I will use observatory skills to compare and contrast the similarities and differences between plant and animal cells in a well
organized paragraph
1-1 Conduct an investigation to provide evidence that living things are made of cells, either one cell or many different numbers and
types of cells
You need to prove to Mr. Anders that all living things are made out of cells:
-Use an onion to represent all plants
-Use a human to represent all animals

GROUP STATION!!!
Purpose: The purpose of this lab is to identify the similarities and differences between plants cells
and animal cells through a microscope investigation that shows plants and animals are made up of
cells.

Picture of cheek (animal) cells
Analysis:
Make a ven diagram analyzing (comparing and contrasting) the similarities and difference between
cheek and onion cells.

Conclusion: Write a paragraph explaining what you did in the lab and what you discovered about
plant cells and animals through using the onion and cheek cells as models.
In this lab, we looked through ______________________________________ at samples of _______________________
_______________ and ___________________________ ________________________. Through analyzing the microscope
slides, I have identified some similarities and differences between plant and animal cells. Plant cells
are different from cheek cell because they are________________________________________________________________

Place the cell you think
belongs to animals in the
top animal cell box, and
place the cell you think
belongs inside the plant
cell box. After Mr.
Awesome confirms, glue
the cells in and write
detailed observations of
each cell.
What do they look like?
