Final answer:
As the concentration of sugar trapped within a leaf increases, the pigments produced is c. Carotenoid
Step-by-step explanation:
Carotenoids are a group of pigments that are responsible for the red, orange, and yellow colors in many plants and fruits. Carotenoids function as photosynthetic pigments that absorb excess energy in the thylakoid membrane and safely dissipate that energy as heat. They serve as a protective mechanism to prevent damage to the plant caused by excessive sunlight.
Each pigment has a unique absorbance spectrum, meaning that they absorb light at different wavelengths. Chlorophyll a and chlorophyll b are responsible for the green color of leaves, while carotenoids absorb in the short-wavelength blue region and reflect longer wavelengths, resulting in orange, red, and yellow colors. Therefore the correct answer is c. Carotenoid
