If you have questions about how to cite anything on our website in your project or classroom presentation, please contact your teacher. Through photosynthesis, the plant uses the stored energy to convert carbon dioxide (absorbed from the air) and water into glucose, a type of sugar. Other anthocyanins absorb light in the green portion of the spectrum, extending the range of light a plant can use. The rate of photosynthesis will start slowly under bright white light, and then increase in darkness. An increase in chlorophyll B is an adaption to the shade, as it allows the plant to absorb a broader range of wavelengths of light.
