1967. An educational documentary that presents the natural process by which sucrose is produced in plants. It follows the process of photosynthesis and the atmospheric cycle of oxygen and carbon dioxide in the air to show how plants provide fuel and energy for man. Intended for schoolchildren aged 11 and above and shown in classrooms all over the country. The BFI does have a safety copy and this is one that may show up elsewhere given that broadcast copies will have been common.
