A small piece of "material" was retrieved from a crime scene and
sent to the RCMP crime lab in Regina. Your job, as the head
investigator, is to thoroughly examine the material and identify
whether it is plant or animal. You must find as many factors that
support your findings as you can. The outcome of your analysis
will either convict or clear the suspect.
In the chart below, identify the characteristics that you would look
for to determine conclusively which the material is.
Plant (Cell) Material
Animal (Cell) Material
