Summarize cell theory of human biology.

Summary should include the following basic tenets:

• All living things are made up of cells.
• The cell is the structural and functional unit of all living things.
• All cells come from pre-existing cells by division.
• Cells contain hereditary information that is passed from cell to cell during cell division.
• All cells have essentially the same chemical composition.
• All energy flow (metabolism and biochemistry) of life occurs within cells.

A cell theory summary should also differentiate between the classification of microbes to include bacteria, viruses, fungi, and parasites.

Process/Skill Questions:

• What is the structure of a human cell?
• What are the functions of a human cell?
• How are human cells different from plant and other animal cells?
