The green color in plants indicates the presence of chlorophyll, the vital pigment responsible for photosynthesis. Chlorophyll absorbs sunlight, primarily in the blue and red wavelengths, while reflecting green light, which gives plants their characteristic color. Through photosynthesis, plants convert carbon dioxide and water into glucose and oxygen, using sunlight as energy. This process is fundamental for plant growth, providing the energy necessary to fuel metabolic activities. Additionally, chlorophyll plays a crucial role in overall plant health, as it enables plants to harness energy from sunlight and contribute to the Earth’s oxygen supply and food webs.
