<human>:  How do plants convert light energy into chemical energy?
<bot>: Plants convert light energy into chemical energy by a process called photosynthesis. During photosynthesis, chlorophyll located in the chloroplast of the plant cells use light energy to convert carbon dioxide and water into glucose (sugar) and oxygen. The glucose is then used as a food source for the plant and for respiration in which chemical energy is released and stored in the form of ATP molecules.
