Photosynthesis
Gbogbo ọrọ náà
Almost all the food on Earth, and the oxygen you are breathing right now, can be traced back to one process happening in green leaves: photosynthesis. Plants capture the energy of sunlight and lock it into sugar, building food out of nothing more than carbon dioxide and water.
In this lesson you will learn exactly what photosynthesis is, the word equation you must know by heart, the role of chlorophyll, and, at Extended level, the balanced symbol equation. By the end you will be able to explain how plants make their own food and why that matters for every living thing.
Ebumnobi
- Describe photosynthesis as the process by which plants synthesise carbohydrates from raw materials using energy from light
- State the word equation for photosynthesis as: carbon dioxide + water → glucose + oxygen in the presence of light and chlorophyll
- State that chlorophyll is a green pigment that is found in chloroplasts
- State that chlorophyll transfers energy from light into energy in chemicals, for the synthesis of carbohydrates
- [Supplement] State the balanced chemical equation for photosynthesis as: 6CO + 6H O → C H O + 6O 2 2 6 12 6 2
