1949: PHOTOSYNTHESIS LABORATORY

The video discusses the use of radioisotopes in studying photosynthesis at the University of California. It highlights how radioactive carbon is used to trace plant growth, aiming to uncover the process by which plants harness solar energy. This research could lead to enhanced crop production and address global food challenges.

What is the primary purpose of using radioisotopes in the study of photosynthesis?
