Question

Louis Pasture determined that microscopic organisms only appeared in sterile broth if the broth was exposed to the air. He concluded that microscopic organisms were found in the air and contaminated the broth. Pasteur's findings contributed to which part of the cell theory?

Answer 1

Pasteur's findings contributed to the concept of biogenesis, which states that life arises from preexisting life.

Step-by-step explanation:

Louis Pasteur's findings contributed to the part of the cell theory that emphasizes the importance of cells as the basic units of life and that all cells come from preexisting cells.

By showing that sterile broth remained free of contamination unless exposed to air, Pasteur disproved the idea of spontaneous generation and supported the concept that microorganisms come from preexisting microorganisms.

This experiment provided evidence for the principle of biogenesis, which states that life arises from preexisting life.
