    How plants prepare their own food?


    Green plants can make their own food from simple substances like carbon dioxide and water present in their surroundings by the process of photosynthesis.

The leaves have green pigment called chlorophyll, which help it to capture the energy of the sunlight. So, leaves of green plants containing chlorophyll synthesize carbohydrates in the presence of sunlight, water and carbon dioxide. \[C{{O}_{2}}+{{H}_{2}}O\xrightarrow[Chlorophyll]{Sunlight}Carbohydrate\,(glu\cos e)+{{O}_{2}}(oxygen)\]
