BBC - Botany A Blooming History (2011) Part 2 Photosynthesis

Series which tells the story of how people came to understand the natural order of the plant world, and how the quest to discover how plants grow uncovered the secret to life on the planet.

Part 2: Photosynthesis

The air we breathe, and all the food we eat, is created from water, sunlight, carbon dioxide and a few minerals. It sounds simple, but this process is one of the most fascinating and complicated in all of science, and without it there could be no life on earth. For centuries people believed that plants grew by eating soil. In the 17th century, pioneer botanists began to make the connection between the growth of a plant and the energy from the sun. They discovered how plants use water, sunlight and carbon dioxide to produce sugars - how, in fact, a plant grows. The process of photosynthesis is still at the heart of scientific research today, with universities across the world working hard to replicate in the lab what plants do with ruthless efficiency. Their goal is to produce a clean, limitless fuel and if they get it right it will change all our lives.
