Plants synthesize their food through a process called photosynthesis. Photosynthesis is the process by which plants, algae, and some bacteria convert sunlight, carbon dioxide (CO2), and water (H2O) into glucose (a form of sugar) and oxygen (O2). This process takes place in the chloroplasts, which are specialized organelles found in plant cells.
The components required for photosynthesis are:
-
Sunlight: Sunlight is the primary source of energy for photosynthesis. Plants capture light energy using a pigment called chlorophyll, which is present in the chloroplasts. Chlorophyll absorbs light energy from the sun.
-
Carbon Dioxide (CO2): Carbon dioxide is obtained by plants from the air through tiny openings called stomata, mainly located on the leaves. CO2 is one of the essential raw materials needed for photosynthesis.
-
Water (H2O): Plants absorb water from the soil through their roots. Water is transported through the plant’s tissues and reaches the leaves, where it is used in photosynthesis. Water provides the necessary hydrogen and electrons for the synthesis of glucose.

Chlorophyll: Chlorophyll is the pigment that gives plants their green color. It is responsible for capturing light energy from the sun and initiating the process of photosynthesis.
During photosynthesis, sunlight energy is absorbed by chlorophyll, which powers a series of chemical reactions. These reactions convert carbon dioxide and water into glucose and oxygen. The glucose produced during photosynthesis serves as a source of energy for the plant and is used to build other organic compounds necessary for growth and development.
The overall equation for photosynthesis can be summarized as:
6CO2 + 6H2O + sunlight energy → C6H12O6 (glucose) + 6O2
