Question

what did louis pasteur contribute to the cell theory?

Answer 1

Pasteur became the first to show that living things come only from living things. He demonstrated that the microorganisms would grow in sterilized broth only if the broth was first exposed to air that contained their spores (reproductive cells). Pasteur's discoveries led to the development of the cell theory of the origin of living matter. The cell theory states that all life originates from preexisting living material. Pasteur also showed that although bacteria live almost everywhere, their spread can be controlled.
