$\underline{\textsf{DEFINITION}}$

Photosynthesis is the natural process by which green plants and some other organisms prepare their food (Glucose).

Raw Materials Carbon Dioxide and Water, in the presence of Sunlight and Chlorophyll, are converted into Glucose and by-product $\textbf{Oxygen}$ is released in the atmosphere.

________________________________

$\underline{\textsf{MECHANISM}}$

1) Light Energy of Sun is absorbed by Chlorophyll.

2) Light Energy is converted into Chemical Energy and the Water molecule splits into $\textbf{Hydrogen}$ and $\textbf{Oxygen}$.

3) Carbon Dioxide is reduced to form Carbohydrates(Glucose).
$\textbf{Oxygen is released into the atmosphere.}$
