Question

why is monera and protists are an exception to cell theory​

Answer 1

Explanation:

There is a debate as to whether or not viruses should be considered to be alive. The debate results from the fact that viruses cannot reproduce on their own. They must invade a host cell and utilise the host’s genetic material in order to reproduce.

The first cell did not come from another cell.

Mitochondria and chloroplasts have their own genetic material and can reproduce independently from the cell in which they reside.
