Photosynthesis is one of the most important biological processes on Earth. It's how plants, algae, and some bacteria convert light energy from the sun into chemical energy stored as glucose. This process requires three main ingredients: sunlight, water, and carbon dioxide.
The chemical equation for photosynthesis shows us exactly what happens. Six carbon dioxide molecules combine with six water molecules, using light energy, to produce one glucose molecule and six oxygen molecules. This balanced equation represents the fundamental transformation that powers most life on Earth.
Photosynthesis happens inside specialized structures called chloroplasts, which are found mainly in leaf cells. These chloroplasts contain chlorophyll, the green pigment that captures light energy. The process has two main stages: the light reactions that capture energy, and the Calvin cycle that builds glucose. This process is crucial because it produces the oxygen we breathe and forms the base of nearly all food chains on Earth.
To summarize what we've learned about photosynthesis: It's the amazing process that converts sunlight into chemical energy using carbon dioxide and water. Plants produce glucose for their own energy and release oxygen as a byproduct. This process happens in chloroplasts and is absolutely essential for supporting most life on our planet.

Photosynthesis consists of two interconnected stages. The light reactions occur in the thylakoids, where chlorophyll captures light energy to split water molecules, producing ATP, NADPH, and releasing oxygen. The Calvin cycle happens in the stroma, where the ATP and NADPH from light reactions are used to fix carbon dioxide and build glucose molecules.
