Different pigments are involved in the process of photosynthesis, with each pigment absorbing a specific wavelength of light. The main pigments are chlorophyll a and chlorophyll b, but carotenoids play an important role, as well. Which of the following do you predict would happen if a plant did not have carotenoids? A less-specific spectrum of visible light would enter the cell and be absorbed by the chloroplast.
Electrons would not reach an excited enough state to drive the synthesis of ATP from ADP.
Excess light energy would not be absorbed, and the chlorophyll would become damaged.
Photons of light would not be carried from photosystem I to photosystem II.
