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 prescence of cells.

• The functions of cells from many different living things should be monitored to see if they are identical.

• Non-l;iving things should be examined to verfy that the smaller parts of which they are composed are not cells.
