Cell Theory

Comparing Atomic Theory and Cell Theory

Reflect back to the Atomic Theory in Chapter 2:
a) every element is made of atoms
b) atoms of any element are the same
c) atoms of different elements can combine to form compounds
d) atoms are not made, destroyed, or changed in chemical reactions
e) the number and kinds of atoms remain the same in a compound

Add the 3 principles of the Cell Theory to your class notes

1. all organisms are composed of one or more cells
2. the cell is the basic unit of structure and organization in living organisms
3. all cells come from preexisting cells

A friend tells you he read somewhere that rotting garbage can turn into maggots, which are fly larvae, and the maggots can then grow into adult flies. What part of the cell theory could you use to refute (disprove) his claim?
