Plants are known as autotrophs. That means that they can make their own food. Plant cells do so by taking in gas and . Those are the used In the chemical reactions that occur during photosynthesis.
The gas that plants take in during photosynthesis is carbon dioxide (CO2), and the energy source they use is sunlight. Plant cells have specialized structures called chloroplasts that contain a pigment called chlorophyll. Chlorophyll absorbs sunlight, which is then used to convert carbon dioxide and water (H2O) into glucose (C6H12O6) and oxygen (O2). This process, known as photosynthesis, occurs in the chloroplasts and is essential for plant growth and survival. The glucose produced during photosynthesis serves as the primary source of energy for the plant and is stored in the form of starch.
