The generally accepted parts of modern cell theory include:
1. The cell is the fundamental unit of structure and function in living things.
2. All cells come from pre-existing cells by division.
3. Energy flow (metabolism and biochemistry) occurs within cells.
4. Cells contain hereditary information (DNA) which is passed from cell to cell during cell division
5. All cells are basically the same in chemical composition.
6. All known living things are made up of cells.
7. Some organisms are unicellular, made up of only one cell.
8. Others are multicellular, composed of countless number of cells.
9. The activity of an organism depends on the total activity of independent cells.
The cell theory cannot account for the first cells that had to divide to produce the next series of cells. So an exception is made stating that the the first cells did not derive from other cells.
So where did the first cells come from, may I ask?
