The following are Internet sites which contain significant collections of materials which can be used in the teaching of mathematics at the K. Explore how photosynthesis works by helping the process along in this game. NOVA Official Website Illuminating Photosynthesis. By Rick Groleau. Posted 1. NOVA. Photosynthesis in plants and a few bacteria is responsible for feeding nearly all life on Earth. It allows energy from the sun to be converted into a storable form, usually glucose, which plants use to grow and thrive. Photosynthesis also generates the oxygen that animals need to survive.
