Photosynthesis

What is one function of the other pigments besides chlorophyll, in the chloroplast?

• to block damaging wavelengths of light

• to absorb different wavelengths than the chloroplasts

• to provide different colors to the leaves

• to transfer energy to a separate photosystem beside the one using chlorophyll a and b.

What is the primary function of the light reactions of photosynthesis?

• To produce glucose
• To produce NADPH and ATP
• To use ATP
• To produce RuBP
