Photosynthesis:

This is the process by which green plants use sunlight to synthesize foods with carbon dioxide and water. It's like cooking food using only sunlight!

Chlorophyll:

Chlorophyll is a pigment found in plants that absorbs light energy for photosynthesis. It's like solar panels on houses absorbing sunlight to generate electricity.

Electron Transport Chain (ETC): ETC transfers electrons from electron donors to electron acceptors via redox reactions. It's like a relay race where electrons are the baton being passed along.
