1) Cyanide is a poison that prevents mitochondria from using oxygen. As a result, the mitochondria cannot
produce
A.
B.
C.
D.
lipids
sugar
minerals
energy
2) Use the information and the figure below to answer the following.
The diagram below shows a colony of prokaryotes and a single-celled eukaryote. The eukaryote contains
organelles that resemble the three types of bacteria found in the colony of prokaryotes. More than a billion years
ago, bacteria like these may have joined other prokaryotes to form colonies of cells. Researchers think that these
once free-living prokaryotes became the organelles of modern-day eukaryotes.
In the eukaryote, which of these organelles are used to make sugars?
A.
B.
C.
D.
flagella
ribosomes
mitochondria
chloroplasts
3. A group of students studied the effect of light intensity on the rate of
a cell process in Elodea plants. The students exposed Elodea plants to
different light intensities. A gas was produced by the cell process. The
amount of this gas was measured. The rate of the cell process was
determined by the amount of gas produced. A graph of the students'
measurements is shown below.
Which of these parts of the Elodea plant cell produces the gas measured in the experiment?
A.
B.
C.
D.
mitochondrion
chloroplast
ribosome
nucleus
Use the information and the diagrams below to answer the following.
A student observed different types of cells under a microscope. Four of the cells he observed are shown below.
4. Cell 2 and 3 both have an organized structure that contains all of the genetic information and directions for
the cell. This organelle is known as the
A.
B.
C.
D.
cilia
flagella
vacuoles
nucleus
5. Which of these structures in Cell 3 releases energy for use in cell processes?
A.
B.
C.
D.
nucleus
cell wall
chloroplast
mitochondrion
ESSAY:
All organisms must be able to exchange chemical substances between their cells and their environment. Some
organisms are unicellular and others are multicellular. These organisms have different strategies to obtain and
use these chemical substances.

What chemical substances must be exchanged between each organism and its environment?
Describe the processes that cause these chemical substances to move into and out of cells.
Describe the role of the cell membrane in the exchange of materials in both types of organism.
Describe the role of body systems in the exchange of materials in a multicellular organism.
