The Next Steps
Thanks to Pasteur, scientists were starting to grasp the idea of biogenesis.

A1.8 French Chemist Louis Pasteur
Biogenesis stated that living organisms can only come from other living organisms. They do not emerge from non-living things.
These ideas lead the way for the development of the cell theory. The scientists that came after Pasteur were able to expand upon his ideas and his experiment to discover cells and their functions. We will look at these developments in the next lesson.

Interactive Activity
The Experiments
Work through this activity to review Redi and Pasteurโs experiments and Hooke and van Leeuwenhoekโs observations discussed in this lesson. These experiments were vital to the development of the cell theory and the study of biology. Print students can access the Experiments in the Online Resources for Print Students section of their online course.
