The structures that capture light energy in plants are commonly known as chloroplasts. These organelles contain chlorophyll, a pigment that absorbs sunlight during photosynthesis. Through this process, chloroplasts convert light energy into chemical energy, producing glucose and oxygen from carbon dioxide and water. This transformation not only fuels the plant’s growth but also serves as a primary source of energy for various organisms, underscoring the importance of chloroplasts in the ecosystem. Their ability to harness solar energy is fundamental to life on Earth.
