Here's how it works:
* Sunlight is absorbed by chlorophyll in plants.
* This energy is used to split water molecules (H2O), releasing electrons and oxygen (O2).
* The electrons are passed through an electron transport chain within the chloroplast.
* This process releases energy that is used to phosphorylate ADP (adenosine diphosphate) into ATP.
* ATP is the energy currency of cells, providing the energy needed for other processes like sugar production.
So, while sunlight is the initial source of energy, it's ATP that carries and transfers this energy within the plant cell to fuel the process of photosynthesis.
