* Photo: This part comes from the Greek word "phos," meaning "light." Photosynthesis relies on light energy from the sun to power the process.
* Synthesis: This part refers to the building up or creation of a new substance. In this case, plants use light energy to synthesize complex sugar molecules (their food) from simpler substances like carbon dioxide and water.
Therefore, photosynthesis literally means "putting together with light." It perfectly encapsulates the process where plants use light energy to build their own food, a process crucial to life on Earth.
