Show Answers:

  1. Cytosol
    Allows for the diffusion of molecules throughtout the cell
  2. Cytoskeleton
    Allows materials to be moved around inside the cell; provides a framework for anchoring other organelles

    Microfilaments, microtubules, intermediate filaments
  3. Microfilaments
    Involved in movement of materials within the cellular membrane and amoeboid movement
  4. Microtubules
    Involved in chromosomal separation during mitosis and meiosis; sturctural basis for cilia and flagella
  5. Intermediate Filaments
    Help maintain the overall integrity of the cytoskeleton
  6. Transport Proteins
    Allow polar (hydrophilic) molecules and ions to move in and out of the cell
  7. Cell Adhesion Molecules
    Proteins that allow cells to recognize each other and contribute to proper cell differentiation and development
  8. Nuclear Membrane/Envelope
    Maintains a nuclear environment separate and distinct from the cytoplasm
  9. Nuclear Pores
    Allow for the selective two-way exchange of material into and out of the nucleus
  10. Ribosomes
    Protein production
  11. Endoplasmic Reticulum
    Production and sorting of materials from the cell, especially those destined to be secreted
  12. Smooth ER
    Lipid synthesis and detoxification of drugs and poisons
  13. Rough ER
    Production of protein products
  14. Golgi Apparatus
    Receives materials from the smooth ER and repackages them to send to the cell surface
  15. Secretory Vesicles
    Vehicles that transport products from the golgi to the cell's exterior
  16. Vesicles and Vacuoles
    Transport and store materials that are ingested, secreted, processed, or digested by the cell
  17. Lysosomes
    Take material brought in by the endosomes and break down materials ingested by the cell; remove old cellular components and replace them with newer ones; can cause autolysis
  18. Mitochondria
    Outer Membrane: allows in the appropriate materials for respiration

    Inner Membrane: contains molecules and enzymes necessary for the ETC. Contains cristae (infoldings

    Semiautonomous: contain some of their own genes and replicate independently of the nucleus via binary fission
  19. Mitochondrial Matrix
    Contains many other enymes important in cellular respiration
  20. Microbodies
    Catalyze specific types of reactions by sequestering the necessary enzymes and substrates

    EX: Peroxisomes & Glyoxysomes
  21. Peroxisomes
    Create hydrogen peroxide within a cell; used to break down fats into usable molecules; catalyze detoxification reactions in the liver
  22. Glyoxysomes
    Convert fats to usable fuel
  23. Chloroplasts
    Generate energy through photosynthesis; contain their own DNA
  24. Cell Wall
    • Plants: Cellulose
    • Fungi: Chitin
    • Protisits: Calcium Carbonate
    • Animals: NO CELL WALL
  25. Centriole
    Organizes the spindle apparatus on which the chromosomes move during mitosis
