Louis Pasteur's experiments showed that bacteria did not grow in a flask unless they first entered from the surrounding environment. What part of the cell theory did this prove?

Cells arose from preexisting cells

Explanation:

The part of the cell theory that Louis Pasteur experiments proved is the part that says cells can only arise from preexisting cells through cell division.

Louis Pasteur was able to disprove the idea of spontaneous generation by showing that bacteria will only grow in a swan neck flask containing broth if they first entered from the surrounding environment. The discovery represented a testament to the fact that cells can only arise from previously existing cells as stipulated by the cell theory.
