6. ANS:
The cell theory states that all living things are composed of cells. It also says that cells are the basic units of
life and new cells come from preexisting cells. The cell theory is significant to biology because all living
thing are made of cells. Differences in the structure and function of different life forms are reflected in
differences in their cell structures.
