Question

question 13
what is the role of plant pigments in photosynthesis?
capture (harvest) light energy
synthesize atp
reduce nadp+
pump hydrogen ions (h+) from the stroma into the thylakoid space.

Explanation:

Plant pigments, like chlorophyll, absorb light energy. This energy is crucial for the light - dependent reactions of photosynthesis. The other options are functions of different components in photosynthesis. Synthesizing ATP is mainly done by ATP synthase. Reducing NADP+ is part of the electron transport chain in the light - dependent reactions but not the role of pigments. Pumping hydrogen ions is related to the establishment of a proton gradient, which is also part of the electron transport chain machinery rather than the pigment's role.

Answer:

Capture (harvest) light energy
