Question

What piece of evidence would cause scientists to decide that the cell theory would need to be revised?

Answer 1

Answer:

Cells can come from nonliving objects

Explanation:

This is wrong.

Cells can only come from other cells. Non living things, like rocks or sand do not produce cells.

Answer 2

Answer:

Microscopic observations have shown that the cell is the smallest functional unit of life. We now know the various organelle (or organs) of an individual cell and how they work. For example, a bacteria is a single-cell organism and is capable of carrying out all its life process (growth, division, metabolism, etc.)
