Answer
The leaf produces glucose through the process of photosynthesis. During this process, the leaf absorbs carbon dioxide from the air and water from the soil, using sunlight as the energy source. Chlorophyll, found within the chloroplasts of the leaf cells, captures light energy to facilitate this reaction, converting carbon dioxide and water into glucose and oxygen.
