Photosynthesis is a process in which plants convert the solar energy, together with chlorophyll which is a plant pigment that gives to plants a green color, into chemical energy in the form of glucose, which represents the necessary energy source of plants. In this process, carbon dioxide is needed, and the result is the amount of glucose and oxygen that is released and has an immeasurable effect on air purification, so the importance of greenery is high. During photosynthesis, glucose does not transform into water, but chlorophyll together with solar energy leads to the formation of glucose and oxygen. Water is important for decomposition of rocks and particles, and thus provides minerals and nutrients for plants, as well as carbon dioxide necessary for photosynthesis.
The answer is: oxygen is formed along with glucose during photosynthesis.
