Photosynthesis is the process that plants use to create energy from sunlight. This remarkable process occurs mainly in the chloroplasts of plant cells and involves the conversion of light energy into chemical energy. During photosynthesis, plants absorb carbon dioxide from the air and water from the soil, using sunlight to break down these substances. The result is the production of glucose, a form of sugar that serves as an energy source for the plant, and oxygen, which is released into the atmosphere. This essential process not only sustains plant life but also provides oxygen and food for countless organisms, including humans.
