Welcome!Today we'll learn about photosynthesis. This lesson is designed to help you understand the key concepts of this process step by step.
What is Photosynthesis?Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesise nutrients from carbon dioxide and water. It’s essential because it provides energy for almost all life on Earth.
The Role of ChlorophyllChlorophyll is the green pigment found in plants that absorbs light energy. It is located in the chloroplasts and is crucial for photosynthesis to occur.
Quick check: What is chlorophyll’s role in photosynthesis?

Reactants of PhotosynthesisThe two main reactants of photosynthesis are carbon dioxide and water. Plants absorb carbon dioxide from the air through small openings called stomata and take in water through their roots.
Plants take in carbon dioxide through {{blank0}} and water through {{blank1}}.
