Answer:
Start the reaction by absorbing light energy
Step-by-step explanation:
Photosynthetic pigments are substances present in the chloroplasts of autotrophic beings. They have the function of absorbing light, triggering the photochemical reactions of photosynthesis, a fundamental process for the maintenance of life on the planet. With this, we can say that the role of pigments in the photosynthesis reaction is to initiate the reaction by absorbing light energy.
The different pigments (chlorophylls and carotenoids) absorb different wavelengths of sunlight, which is the main energy source on the planet.
