All About Photosynthesis

Organisms need energy to survive. Some organisms are capable of absorbing energy from sunlight and using it to produce sugar and other organic compounds such as lipids and proteins.

This process, called photosynthesis, is used by plants and some protists, bacteria, and blue-green algae. In photosynthesis, carbon dioxide, water, and sunlight are used to produce glucose, oxygen, and water. In plants, photosynthesis occurs mainly within the leaves. Since photosynthesis requires carbon dioxide, water, and sunlight, all of these substances must be obtained by or transported to the leaves for photosynthesis to occur.

Hello, I love your webpage. I have been researching solr power via You-Tube and other sources. I would like to se a solar power system that mimics plant photosyntheseis, if it could be engineered. To generate photo-voltaic electricity can be done, but to produce oxygen and possibly sugar as a by product would be a whole new field of science. After all, sugar is a food. I look forwar d to reading your releases. Thanks, Gae

YAWN – you miss the real interesting parts of photosynthesis, like the reduction and oxidation reactions of the co-factors, the crystal structures of the photosystems, the fundamental fact that the chloroplast is a symbiotic relationship formed eons ago that has persisted to this day (much to the dismay of the ingested prey though). the classical Z scheme…..oh photosynthesis is so much more than the light and dark reactions…..

And yes, don’t worry about it, but artificial photosynthetic systems are being researched, and the goal is an unlimited supply of hydrogen – one of the cleanest fuels we have today.
