The process by which plants make their own food is called as Photosynthesis.<div>

It is the process that takes place in the presence of light.

The site of photosynthesis is chloroplast and mainly occurs in leaves and other green parts of the plant.

In this process the plants use carbon dioxide and water as raw materials and prepares food in the presence of sunlight and chlorophyll.

The water is absorbed from the soil by the plant roots and carbon dioxide(CO2) is taken up from the air to prepare the food.
