by Huether, McCance Test Bank
,
,Chapter 1. Cellular Biology
MULTIPLE CHOICE
1. A student is observing a cell under the microscope. It is observed to have supercoiled DNA
with histones. Which of the following would also be observed by the student?
a. A single circular chromosome
b. A nucleus
c. Free-floating nuclear material
d. No organelles
ANS: B
The cell described is a eukaryotic cell, so it has histones and a supercoiled DNA within its
nucleus; thus, the nucleus should be observed.
A single circular chromosome is characteristic of prokaryotic cells, which do not have histones.
Free-floating nuclear material describes a prokaryotic cell, which would not have a distinct
nucleus.
Eukaryotic cells have membrane bounded cellular components called organelles. No
organellesdescribes a prokaryotic cell.
, 2. A nurse is instructing the staff about cellular functions. Which cellular function is the
nursedescribing when an isolated cell absorbs oxygen and uses it to transform nutrients to
energy?
a. Metabolic absorption
b. Communication
c. Secretion
d. Respiration
