Chlorophyll is:

Chlorophyll is:

• A. The pigment that gives photosynthetic organisms a green color
• B. The pigment that gives red color
• C. The pigment that gives brown color
• D. The pigment that gives yellow color

Answer: (A)

Chlorophyll is the pigment that gives photosynthetic organisms their green color because it reflects green light while absorbing blue and red wavelengths. It sits in the chloroplasts’ thylakoid membranes and acts as the main light absorber to drive the light-dependent reactions of photosynthesis, mainly as chlorophyll a and chlorophyll b. Other pigments, like carotenoids, can appear yellow to orange and become more visible when chlorophyll breaks down (as in autumn), or red pigments in some algae, but the typical green hue of healthy plants comes from chlorophyll.
