Which of the following is the primary photosynthetic pigment that forms the reaction center in both Photosystem I and Photosystem II?
Show answer and explanation
Correct answer: Chlorophyll a
Chlorophyll a is the essential pigment that forms the reaction center, capable of converting light energy into chemical energy. Other pigments like chlorophyll b and carotenoids act as accessory pigments that harvest light and transfer it to chlorophyll a.
