a. A green pigment found in the chloroplasts of plants, algae, and some bacteria responsible for
trapping light energy from the sun.
b. A cell structure that contains DNA, the chemical instructions that direct all of the cell’s
activities.
c. A structure in the cells of plants and some other organisms that captures energy from sunlight
and uses it to produce food.
d. A cell structure that forms a maze of passageways in which materials (ex: some lipids and
proteins) are produced and carried to the Golgi apparatus and other cell parts.
e. A structure in a cell that receives proteins and other newly formed materials from the ER,
modifies them, packages them, and distributes them to other parts of the cell.
f. A small, round cell structure containing chemicals that break down materials in the cell into
smaller pieces. (ex: large food particles)
g. A rod-shaped cell structure that converts chemical energy in food to energy the cell can use to
carry out its functions.
h. The boundary around the nucleus that keeps the DNA inside and organelles outside the
nucleus.
i.
A small grain-like structure in the cytoplasm of a cell where proteins are made.
j.
A sac inside a cell that acts as a storage area.

SECTION 4:
Directions: Complete each sentence with the appropriate vocabulary word.
1. If the _______________________________________ in a cell were to stop functioning then the cell would die
because it would have no proteins.
2. Prokaryotic cells are different from eukaryotic cells because they do not have a
_________________________________________.
3. The _____________________________________________ is like FedEx because it packages materials, and ships
them throughout the cell.
4. The reason that plant cells are green is because they have a substance called
______________________________________ in them that traps sunlight for photosynthesis.
5. ____________________________________ are like packing boxes because they are used in the cell to store
things.
6. The function of _____________________________________ can be compared to that of the stomach because it
digests large food particles into smaller parts.
7. The ______________________________________________ is a very important structure in the cell because it is
responsible for keeping the DNA inside the nucleus.
8. Animal cells are unable to make their own food because they do not have
_______________________________________ like plant cells do.
9. There are two types of __________________________________________________ rough (with ribosomes) and
smooth (without ribosomes).
10. ___________________________________________ are known as the power houses of the cell because they give
the cell energy necessary to function.
