Cell Organelles Worksheet
Situation: We have previously learned about 10 cell organelles found in plant and/or animal
cells. Although we have described a general eukaryotic cell, the number of each type of
organelle varies from cell to cell. For example, a muscle cell contains many more mitochondria
than a stomach cell since muscle cells require a lot of energy to do their job. Bone cells on the
other hand may have extra ribosomes to continue making the proteins necessary to grow your
bones.
Task: Read about each of the four cells below. Then write one paragraph for each organelle
describing the 2 most important organelles for that cell. These are the organelles we would
likely find in the highest quantities when observing the cells using an electron microscope.
Intestine Cell
Intestine cells in the digestive system are used to absorb nutrients from your digested food.
They need organelles that help determine what enters (nutrients) and exits (waste) the
intestine cells. In order to export wastes that are captured in your intestines, these cells need
organelles that can package and ship materials out of the cell. Which two organelles would a
scientist find in the greatest quantity when observing intestine cells? Support your answer
with evidence from the description.

Nerve Cell
Nerve cells are responsible for transmitting signals from your brain to all parts of your body.
They accomplish this task by exporting salts (ex. Sodium, potassium, calcium) from inside of one
cell to an adjacent cell. They have many organelles that assist with exporting the salts. These
positively and negatively charged ions create the electrical signals that you know as pain,
feeling, sensation, etc. In order to have energy to continue exporting salts from the cell,
another organelle is needed to help release energy. Which two organelles would a scientist
find in the greatest quantity when observing nerve cells? Support your answer with evidence
from the description.

Heart Cell
Heart cells are one of the hardest working cells in your body. These specialized muscle cells
cannot stop beating your entire life, so it is crucial that they receive a constant supply of
energy. In order to repair the heart as it uses energy to beat, another group of organelles are
needed that create the proteins needed to build things in a cell. . Which two organelles would
a scientist find in the greatest quantity when observing heart cells? Support your answer
with evidence from the description.

Skin Cell
Skin cells produce a protein called keratin that is found in skin, hair, and nails. In order to
produce this protein that makes skin a strong protective covering, many small protein
generating organelles are needed. To transport these proteins from one end of the cell to
another end, another type of organelle is needed in great quantities that appear as a network
of tube like canals. Which two organelles would a scientist find in the greatest quantity when
observing heart cells? Support your answer with evidence from the description.

Cell Organelles Worksheet
Directions: Label the cells using the following questions as clues.
1. Rigid outer cover found outside of the cell membrane and only found in plant cells
2. The covering that surrounds the cell, holds it together, and determines what can enter/exit the cell
3. Large, round, water-filled sac used as a storage area of the cell
4. Controls the cell’s activities (brain) and contains DNA (genetic information)
5. Large, green, oval shaped organelles in which photosynthesis takes place
6. Organelles that release energy (powerhouse of the cell)
7. Clear, thick, gel-like fluid between the cell membrane and the nucleus
8. Tube like canals that run through the cytoplasm and carry protein and other materials from one part
of the cell to another
9. The organelles that make protein
10. Stores and packages materials for export from the cell
