Notes
There are a variety of different animal cells, all with unique functions. Within the human body alone there are is a wide variety of cell
types! Each of the cells below comes from the human body. Each contains the same genetic material but has very different structures
and functions.
Cell Type
1. Nerve Cell
2. Sperm Cell
3. Red Blood Cell
4. Muscle Cell
5. White Blood Cell
Main Function in the Body
Instructions: Use at least 1 complete sentence to answer the questions below.
1. What do all of these cells (except the red blood cell) have in common that makes them eukaryotic?
2. Which 2 kinds of cells would be expected to have a lot of mitochondria? Why?
3. Lipids help to lubricate and speed up electrical signals. Why would the long part of a nerve cell called the axon benefit
from being covered in lipids?

1. A stem cell is…
A. A cell taken from an embryo that can become any kind of cell type in the body
B. A cell taken from your intestines that can become any kind of tissue in the body
C. A kind of cell that can only become other kinds of similar cells
D. Any kind of cell that is undifferentiated and can divide to make new cells
2. An undifferentiated cell is…
A. A kind of stem cell
B. A cell without characteristics specific to a kind of tissue
C. Another term for a tissue-specific stem cell
D. Another term for a pluripotent stem cell
3. Using stem cells to replace damaged bodily tissue is called…

Practice
Instructions: Use at least 1 complete sentence to identify which organelle would be more abundant in each type of cell and
explain why.
Example: Human sperm cells use a lot of energy to move rapidly in order to reach the egg before they die. Based
on this information, which organelle would be more abundant in a sperm cell?
Answer: Sperm cells need to have more mitochondria because they need extra energy to travel quickly.
1. Bone cells must reproduce and make more bone cells on a regular basis in order to stay strong. Your bones are made
partially of a protein called collagen. Based on this information, which organelle would be more abundant in a bone cell?
2. One of the functions of the liver is the decomposition or break down of old, unneeded blood cells. Based on this
information, which organelle would be more abundant in a liver cell?
3. Muscle cells must expend or use a lot of energy in order to move your body. Remember, humans are animals, so
muscle cells are a type of animal cell. Based on this information, which organelle would be more abundant in a muscle
cell?
4. Plant cells must store excess or extra water so that they do not become flaccid or limp and dried out. Based on this
information, which organelle would be more abundant in a plant cell?
5. Plant cells also must keep a rigid structure, unlike animal cells. Based on this information, which organelle would be
more abundant in a plant cell?
