Answer:
A photosynthetic cell within a plant leaf produces chemical energy, stored within glucose molecules.
Explanation:
The energy captured from sunlight by Photosystems in chlorophyll is used to split a water molecule and reduce carbon dioxide to carbohydrates. This energy from sunlight is therefore stored in the chemical bonds of the glucose molecules. It is thereafter harnessed during cellular respiration when the chemical bonds of glucose are broken and the energy transferred to make ATP molecules.
