1.
Which of the following is NOT a membranous organelle?
a. Lysosomes
b. Peroxisomes
c. Mitochondria
d. Ribosomes
e. Endoplasmic reticulum
Answer: d
Lysosomes, peroxisomes, mitochondria, and endoplasmic reticulum are all membranous organelles.
2.
Which organelle contains digestive enzymes?
a. Rough endoplasmic reticulum
b. Smooth endoplasmic reticulum
c. Lysosome
d. Golgi apparatus
e. Mitochondria
Answer: c
Endoplasmic reticulum is a system of tubules. If there are ribosomes on the tubules, it is termed "rough endoplas
mic reticulum". Ribosomes produce proteins. When the ribosomes are attached to endoplasmic reticulum, the pr
oteins produced by the ribosomes are exported. If there are no ribosomes on the endoplasmic reticulum, it is call
ed "smooth endoplasmic reticulum". The role of smooth endoplasmic reticulum is lipid metabolism.
Lysosomes are membrane bound sacs of digestive enzymes. They are nicknamed "suicide sacs".
The Golgi apparatus are stacks of membranous sacs. Proteins are sorted and packaged in the Golgi apparatus.
The mitochondria is the site of ATP production for the cell. ATP is the energy currency of the cell. Mitochondri
a are nicknamed, the "powerhouse".

Which organelle is considered the powerhouse of the cell?
a. Rough endoplasmic reticulum
b. Smooth endoplasmic reticulum

What structure is at the base of cilia?
a. Ribosomes
b. Peroxisome
c. Microfilaments
d. Centrioles
e. Nucleoli
Answer: d
The ribosomes are the site of protein synthesis.
Peroxisomes contain enzymes for detoxification. One of the enzymes within peroxisomes is catalase. Catalase is
involved in the breakdown of hydrogen peroxide.
Microfilaments are made of actin. They form the cells cytoskeleton.
Centrioles are composed of microtubules. Centrioles are at the base of cilia and flagella. They are also involved
with cell division.
Ribosomes are assembled in the nucleoli. The nucleolus is a spherical area within the cell nucleus.
5.
Which of the following is NOT considered an inclusion?
a. Pigment
b. Glycogen
c. Lipid
d. Secretory granules
e. Mitochondria
Answer: e
Mitochondria is an organelle. Pigment, glycogen, lipid, and secretory granules are all considered inclusions. Org
anelles perform an activity; they have a job; they require energy. Inclusions are for storage. Inclusions do not pe
rform an energy requiring job.
6.
Collectively, what is the cytoplasm and nucleus called?
a. Plasmalemma
b. Glycocalyx
c. Protoplasm
d. Cristae
e. Ground substance
Answer: c
The cell boundary is defined by the cell membrane or plasmalemma. Glycocalyx is a polysacchride that can be f
ound on the outer surface of the cell membranes. Collectively, the cytoplasm and nucleus form the protoplasm o
f a cell. The folds on the inner mitochodrial membrane are called cristae. The cytoplasm that surrounds organell
es is the cytoplasmic ground substance or cytosol.
7.
How thick is the plasma membrane?
a. 8-10 angstroms
b. 8-10 nanometers
c. 8-10 micrometers
d. 8-10 millimeters
e. None of the above
Answer: b
The plasma membrane is 8-10 nanometers thick.

What is the term for the general process that cells us to expunge material from the cell?
a. Endocytosis
b. Exocytosis
c. Pinocytosis
d. Phagocytosis
e. Active transport
Answer: b
Endotyosis is the term for the process cells use to have substances enter them. Exoctyosis is the term for the pro
cess cells use to remove substances. Phagocytosis is "cell eating" and is used for the transport of particulate matt
er. Pinocytosis is "cell drinking". Active transport is a method which requires energy.

a. Rough endoplasmic reticulum
