Answer 1

Answer:

Start the reaction by absorbing light energy

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.

Answer 2

Answer:

Option A, Start the reaction by absorbing light energy

Explanation:

Chlorophyll is a green color pigment in plant that helps in entrapping sunlight. Being green in color, it absorbs the blue and red light and reflects the green light. The molecules of chlorophyll gains energy from sunlight and then jumps to higher energy levels by the process known as photo excitation. These excited molecules get ionized to further initiate the process of photosynthesis.

Hence, option A is correct.
