Name:__________________________________ Self-Assessment – Cell Parts 1. Cells are the basic units of STRUCTURE & FUNCTION in living things. 2. What two organelles do plant cells have that animal cells do not? CELL WALL & CHLOROPLASTS 3. What organelles do animal cells have that plant cells do not? CENTRIOLES & CILIA Match the cell structure on the left with the definition below.. 4. ___c__ cell membrane a. portion of the cell between the cell membrane and the nucleus 5. ___a__ cytoplasm b. modifies, sorts, and packages materials from the endoplasmic reticulum 6. __e___ nucleus c. protects the cells and regulates what materials enter and leave the cells 7. __j___ER d. contains the green pigment chlorophyll 8. __b___ Golgi apparatus e. contains nearly all of the cells DNA 9. f. sac-like structure often used to store materials such as water, salts & proteins __h__ ribosome 10. __i__ mitochondria g. made mostly of cellulose 11. __d__ chloroplast h. produces proteins by following coded instructions from the nucleus 12. __f__ vacuole i. converts chemical energy stored in food into compounds more usable by cells 13. __g___ cell wall j. two types; numerous functions including protein transport & lipid synthesis Respond to the following questions in complete sentences; be sure to support your answers: 14. In a recent murder mystery, a woman died in minutes after consuming cyanide-laced sugar. Forensic scientists did research and found out that the death was caused by the lack of the energy rich molecule ATP. Which cellular organelle was affected by this poison? Explain your answer. MITOCHONDRIA - ATP IS CELLULAR ENERGY WHICH IS PRODUCED DURING CELLULAR RESPIRATION IN THE MITOCHONDRIA 15. In a classroom experiment, you ground up some spinach in distilled water and filtered the liquid onto a piece of filter paper. The isolated organelles absorbed carbon dioxide and released oxygen. Which cellular organelle was most likely on the filter paper? Explain your answer. CHLOROPLASTS - ABSORB CARBON DIOXIDE AND RELEASE OXYGEN DURING PHOTOSYNTHESIS 16. Would you expect the same results as described in question 4 above if you ground up mushroom cells instead of spinach cells? Explain your answer. NO – MUSHROOMS ARE FUNGI AND ARE NOT PHOTOSYNTHETIC 17. Examination of a sample of glandular cells from an unknown body location reveals an extensive network of endoplasmic reticulum. Select all substances from the list below that may be produced by these cells. Explain your answers. a. Skin oils b. Digestive enzymes c. Sex hormones d. cholesterol e. ear wax f. cellulose THE ATTACHED RIBOSOMES OF ROUGH ER PRODUCE PROTEIN (ENZYMES) & SMOOTH ER SYNTHESIZES LIPIDS (OILS, HORMONES, CHOLESTEROL & WAX) 18. A person who smokes destroys the cilia on the columnar epithelial cells that line the trachea. In most cases, the cilia will regenerate. If the cilia did not regenerate or did not resume proper function, which cellular organelle might be implicated in the problem? Explain your answer CENTRIOLES OR CYTOSKELETON - CENTRIOLES GIVE RISE TO CYTOSKELETON AND CILIA ARE DERIVED FROM THE CYTOSKELETON Labeling: Identify the structures of the organelles indicated below on the lines provided 1. LYSOSOME (FILLED WITH PARTICLES) 2. ROUGH ER 3. DNA (CHROMOSOMES) 4. GOLGI APPARATUS 5. VACUOLE 6. MITOCHONDRIA 7. ATTACHED RIBOSOMES (DOTS) 8. NUCLEOLUS 9. NUCLEAR ENVELOPE 10. CENTRIOLES (2 RODS) 11. PLASMA MEMBRANE 12. CYTOPLASM
