The end products of photosynthesis are oxygen and glucose. Some carbohydrates are also produced -particularly sucrose and starch.
Photosynthesis is the process by which autotrophic plants manufacture their own food through the use of sunlight. In photosynthesis, plants absorb sunlight to help them break down water, carbon dioxide, organic and inorganic minerals, etc. All this is made possible by the presence of chlorophyll.
The glucose produced as a by-product of photosynthesis is reserved as a food store for autotrophic plants.
The oxygen produced during photosynthesis is a result of the sun’s oxidation of water molecules (H2O). The other by-products -hydrogen ions and electrons- are used to further break down the carbon dioxide and water molecules, converting plant nitrates and sulfates to proteins.
The breaking down of carbon dioxide happens during the “dark” stage of photosynthesis and depends on the amount of light the plant stores during the “light” stage.
