Janessa Sorrells Reviewing Your Knowledge Exercise 4 A. Cellular Structure Fill in the blank with the name of the cell structure that fits the description. Cilia 1. short, hair-like projections for movement of substances along cell surface Cytosol2. intracellular fluid Mitochondria3. site of energy production by cellular respiration Ribosomes4. site of protein synthesis Smooth ER5. site of steroid and fatty acid synthesis Lysosomes6. small vesicle with digestive enzymes Centrioles7. organelles needed to form cilia and flagella Chromatin8. thread-like strand of DNA with associated proteins Rough ER9. site of secretory and membrane protein synthesis Golgi Complex10. site where protein products are stored, packaged, and exported Nucleus11. contains DNA that control cellular activities Nucleolus12. site of ribosome synthesis Cytoskeleton13. gives the cell shape, support, movement, and holds organelles in position Plasma Membrane14. controls movement of substances into or out of the cell Microvilli 15. folds of the plasma membrane that increase the cell's surface area Peroxisomes 16. detoxifies harmful substances, produces hydrogen peroxide, and oxidizes amino acids Nuclear Membrane17. double membrane that separates the nucleus from the cytoplasm Secretory Vesicles18. a small membranous sac that delivers proteins to the plasma membrane to exit the cell B. Phases of the Cell Cycle Write the phase of the cell cycle that the phrase describes.
Cytokinesis1. cytoplasmic division Interphase2. cell performing normal functions; longest phase Mitosis3. nuclear division Metaphase4. chromatid pairs line up at equatorial plate Prophase5. chromatin condenses into chromosomes Telophase6. spindle fibers break up; nucleus reappears Anaphase7. centromeres divide; chromosomes move to opposite poles Prophase8. nuclear membrane disassembles and disappears Telophase
