Chapter 5 Cell Structure and Function
1) All of the following are true of the plasma membrane, except
A) it is mainly composed of a phospholipid bilayer.
B) it is selectively permeable to various substances, controlling which substances can cross the membrane.
C) the glycocalyx provides structural integrity to the plasma membrane.
D) transmembrane proteins may function as ion channels, enzymes, or receptors.
E) charged or large molecules can sometimes enter a cell via membrane proteins.
2) What is the difference in function between the smooth and rough endoplasmic reticulum (ER)?
A) The rough ER produces ATP, while the smooth ER does not.
B) The rough ER helps with cellular movements, while the smooth ER does not.
C) The rough ER conducts lipid synthesis, while the smooth ER conducts protein synthesis.
D) The rough ER breaks down lipids, while the smooth ER breaks down proteins and debris.
E) The rough ER conducts protein synthesis, while the smooth ER conducts lipid synthesis.
3) The cytosol and cytoplasmic organelles are components of the ________.
A) cytoskeleton
B) cytoplasm
C) mitochondria
D) nucleus
E) plasma membrane
4) The nucleolus is the site of DNA replication.
5) Which of the following organelles are sometimes called "suicide sacs," because they are able to destroy the whole cell?
A) Ribosomes
B) Golgi apparatus
C) Lysosomes
D) Mitochondria
E) Centrioles
6) All of the following structures are found in (or surrounding) the nucleus of a cell, except the ________.
A) centrioles
B) chromatin
C) nucleolus
D) nuclear envelope
E) nuclear pores
7) Which of the following organelles is sometimes called the powerhouse of the cell, because of its role in ATP production?
A) Golgi apparatus
B) Centrosome
C) Lysosomes
D) Mitochondria
E) Peroxisomes
8) The nuclear envelope is a double-layered membrane, like the plasma membrane.
9) All of the following structures are involved in motility, except
A) microvilli.
B) cilia.
C) microtubules.
D) microfilaments.
E) flagella.
10) What do lysosomes and peroxisomes have in common?
A) They both have specific roles in cell division
B) They are both involved in ATP production for the cell.
C) They are both vesicles (sacs) of enzymes.
D) They both produce proteins for the cell.
E) They are both part of the cytoskeleton.
11) The rough endoplasmic reticulum is a group of flattened sacs that packages glycoproteins to be transported around the cell or excreted.
12) All of the following are true of the centrioles, except
A) they are located within the centrosome.
B) they are part of the cytoskeleton.
C) they consist of microtubules.
D) they organize the mitotic spindle during cell division.
E) they are nonmembranous organelles.
13) All of the organelles in the cell are membrane-bound.
14) The plasma membrane of a cell can also be called the cell membrane.
15) Which of the following organelles provide additional surface area for absorption?
A) Cilia
B) Microvilli
C) Ribosomes
D) Flagella
E) Centrioles
16) The best way to observe cheek cells is under a dissecting microscope; they are too large to view under a compound light microscope.
