Katarina [22]

The equation for photosynthesis is given as:

6CO₂ + 6H₂O ----> C₆H₁₂O₆ + 6O₂

<h3>Photosynthesis</h3>

Photosynthesis is the process by which green plants manufacture their food from carbon dioxide and water in the atmosphere using sunlight as an energy source.

Carbohydrates are produced while oxygen is given off as a by-product in photosynthesis.

During photosynthesis, the energy from the sunlight is trapped by the chlorophyll found in the chloroplast and used to energize the reactions involved in photosynthesis.

The equation for photosynthesis is given as:

6CO₂ + 6H₂O ----> C₆H₁₂O₆ + 6O₂
