Which best explains the role of plant pigments in photosynthesis?
A.
Produce photon energy
B.
Absorb light energy
C.
Provide electrons
D.
Convert heat to electricity
The correct answer is:
B. Absorb light energy
Explanation: Plant pigments, such as chlorophyll, are crucial for photosynthesis because they absorb light energy from the sun. This light energy is then used to drive the chemical reactions that convert carbon dioxide and water into glucose and oxygen. The pigments are responsible for capturing the light energy necessary for the photosynthetic process.
- A. Produce photon energy is not accurate as pigments do not produce photon energy; they absorb it.
- C. Provide electrons is partially true, but the primary role of pigments is to absorb light energy, which then leads to the generation of electrons.
- D. Convert heat to electricity is not related to the role of plant pigments in photosynthesis.
