1 期中考模擬試題 -2 Chapter 6 A Tour of the Cell Multiple - Choice Questions 1) All of the following are part of a prokaryotic cell except A) DNA. B) a cell wall. C) a plasma membrane. D) ribosomes. E) an endoplasmic reticulum. Answer: Topic: Concept 6.2 Skill: Knowledge/Comprehension 2) 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. Answer: Topic: Concept 6.2 Skill: Synthesis/Evaluation 3) Which of the following is a major cause of the size limits for certain types of cells? A) the evolution of larger cells after the evolution of smaller cells B) the difference in plasma membranes between prokaryotes and eukaryotes C) the evolution of eukaryotes after the evolution of prokaryotes D) the need for a surface area of sufficient area to allow the cell's function E) the observation that longer cells usually have greater cell volume Answer: Topic: Concept 6.2 Skill: Knowledge/Comprehension 4) 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 Answer: Topic: Concept 6.3 Skill: Knowledge/Comprehension

2 5) The nuclear lamina is an array of filaments on the inner side of the nuclear membrane. If a method were found that could cause the lamina to fall into disarray, what would you expect to be the most likely consequence? A) the loss of all nuclear function B) the inability of the cell to withstand enzymatic digestion C) a change in the shape of the nucleus D) failure of chromosomes to carry genetic information E) inability of the nucleus to keep out destructive chemicals Answer: Topic: Concept 6.3 Skill: Synthesis/Evaluation 6) Under which of the following conditions would you expect to find a cell with a predominance of free ribosomes? A) a cell that is secreting proteins B) a cell that is producing cytoplasmic enzymes C) a cell that is constructing its cell wall or extracellular matrix D) a cell that is digesting food particles E) a cell that is enlarging its vacuole Answer: Topic: Concepts 6.3, 6.4 Skill: Application/Analysis 7) Which type of organelle is primarily involved in the synthesis of oils, phospholipids, and steroids? A)
