Chlorophyll and beta-carotene complement each other in photosynthesis. In this part of the video, the functions of beta-carotene are discussed. It supports chlorophyll in capturing light, but also protects against too much light. Prof. Dr. Tausch and Rebecca Grandrath of the Bergische Universität Wuppertal explain how this works by availing themselves of lab experiments, models and animated diagrams.
