1. Cytoplasm in a cell is:
a. the portion between the cell wall and the nucleus
b. the portion between the plasma membrane and the cell wall
c. the portion between the plasma membrane and the nucleus
d. the portion inside the nucleus
2. Which of the following parts of a cell are easily seen through a microscope:
a. Cell wall, nucleus and mitochondria
b. Cell membrane, nucleus and cytoplasm
c. All of the organelles are seen easily
d. I have no clue
3. The clear liquid that the organelles are suspended in is called:
a. Lysol
b. Cytosol
c. Pine Sol
d. Plasma
4. “ER” is the initials for which of the following organelles.
a. Ectoplasmic Respeculum
b. Endoplasmic Curriculum
c. Electronic Reticulum
d. Endoplasmic Reticulum
5. “ER” that is known as “Rough ER” is so named because it contains:
a. mitochondria
b. gravel
c. ribosomes
d. RNA
6. Mitochondria are able to divide themselves. They also contain inner folds called:
a. Crystals
b. Cristae
c. Villi
d. Ganglia
7. Which of the following is a active mechanism:
a. Endocytosis
b. Facilitated diffusion
c. Osmosis
d. Diffusion
8. In facilitated diffusion, molecules and ions spread:
a. Up the concentration gradient (from low to high)
b. Down the concentration gradient (from high to low)
c. What’s a concentration gradient?
d. At a very slow rate
9. Facilitated diffusion is most like:
a. Getting into a concert with the proper ticket
b. Doing push-ups
c. Running a long distance, then taking a drink of water
d. Sleeping
10. Osmosis is like diffusion, except:
a. Is travels up the concentration gradient
b. It deals with water
c. It’s a type of active transport
d. It’s not like diffusion at all
11. Any solution that has the same osmotic pressure as the body fluid that surrounds:
a. Is isotonic
b. Is isometric
c. Is hypertonic
d. Is hypotonic
12. Active transport is different from facilitated diffusion because:
a. Facilitated diffusion travels down the concentration gradient
b. Active transport travels down the concentration gradient
c. Active transport deals with water only
d. They are actually the same
e. Both “a” and “c”
13. Exocytosis is a process in which molecules:
a. Leave the cell by vesicles
b. Enter the cell through vesicles
c. Are broken down
d. Are regenerated
14. Endocytosis and exocytosis both:
a. Use cellular energy
b. Occur in the nucleus
c. Are passive mechanisms
d. None of the above
A. A cell organelle that helps make and package materials to be transported out of the
cell.
B. A cell organelle where protein synthesis occurs.
C. A collection of genetically identical cells that are permanently associated but in
which little or no integration of cell activities occurs.
D. A collection of tissues that carry out a specialized function of the body.
E. A fluid-filled vesicle found in the cytoplasm of plant cells or protists.
F. A group of organs that work together to perform a body function.
G. A group of similar cells that perform a common function.
H. A long, hair-like structure that grows out of a cell and enables the cell to move.
I. A phospholipid layer that covers a cell’s surface and acts as a barrier between the
inside of a cell and the cell’s environment.
J. A single-celled organism that does not have a nucleus or membrane-bound
organelles.
K. A small cavity or sac that contains materials in a eukaryotic cell.
L. A system of membranes that is found in a cell’s cytoplasm and that assists in the
production, processing, and transport of proteins and in the production of lipids.
M. An organelle found in plant and algae cells where photosynthesis occurs.
N. An organism made up of cells that have a nucleus and membrane-bound
organelles.
O. In a eukaryotic cell, a membrane-bound organelle that contains the cell’s DNA.
P. In eukaryotic cells, the cell organelle that is surrounded by two membranes and that
is the site of cellular respiration.
Q. One of the small bodies that are found in the cytoplasm of a cell and that are
specialized to perform a specific function.
R. The region of the cell within the membrane.
