    Cell organelles Cell organelles Presentation Transcript

    • Cell Membrane
      • Outer boundary of cell
      • Protects the cell
      • Controls what enters and leaves the cell
    • Cell Wall
      • Only found in plant cells
      • Adds protection and support
      • Made of cellulose.
      • Allows water and dissolved substances to pass through.
    • The Nucleus
      • Controls most activities in the cell
      • Contains all genetic information in the form of DNA.
    • Cytoplasm
      • Clear fluid within cell that contains all organelles
      • Moves materials throughout the cell
    • Endoplasmic Reticulum
      • Series of folded membranes that form sacs or tubes
      • Rough ER has ribosomes attached
    • Ribosomes
      • Transports materials between the cytoplasm and nucleus
      • Makes proteins in the cell
      • May be free in cytoplasm or attached to ER
      • Proteins are vital to life- all cells must produce them
    • Golgi Bodies
      • Saclike membranes used for storing/ packaging of chemicals
      • Cells that make saliva or mucus have many Golgi bodies
    • Mitochondria
      • Energy producers
      • Powerhouse of the cell
      • Sausage-shaped
      • Many mitochondria in muscle cells
    • Plastids
      • Only found in plants/ algae
      • Contain food or pigments
      • Leucoplasts store food
      • Chloroplasts contain the pigment chlorophyll
    • Vacuoles
      • Store food, water, or waste materials
      • Plant cells have large vacuoles
    • Lysosomes
      • Found in Golgi bodies
      • Contain digestive enzymes to digest unwanted particles
      • Help white blood cells to destroy bacteria
