Multiple Choice

A student collects a sample of pond water and looks at it under a microscope. The student notices a tiny organism swimming around. When the student observes its body more closely, they see that every part of the organism (its outer covering, inside structures, and moving parts) is made of cells.

Which part of the cell theory does this observation support?

• Cells come from pre-existing cells.

• Cells are the basic unit of structure and function of living things.

• Organisms are composed of one or more cells.

Multiple Choice
