Unit 3 Study Guide
Part 1: Cellular Theory and The History of the Cell
1. Look at the Pioneers of Cellular Theory Foldable. Describe how these scientists contributed to the discovery of
the cell.
A. Robert Hooke:
Improved the microscope’s lighting and was the first to name and discover cells using samples of cork
B. Anton Van Leeuwenhoek:
Shaped the lense in a microscope so the he could study microorganisms that he called animalcules (bacteria
and protozoa)
C. Matthias Schleiden:
Botanist who discovered different types of plants cells.
D. Theodore Schwann:
Zoologist who researched different types of animal cells
E. Rudolf Virchow:
Microbiologist who studied how bacteria reproduces.
2. What did Robert Hooke need in order to discover cells?
The microscope
3. Are viruses considered living things? Explain your answer.
No, they have to have a host cell in order to reproduce

Part 2 Cell Parts and Their Functions
1. Look at the chart of cell parts and their functions.
Name the organelles pictured and list
their functions:
1. Nucleolus
2. Nucleus
3. Ribosome
4. Peroxisome
5. Rough Endoplasmic Reticulum
6. Golgi Body
7. Cytoskeleton
8. Smooth Endoplasmic Reticulum
9. Mitochondria
10. Vacuole
11. Cytosol
12. Lyosome
13. Centrioles
14. What type of cell is this?
_Animal___
15. What organelle that is in your
notes is not labeled in this
diagram? _Cell Membrane_
2. How is the endoplasmic reticulum like a highway?
____It delivers materials into the nucleus________________
_______________________________________________________________________________________
3. How is the cell like a galaxy?
______Contains several parts that are working and interconnected to each other___________
_______________________________________________________________________________________
Use the notes on the differences of animal and plant cells to complete the Venn Diagram:
Animals Cells
1. Has smaller
vacuoles
2. Is flexible due to no
cell wall
3. No chloroplasts
Plant Cells
1. Has a
nucleus
2. Has a
membrane
3. Mitochondria
1. Have chloroplasts
2. Has a cell wall
3. Has a large
central vacuole
Part 3: Levels of Cellular Organization
Fill out the triangle using your notes on Organization of life, give an example for each level:
Organism, Example: whale, daisy
Organ System, Example: Digestive
System, Skeletal System
Organ, Example: Stem, skin
Tissue, blood
Cell
Example:
Amoeba
I found this on page ________ in my notebook.
