The equation for photosynthesis states that the combination of carbon dioxide, water and light energy produces a carbohydrate (glucose) and oxygen. The chemical formula is 6CO2 + 6H2O + light energy = C6H12O6 + 6O2.
Photosynthesis is the process through which organisms like plants absorb and convert light energy from the sun into chemical energy. The plants store this energy in the form of glucose.
In plants, photosynthesis takes place in the leaves that contain chloroplasts and stomata. While chloroplasts are types of plant cells, stomata are tiny openings in plant leaves that allow the exchange of gases like carbon dioxide and oxygen. The chloroplasts also contain other structures, such as chlorophyll, stroma, thylakoid and grana. These different structures have different functions in the photosynthesis process.
The photosynthesis process begins when the chlorophyll absorbs the light energy, the stomata take in carbon dioxide from the air and plants absorb water from stems. And the stroma, a fluid in the chloroplast, converts the carbon dioxide into sugar. The thylakoid and grana convert light energy into chemical energy.
Plants use the stored glucose to make food and then release oxygen into the atmosphere. The photosynthesis process takes place in two stages, which are the light-dependent reaction and the light-independent reaction.
