Photosynthesis is described as a chemical reaction because it involves the transformation of substances. Specifically, it converts carbon dioxide and water into glucose and oxygen, using light energy.
The process of photosynthesis can be represented by the chemical equation:
In this reaction, light energy is absorbed by chlorophyll and used to convert carbon dioxide and water into glucose, a form of chemical energy, and oxygen as a byproduct.
The conversion of light energy into chemical energy is a hallmark of chemical reactions, as it involves breaking and forming chemical bonds.
Photosynthesis is not limited to plants; it also occurs in algae and certain bacteria, which utilize similar mechanisms to convert light energy into chemical energy.
