Animal and Plant Cell Investigation
All living things​ are composed of ​cells​. Cells come in a variety of shapes and sizes, and cells perform different
functions. Although cells may appear different, they resemble each other because they share common structures.
In this lab you will look at two types of cells, a human cheek cell and an onion cell and see how they are similar
and how they are different.
Part 1: Animal Cell
1. Before we look at cheek cells, take a moment to mark which cell structures you EXPECT are in the
cheek cells.
Structure
Expect to see
in an animal
cell? (Y/N)
Why or why not?
Cell membrane
Yes
Animal cells need a cell membrane to
● Controls what goes in and out of the cell
● Holds the cell together
● Protects the cell
Nucleus
Yes
Genetic material is contained in the nucleus.
Chloroplasts
No
Chloroplasts are only in plants. Chloroplast convert sunlight into
nutrients.
Cytoplasm
Yes
Cytoplasm is the gel-like substance that holds all the parts of a cell in
place.
Mitochondria
Yes
All cells need energy. Mitochondria convert nutrients into energy.
Cell Wall
No
Cell walls are specific to plants because the cell wall provides protection
and structure.
2. Draw pictures of the cheek cell at both low and high power. In the high power drawing, label any
identifiable structures​.

Part 2: Plant Cells
3. Next we look at elodea cells which is a type of seaweed. Take a moment to mark which cell structures
you EXPECT are in the elodea cells.
Structure
Expect to see
in a plant cell?
(Y/N)
Why or why not?
Cell membrane
Y
All eurkaryotic cells have a cell membrane. Plant cells have a cell
membrane to
● Protect the cell
● Control what goes in and out
● Holds the cell together
Nucleus
Y
Holds the genetic information
Chloroplasts
Y
Chloroplasts convert sunlight into nutrients.
Cytoplasm
Y
Cytoplasm holds the parts of the cell in place.
Mitochondria
Y
Mitochondria convert nutrients into energy which plants need to grow.
2
Cell Wall
Y
Cell wall provides strength and structure.
4. Draw pictures of the cheek cell at both low and high power. In the high power drawing, label any
identifiable structures​.
Medium Power
High Power

5. How does the shape of the animal cell differ from the shape of the plant
cell? Why do you think the shapes are different?

6. What structures are you able to see in both types of cells?

7. Both plant cells and animal cells contain mitochondria, yet we could not see
them in the pictures. Does this mean they are not in these types of cells? Why
or why not? Explain your reasoning?

8. Make a claim about whether the picture below is a plant or animal
cell. Then support your claim with evidence and an explanation.
