  1. What are threadlike structures built of DNA and protein that condenses and becomes visible in a cell’s nucleus during mitosis?
    Chromosomes
  2. Organic molecule that stores and transfers energy, also used in cellular process?
    ATP
  3. These are tiny, hair like structures that wave, moving fluids across cell surfaces.
    Cilia
  4. Cellular structure built of microtubules that organizes the mitotic spindle?
    Centrioles
  5. Cellular organelle consisting of two centrioles?
    Centrosome
  6. Organelle that is located in cytoplasm near nucleus and consists of 2 centrioles (2 cylinders)?
    Centrosome
  7. Threadlike structure built of DNA and protein that condenses and becomes visible in a cell’s nucleus during mitosis?
    Chromosome
  8. System of protein tubules and filaments reinforces a cells 3-D form, provides scaffolding and transport pathways for organelles?
    Cytoskeleton
  9. Relatively long, motile process that extends from the surface of a sperm cell?
    Flagella
  10. What is an organelle that prepares cellular products for secretion?
    Golgi Apparatus
  11. Stack of half a dozen or so flattened membranous sacs (cisternae). This organelle refines, packages and delivers proteins synthesized on the rough ER.
    Golgi apparatus
  12. This is an organelle that contains digestive enzymes?
    Lysosome
  13. These are the garbage disposals of a cell. They also breakdown proteins, carbohydrates and nucleic acids?
    Lysosomes
  14. Rod of protein actin; part of the cytoskeleton?
    Microfilament
  15. Hollow rod of the protein tubulin; part of the cytoskeleton?
    Microtubule
  16. Elongated fluid filled sacs. Found in cytoplasm and can divide. Also contains small amount of DNA –that encodes information for making a few types of proteins and specialized RNA.
    Mitochondria
  17. Organelle housing enzymes that catalyze aerobic reactions of cellular respiration?
    Mitochondrion
  18. Any of the thread-like bundles of filaments in muscle cells?
    Myofibrils
  19. Membranous cytoplasmic vesicle that contains enzymes that catalyze reactions that produce and decompose hydrogen peroxide?
    Peroxisomes
  20. Are tiny, spherical structures composed of protein and RNA. They provide a structural support and enzymatic activity to link amino acids to form proteins.
    Ribosomes
  21. Studded with many ribosomes and sites of protein synthesis?
    Rough ER
  22. Outer membranous surface is studded with ribosomes, also the sight of protein synthesis.
    Rough ER
  23. The outer membranous surface of some ER is studded with many ribosomes that give the ER a textured appearance when viewed with an electron microscope is called?
    Rough ER
  24. What are membranous sacs that store or transport substances within a cell. They vary in size and contents?
    Vesicles
