Photosynthesis is a complex biochemical process that allows plants, algae, and certain bacteria to convert light energy from the sun into chemical energy stored in glucose. The process primarily occurs in the chloroplasts of plant cells, where chlorophyll, the green pigment, captures light energy. The overall chemical equation for photosynthesis can be summarized as follows:
\[
6 \text{CO}_2 + 6 \text{H}_2\text{O} + \text{light energy}
