Cell Structure and Function Practice
1.
The National Aeronautics and Space Agency (NASA) has a command center in
Houston, Texas, that directs space missions. Which part of a cell functions like this
command center?
A. Plasma membrane
B. Mitochondria
C. Nucleus
D. Vacuole
2.

organelles provided energy and had a green color. The organelles were most likely:
A. vacuoles
B. chloroplasts
C. mitochondria
D. nuclei
3.
Your observing a rather large cell under the microscope. It is clearly visible and
has a dark area within it which is identified as a nucleus. There is also a dark
border around the cell membrane which you correctly identify as a cell wall. This cell
may belong to a _______________ and is ________________.
A. plant, eukaryotic
B. plant, prokaryotic
C. animal, prokaryotic
D. animal, eukaryotic
4.
Which of these is a function of the cell membrane in all cells?
A Producing cellular nutrients
B Preserving cellular wastes
C Neutralizing chemicals
D Maintaining homeostasis
5.
Which of the following pairs of terms are not related?
A. nucleus – DNA
B. flagella – cilia
C. chloroplasts – chlorophyll
D. nucleus – cell wall
The cell membrane regulates what enters and leaves the cell and also provides protection
and support. The core of nearly all cell membranes is a double-layered sheet called a lipid
bi-layer. Most materials entering the cell pass across this membrane by diffusion. The
graph shows the sizes of several molecules that can diffuse across a lipid bi-layer.
6.
Which three materials according to their size would diffuse most quickly across the
lipid bi-layer.
A. urea , water , glucose
B. ethanol , urea , glucose
C. oxygen , water , urea
D. water , ethanol , oxygen
7.
You prepare a wet mount of some cellular tissue. Look at the slide below and
determine what type of cells you are observing.
A.
B.
C.
D.
muscle cell with mitochondria
nerve cells with nuclei
plant cells with chloroplast
bacteria cells with DNA strand
8.
Plasma membranes are selectively permeable. This means that
A. anything can pass into or out of a cell.
B. they regulate the passage of material into and out of the cell.
C. glucose cannot enter the cell.
D. cholesterol cannot enter the cell
9.
Identify the organelle pictured.
A. chloroplast
B. mitochondrium
C. lysosome
D. ribosome
10.
What part of the cell serves as the intracellular highway?
A. mitochondrion
B. chloroplast
C. endoplasmic reticulum
D. ribosome
11.
Which is not part of the cell theory:
A. cells vary in size but have the same shape,
B. all organisms are made of one or more cells,
C. all cells carry on their own life activities,
D. new cells arise only from other living cells
12.
What organelle contains digestive enzymes to destroy unwanted or unneeded items
in the cell?
A. vacuole
B. Golgi
C. ribosome
D. lysosome
