By definition, photosynthesis is a metabolic process carried out by certain cells of autotrophic organisms, that is, those that have the capacity to make their own food, such as plants.
With this process, plants capture the energy of sunlight and transform it into chemical energy, to produce organic matter.
Photosynthesis takes place in 2 stages:
-
In the first stage the plants absorb water from the soil through the roots. Through their stems they transport it to their leaves. In these it meets the sunlight captured by chlorophyll, which breaks the water molecule, separating hydrogen (H) from oxygen (O₂).
- The other stage is capturing carbon dioxide. This provides the carbon and oxygen atoms that, together with hydrogen and stored energy, will form the glucose molecule, from which compounds are produced that are the basis of food for plants and other living beings.
Then, sunlight, carbon dioxide and water are needed for the photosyntesis, while oxygen is released to the environment.
