Question
Chapter 3, Problem 3WIO
Summary Introduction
To explain:
How would one differentiate between a prokaryotic cell, plant cell and an animal cell found at a crime scene.
Concept introduction:
The observation of differences in the structure of different cells can help determining their type. This can be done with the help of a light microscope and observing the cells at different magnifications.
