CHAPTER 6: CELLS & ORGANELLES WORKSHEET GENERAL INSTRUCTIONS: 1. Type your answers into ANSWER column and upload your worksheet as a docx or pdf file ONLY! 2. DO NOT change the formatting or add carriage returns (hitting the key) SECTION 1: MULIPLE CHOICE: Pick the BEST answer from the choices given and place the LETTER of your choice in the ANSWER column QUESTION ANSWER C C E D E B C 1. The cell junctions in plant cells that provide channels between adjacent cells are generally _____. A. synapses B. communicating junctions C. plasmodesmata D. anchoring junctions E. tight junctions 2. An organelle which plant cells have but animal cells do not is ____________. A. chloroplasts B. ribosomes C. nucleus D. mitochondria E. none of these 3. Which one of these organelles, if any, are NOT bound by a membrane? A. nucleus B. chloroplasts C. mitochondria D. lysosomes E. ribosomes 4. In addition to a plasma membrane, plant cells have additional protection in the form of _________-, which animal cells do not. A. mitochondria B. endoplasmic reticulum C. mega-membranes D. cell walls E. micromembranes 5. Which of the following is NOT true of prokaryotic cells? A. Are smaller than eukaryotic cells B. Lack internal structures surrounded by membranes C. Lack a nucleus D. Have a nucleus E. Only A and C are true 6. Smooth endoplasmic reticulum is involved in the production of _____. A. produces lipids, including steroids B. proteins C. ATP D. there is no such thing as “smooth” ER E. none of these 7. Why is “rough” endoplasmic reticulum (ER) described as rough? A. the membranes are studded with ribosomes which make proteins B. the membranes are more folded than in “smooth “ ER C. the rough ER makes granular substances like sugars and carbohydrates, hence the “rough” appearance D. there is no such thing as “rough” ER E. none of the above SECTION 2: Name the 3 domains of life and list what kind of cell they are based 8. EUKARYOTIC 9. PROKARYOTIC What are the two kinds of cell? Name: 10. Domain 1? BACTERIA Name: 11. Domain 2? ARCHAEA Name: 12. Domain 3? Eukarya Cell Type: PTOKARYOTE Cell Type: PROKARYOTE Cell Type: eukaryote SECTION 3: Match the Organelle to Its Function or Description Place your answer (LETTER ONLY) in the ANSWER column ANSWER Organelle Function or Description 13. Lysosomes E A. Lipid bilayer in which a variety of proteins are distributed (the “fluid mosaic model”) 14. Cilia or flagella J B. Involved in modifying, “shipping” and packaging for transport of materials produced by other organelles 15. Mitochondria F C. Manufacture of proteins 16. Cell membrane A D. Network of internal membranes connected to the nucleus and extending throughout the cell. There are two different kinds “rough” and “smooth”. 17. Ribosomes C E. Contain digestive enzymes which breakdown food items and worn-out cell parts 18. Nucleus H F. Responsible for cellular respiration (“powerhouses” of the cell) G. Organelles that contain chlorophyll and used by plants for photosynthesis 19. Chloroplasts G H. “Control center” of the cell and contains the cell’s chromosomes 20. Endoplasmic Reticulum D I. Organelles responsible for the assembly of ribosomes I 21. Nucleolus J. External hollow tubes made of microtubules that are used by cells to move about (mobile appendages) B 22. Golgi apparatus Section 4: Put a check or an “X” in the appropriate column(s) to indicate whether the following organelles are found in plant cells, animal cells or both. Organelle Cell wall Centrioles Chloroplast Cytoskeleton Endoplasmic reticulum 28. Golgi apparatus 23. 24. 25. 26. 27. Plant ✔ Animal X X ✔ ✔ ✔ ✔ ✔ ✔ ✔ ✔ X 29. 30. 31. 32. 33.
