The statement about photosynthesis that accurately describes the process is that carbon dioxide and water react with light energy to form photosynthates and release oxygen. During photosynthesis, which primarily occurs in the chloroplasts of plants, green algae, and some bacteria, light energy is captured by chlorophyll and used to drive a series of reactions that convert carbon dioxide and water into glucose (a type of photosynthate) and oxygen.

This process can be divided into two main stages: the light-dependent reactions, which capture and convert light energy into chemical energy in the form of ATP and NADPH, and the light-independent reactions (Calvin cycle), where the ATP and NADPH are used to convert carbon dioxide into glucose. The release of oxygen as a byproduct occurs during the light-dependent reactions when water molecules are split (photolysis).

The other statements about photosynthesis contain inaccuracies. While there are indeed stages in the photosynthesis process, stating there are three is not a standard characterization of its phases. The evaporation of water does occur as part of transpiration in plants but is not a primary mechanism or goal of photosynthesis. Regarding energy production, the net yield of ATP generated from photosynthesis is typically considered in the context of glucose synthesis, rather than
