    Study Notes

    Organelles Involved in Material Transport

    • Nucleus: The "brain" of the cell, it contains DNA and controls cellular activities
    • Nucleolus: Found inside the nucleus, synthesizes ribosomes
    • Cell Membrane: Outer layer of the cell, controls what enters and leaves
    • Mitochondria: "Powerhouse" of the cell, responsible for energy production
    • Ribosomes: Small structures that manufacture proteins
    • Lysosomes: "Recycling centers" that break down waste materials
    • Vesicles: Small, membrane-bound sacs that transport materials within the cell
    • Golgi Apparatus: Processes and packages proteins into vesicles
    • Rough Endoplasmic Reticulum: Produces proteins, often with ribosomes attached to its surface
    • Smooth Endoplasmic Reticulum: Produces lipids and detoxifies substances
    • Chloroplasts: (plant cells only) Sites of photosynthesis
    • Cell Wall: (plant cells only) Provides structural support and protection
    • Central Vacuole: (plant cells only) Large storage container for water and nutrients

    Ribosomes

    • Are not surrounded by a membrane
    • Synthesize proteins
    • Proteins are made from amino acids

    Endoplasmic Reticulum (ER)

    • A web-like network that extends throughout the cytoplasm
    • Rough ER: Ribosomes attached to its surface produce proteins
    • Smooth ER: No ribosomes, involved in lipid production and detoxification

    Vacuoles

    • Sac-like structures that store food, water, and waste
    • Plant cells usually have a large central vacuole
    • Animal cells may have multiple, smaller vacuoles

    The Golgi Apparatus

    • Prepares proteins for their specific functions
    • Packages proteins into vesicles

    Three-Dimensional Thinking

    • Graphic Organizer: Shows how organelles work together
    • Steps of protein production, modification, and transport:
      • Ribosomes make proteins
      • Proteins are modified in the Rough ER
      • Proteins are transported to the Smooth ER, which removes harmful substances
      • Vesicles transport proteins to the Golgi Apparatus, where they are packaged and further modified
      • Vesicles transport proteins to their final destination within the cell
