Question

level 2 q1 what pigment molecule absorbs blue and red light to provide energy for photosynthesis? a. carotenoid b. chlorophyll c. melanin d. anthocyanin a. carotenoid b. clorophyll c. melanin d. anthocyanin

Explanation:

• Option A: Carotenoids absorb blue - green light, not blue and red light, so A is incorrect.
• Option B: Chlorophyll (note: there is a typo as "Clorophyll" in the option, but it should be Chlorophyll) absorbs blue and red light and reflects green light. It is the main pigment for photosynthesis, providing energy for the process.
• Option C: Melanin is a pigment in animals (like humans) related to skin color and protection from UV, not involved in photosynthesis.
• Option D: Anthocyanin is a pigment related to flower and fruit color, not a primary photosynthetic pigment that absorbs blue and red light for energy in photosynthesis.

Answer:

B. Chlorophyll (note: the option has a typo as "Clorophyll", but the correct answer is B)
