AP Bio chapter test 2

  1. Flagellum
    Motility structure in animal cell only
  2. Centrosome
    Region where the cell's microtubules are initiated
  3. Cytoskeleton
    reinforces cell's shape; functions in cell movement (includes microfilaments, Intermediate filaments, microtubules) made of protein
  4. Microvilli
    projections that increase the cell's surface area
  5. Peroxisome
    Organelle with various specialized metabolic functions; produces hydrogen then convers to water
  6. Mitochondrion
    Organelle where cellular respiration occurs and most ATP is generated
  7. Lysosome
    Digestive organelle where macromolecules are hydrolyzed
  8. Golgi apparatus
    organelle active is synthesis, modification, sorting, and secretion of cell products
  9. Ribosomes
    complexes that make proteins; free in cytosol or bound to rough ER or nuclear envelope
  10. Plasma membrane
    membrane, enclosing the cell; regulates permeability
  11. Nucleus, Nuclear envelope
    double membrane enclosing the nucleus; continuous with ER
  12. Nucleus, Nucleolus
    Nonmembranous structure involved in production of ribosomes; a nucleus has one or more nucleoli
  13. Nucleus, Chromatin
    Material consisting of DNA and proteins; visible in a dividing cell as individual condensed chromosomes
  14. Endoplasmic Reticulum (ER)
    Network of membranous sacs and tubes; active in membrane syntheses and other synthetic and metabolic processes
  15. Central vacuole
    Prominent organelle in older plant cells; storage and breakdown of waste products
  16. Chloroplasts
    Photosynthetic organelle; converts energy of sunlight to chemical energy stored in sugar molecules
  17. Plasmodesmata
    Cytoplasmic channels through cell walls that connect the cytoplasm of adjacent cells
  18. Cell wall
    outer layer that maintains cell's shape and protects cell from mechanical damage
