cell •Many tiny bristle-like structures that move the cell or push things past the cell &
