What makes plant leaves green?
A. Chlorophyll reflects the full spectrum of light.
B. Chlorophyll reflects green light.
C. Chlorophyll reflects red and blue light.
D. Chlorophyll absorbs green light.
Chlorophyll is a pigment produced in chloroplasts, the organelles that carry out photosynthesis. It is responsible for absorbing sunlight to provide energy that can be used to synthesize glucose molecules.
Answer and Explanation:
The correct answer is (B) Chlorophyll reflects green light. Chlorophyll is a pigment that absorbs electromagnetic radiation corresponding to visible light and uses its energy to fuel photosynthesis. Specifically, it absorbs light at the red and blud wavelengths, and reflects green light. This means that when we look at a plant, we see high levels of green light reflected by the leaves. This, in turn, causes the plant to appear green.
