Hi 1A2,
I will be helping you in some ways like telling you information,etc..
so:
Photosynthesis is a series of enzyme-catalyzed steps for the conversion of light energy into chemical energy by living organisms. Its initial substrates are carbon dioxide and water; the energy source is light (electromagnetic radiation); and the end-products are oxygen and (energy-containing) carbohydrates, such as sucrose, glucose or starch. This process is arguably the most important biochemical pathway,since nearly all life on Earth either directly or indirectly depends on it. It is a complex process occurring in higher plants, algae, as well as bacteria such as cyanobacteria. Photosynthetic organisms are also referred to as photoautotrophs.
That's all
