Photosynthesis Overview
Photosynthesis is a fundamental process that converts light energy into chemical energy, sustaining life on Earth. It is the process by which plants, algae, and certain bacteria use sunlight, water, and carbon dioxide to create glucose (sugar) and oxygen.
The overall equation for photosynthesis is:
6CO2+ 6H 2O + light energy → C 6H 12O 6+ 6O 2
In this equation, carbon dioxide (CO 2) and water (H 2O) are converted into glucose (C 6H 12O 6) and oxygen (O 2) in the presence of light energy.
Role of Light, Water, and Carbon Dioxide
Light energy is essential for photosynthesis. It is absorbed by chlorophyll, a green pigment found in plant cells. The energy from the light is used to split water molecules into hydrogen and oxygen. The hydrogen is then used to combine with carbon dioxide to form glucose, while the oxygen is released as a byproduct.
Water is also essential for photosynthesis. It is used to split into hydrogen and oxygen, and the hydrogen is used to combine with carbon dioxide to form glucose.
Carbon dioxide is the third essential ingredient for photosynthesis. It is used to combine with hydrogen to form glucose.
