• All organisms are made up of cells

• Cells came from other cells

• A cell is an indestructible particle

All cells have these in common EXCEPT

• cell membrane

• organ

What kind of cell is this?

• Eukaryotic
• Prokaryotic

The main difference between prokaryotic and eukaryotic cells? 

• Prokaryotic cells have a cell membrane but eukaryotic cells do not.
• Eukaryotic cells contain DNA in a nucleus while prokaryotic cells do not.
• Eukaryotic cells have flagella but prokaryotic cells do not.
• Prokaryotic cells contain membrane-bound ribosomes while eukaryotic cells do not. 

Animal, fungi, plant, and protist cells are all examples of which type of cell?

• Eukaryotic

• Prokaryotic

• Both prokaryotic and eukaryotic

When cells are damaged, new cells are created by cell division. How does the cell theory support this fact?

• It states that all cells have a nucleus which divides.
• It states that all living things are made up of one or more cells.
• It states that cells come from previously existing cells.
•  It states that the basic units of structure and function are cells.
