Prokaryotic vs. Eukaryotic Assessment Study Guide
KEY
1. Why would we use a microscope? To see things too small to be seen with the naked eye.
2. What are some obvious organelles we would see when looking at a cell under the
microscope? You could see the cell membrane, nucleus, cell wall, and cytoplasm.
3. The three parts of the cell theory:
 All organisms are composed of one or more cells.
 The cell is the basic unit of life in all living things.
 All cells come from other cells.
4. Three important scientists to remember:
Robert Hooke
1665
1st person to observe and name dead cells in cork.
Theodor Schwann
1839
Said the cell is the basic unit of structure in living things
Rudolph Virchow
1858
Said all living cells come from other cells
5. Cells are the structures that contain all of the materials necessary for life.
6. Prokaryotic cells- cells that do not have a nucleus.
Examples: bacteria such as Escherichia coli & Streptococcus pneumoniae
7. Eukaryotic cells- all organisms other than bacteria which all have a nucleus
8. Unicellular or Single Celled-an organism made up of only one cell.
9. Multicellular- an organism made up of one or more cells.
10. Organelles- parts of the cell that allow the cell to live, grow, and reproduce
11. Cytoplasm- fluid like substance inside the cell
12. Cell Membrane- a flexible layer that surrounds the cell, keeps the cytoplasm inside and
allow food in and waste products out.
13.Nucleus- only in Eukaryotic cells, contains the cell’s DNA and is the control center of the
cell, like the brain.
14.Cell Wall- a structure that surrounds the cell membrane of plant and bacteria cells.
Animal cells do not have a cell wall.
Be able to compare the differences between prokaryotic and eukaryotic cells.
Prokaryotic Cells
No Nucleus
No membrane-covered organelles

Cell Wall
The cell wall allows a plant to
have strength and support.
All cells have four things in common:
1. Cell membrane________________________________________________________
2.Organelles____________________________________________________________
3.DNA____________________________________________________________
4.Small size_____________________________________________________________
Circle answer: Human cells are (prokaryotic/eukaryotic) and (unicellular/multicellular).
True/False: Elephants are larger than humans because they have more cells.
