Photosynthesis, computer artwork. Photosynthesis is the process by which most plants (as well as algae and some bacteria) convert sunlight into chemical energy. This energy is used to produce carbohydrate, such as starch, which is stored and used for growth. The process occurs in the green parts of the plant (especially the leaves). It requires water (absorbed by the roots, bottom left) and carbon dioxide (absorbed by the leaves). A by-product is oxygen, which is released through the leaves.

Science Photo Library was founded in 1981 by Michael Marten, one of the authors of "Worlds Within Worlds", a book exploring different ways to observe the universe - from electron micrographs, to images of earthrise taken from the Apollo spacecraft. When Marten started receiving requests for the beautiful images in the book, he had an idea of setting up Science Photo Library.
Since then, Science Photo Library has continued to work alongside world acclaimed photographers and the leading science and medical experts to provide a central source of the best science and specialist imagery available. Although the collection started with scientific images, it has grown to encompass all aspects of science and their impact on everyday life.
