The discovery is considered an important ... In natural photosynthesis, however, four manganese atoms and one calcium atom are involved in the formation of O 2. Photosynthesis is a light-activated ...

This allows the plant to capture and store carbon dioxide until the Sun rises again, offering the light necessary to complete photosynthesis. Algae are widely thought to conduct half of the world ...

Most important is its role as a solvent for all the chemical reactions in cells. Light intensity affects the rate of photosynthesis. The light intensity fluctuates during the day, and will also be ...

Only the areas that have been exposed to light will photosynthesise and therefore test positive for starch, showing that light is necessary for photosynthesis ... this drawing show the areas ...

However, photosynthesis doesn't just drive the carbon cycle — it also creates the oxygen necessary for respiring organisms. Interestingly, although green plants contribute much of the oxygen in ...
