Answer
Sugars are made in a leaf through the process of photosynthesis. This process takes place in the chloroplasts of leaf cells where chlorophyll absorbs sunlight. The absorbed light energy is used to convert carbon dioxide, which enters the leaf through stomata, and water, which is absorbed by the roots, into glucose (a type of sugar). The overall equation for photosynthesis can be represented as:
ightarrow ext{C}_6 ext{H}_{12} ext{O}_6 + ext{6 O}_2$$
Here, glucose is produced along with oxygen as a byproduct.
