7. Which of the following best describes the relationship between cells and living things in general?

• All living things are made up of one or more cells.
• The number of cells in all living things is the same.

• Only groups of cells that function together are actually alive.

9. What sort of evidence must be gathered to support the idea that all living things are composed of cells?

• Comparisons should be made between non-living things and living things to determine any similarities in their structure.
• Samples of many kinds of living things should be examined under a microscope to identify the presence of cells.
• The functions of cells from many different living things should be monitored to see if they are identical.
• Non-living things should be examined to verify that the smaller parts of which they are composed are not cells.
