Chapter 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: E
Topic: Concept 6.2
Skill: Knowledge

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: C

3) Which of the following comparisons between prokaryotic and eukaryotic cells is incorrect? A) The lack of organelles in prokaryotes means that they are structurally less complex than eukaryotes. B) The lack of internal membranes means that prokaryotes cannot compartmentalize function to the same extent as eukaryotes. C) All membrane function in prokaryotes is accomplished in the plasma membrane, while in eukaryotes, these functions are more distributed among the organelles. D) The specialization of function in organelles suggests that eukaryotes will contain a wider variety of phospholipids than prokaryotes. E) The lack of organelles in prokaryotes means that the basic cellular functions are different in prokaryotes than in eukaryotes. Answer: E
