Which of the following is NOT a membranous organelle?
r r r r r r r r
a. Lysosomes
r
b. Peroxisomes
r
c. Mitochondria
r
d. Ribosomes
r
e. Endoplasmic reticulum
r r
Answer: d r
Lysosomes, peroxisomes, mitochondria, and endoplasmic reticulum are all memb
r r r r r r r r
ranous organelles. r
2.
Which organelle contains digestive enzymes?
r r r r
a. Rough endoplasmic reticulum
r r r
b. Smooth endoplasmic reticulum
r r r
c. Lysosome
r
d. Golgi apparatus
r r
e. Mitochondria
r
Answer: c r
Endoplasmic reticulum is a system of tubules. If there are ribosomes on the tubules
r r r r r r r r r r r r r
, it is termed "rough endoplasmic reticulum". Ribosomes produce proteins. When t
r r r r r r r r r r r
he ribosomes are attached to endoplasmic reticulum, the proteins produced by the
r r r r r r r r r r r r
ribosomes are exported. If there are no ribosomes on the endoplasmic reticulum, it
r r r r r r r r r r r r r
is called "smooth endoplasmic reticulum". The role of smooth endoplasmic reticul
r r r r r r r r r r
um is lipid metabolism.
r r r
Lysosomes are membrane bound sacs of digestive enzymes. They are nicknamed "
r r r r r r r r r r r

suicide sacs". r
The Golgi apparatus are stacks of membranous sacs. Proteins are sorted and packa
r r r r r r r r r r r r
ged in the Golgi apparatus.
r r r r
The mitochondria is the site of ATP production for the cell. ATP is the energy curr
r r r r r r r r r r r r r r r
ency of the cell. Mitochondria are nicknamed, the "powerhouse".

e. Nucleoli
r
Answer: d r
The ribosomes are the site of protein synthesis.
r r r r r r r
Peroxisomes contain enzymes for detoxification. One of the enzymes within pero
r r r r r r r r r r
xisomes is catalase. Catalase is involved in the breakdown of hydrogen peroxide.
r r r r r r r r r r r
Microfilaments are made of actin. They form the cells cytoskeleton. r r r r r r r r r
Centrioles are composed of microtubules. Centrioles are at the base of cilia and fla
r r r r r r r r r r r r r
gella. They are also involved with cell division.
r r r r r r r
Ribosomes are assembled in the nucleoli. The nucleolus is a spherical area within t
r r r r r r r r r r r r r
he cell nucleus.

Which of the following is NOT considered an inclusion?
r r r r r r r r
a. Pigment
r
b. Glycogen
r
c. Lipid
r
d. Secretory granules
r r
e. Mitochondria
r
Answer: e r
Mitochondria is an organelle. Pigment, glycogen, lipid, and secretory granules are
r r r r r r r r r r r
all considered inclusions. Organelles perform an activity; they have a job; they req
r r r r r r r r r r r r
uire energy. Inclusions are for storage. Inclusions do not perform an energy requiri
r r r r r r r r r r r r
ng job. r

lectively, the cytoplasm and nucleus form the protoplasm of a cell. The folds on th
r r r r r r r r r r r r r r
e inner mitochodrial membrane are called cristae. The cytoplasm that surrounds or
r r r r r r r r r r r
ganelles is the cytoplasmic ground substance or cytosol.

Answer: b r
Endotyosis is the term for the process cells use to have substances enter them. Exo
r r r r r r r r r r r r r r
ctyosis is the term for the process cells use to remove substances. Phagocytosis is "
r r r r r r r r r r r r r r
cell eating" and is used for the transport of particulate matter. Pinocytosis is "cell d
r r r r r r r r r r r r r r
rinking". Active transport is a method which requires energy.
