BIOL 2261 Chapter 4: Functional Anatomy of Prokaryotic
and Eukaryotic Cells Questions With Complete Solutions
"Run" movement Correct Answer Random walk; counter-
clockwise
"Tumble" movement Correct Answer Random changes in
direction, clockwise
Acid-fast bacteria Correct Answer Peptidoglycan + mycolic
acid (similar to gram-positive)
Active processes Correct Answer When substances move
from areas of low to high concentration (energy expended)
Active transport Correct Answer The cell requires energy in
the form of ATP
Aquaporins Correct Answer Integral membrane proteins
(water channels)
Archaea cell wall Correct Answer No walls or walls with
pseudomurein
Archaella (archaellum) Correct Answer Archaeal motility
structure
Axial filaments/endoflagella Correct Answer Bundles of
fibrils that arise at the ends of the cell beneath an outer sheath
and spiral around the cell
, Bacterial chromosome Correct Answer Circular thread of
DNA that contains the cell's genetic information
Capsule Correct Answer When the glycocalyx is organized
and firmly attached to the cell wall
Cell wall locations Correct Answer Found in plants, algae,
and fungi
Centrosomes Correct Answer Networks of protein fibers and
centrioles; form the mitotic spindle; critical role in cell division
Chloroplasts Correct Answer Locations for photosynthesis
(algae and green plants)
Chromatin Correct Answer Thread-like mass composed of
histones
Chromatophores Correct Answer Photosynthetic pigments
and enzymes in foldings of membrane
Chromosomes Correct Answer Short & thick rod-like bodies
of chromatin condensed during nuclear division
Cilia (cilum) Correct Answer Short & frequent projections
from cell
Conjugation (sex) pil Correct Answer DNA transfer from one
bacterium cell to another
Cristae Correct Answer Inner folds of mitochondria
