3) The advantage of light microscopy over electron microscopy is that A) light microscopy provides for higher magnification than electron microscopy. B) light microscopy provides for higher resolving power than electron microscopy. *C) light microscopy allows one to view dynamic processes in living cells. D) both A and B E) both B and C 8) Which of the following are prokaryotic cells? A) plants B) fungi *C) bacteria D) animals E) B and C only 9) All of the following are part of a prokaryotic cell except A) DNA. B) a cell wall. C) a plasma membrane. D) ribosomes. *E) edonplasmic reticulum 10) The volume enclosed by the plasma membrane of plant cells is often much larger than the corresponding volume in animal cells. The most reasonable explanation for this observation is that A) plant cells are capable of having a much higher surface-to-volume ratio than animal cells. B) plant cells have a much more highly convoluted (folded) plasma membrane than animal cells. *C) plant cells contain a large vacuole that reduces the volume of the cytoplasm. D) animal cells are more spherical, while plant cells are elongated. E) the basic functions of plant cells are very different from those of animal cells. For the following questions, use the lettered answers to match the structure to its proper cell type. Choose the most inclusive category. Each answer may be used once, more than once, or not at all. A. a feature of all cells B. found in prokaryotic cells only C. found in eukaryotic cells only D. found in plant cells only E. found in animal cells only 12) plasma membrane 13) tonoplast 14) nucleoid 16) Large numbers of ribosomes are present in cells that specialize in producing which of the following molecules? A) lipids B) starches *C) proteins D) steroids E) glucose 18) Which of the following organelles is not a common destination for small vesicles that bud off the Golgi apparatus? A) plasma membrane B) lysosomes 1

C) vacuole *D) endoplasmic reticulum E) all of the above 21) Which type of organelle is primarily involved in the synthesis of oils, phospholipids, and steroids? A) ribosome B) lysosome *C) smooth endoplasmic reticulum D) mitochondrion E) contractile vacuole 22) Which structure is the site of the synthesis of proteins that may be exported from the cell? *A) rough ER B) lysosomes C) plasmodesmata D) Golgi vesicles E) tight junctions 24) The Golgi apparatus has a polarity or sidedness to its structure and function. Which of the following statements correctly describes this polarity? A) Transport vesicles fuse with one side of the Golgi and leave from the opposite side. B) Proteins in the membrane of the Golgi may be sorted and modified as they move from one side of the Golgi to the other. C) Lipids in the membrane of the Golgi may be sorted and modified as they move from one side of the
