WebPhotosynthesis is a process in which plants use light, water, and carbon dioxide to produce sugars, water and oxygen. Chlorophyll a and chlorophyll b, in the chloroplasts of a leaf, are responsible for absorbing wavelengths of light for use in photosynthesis with red and blue wavelengths being optimal. Webreflected. This concept relates to photosynthesis because the chlorophyll pigments present in the thylakoid membrane absorb a specific range of wavelengths, which excludes the wavelengths of green light, which range from 500 to 570nm, and that is the reason why photosynthetic organisms appear green. If light waves are being reflected instead of …
