During photosynthesis, radiant (or light) energy is converted into chemical energy, specifically in the form of glucose (sugar). This process primarily occurs in the chloroplasts of plant cells, where light energy is used to convert carbon dioxide and water into glucose and oxygen, following the general equation:
\[ 6 \text{CO}_2 + 6 \text{H}_2\text{O} \xrightarrow{\text{light}} \text{C}6\text{H}{12}\text{O}_6 + 6 \text{O}_2 \]
Here, \( \text{C}6\text{H}{12}\text{O}_6 \) represents glucose, and the process releases oxygen as a byproduct.
