Which statement best describes the function of photosynthetic pigments in leaves?

• A. They store glucose produced during photosynthesis.
• B. They absorb light energy to initiate the process of photosynthesis.
• C. They transport water from roots to leaves.
• D. They provide structural support to the leaf cells.

Answer: (B)

Verified step by step guidance

1. Understand the role of photosynthetic pigments: Photosynthetic pigments, such as chlorophyll, are molecules found in the chloroplasts of plant cells. Their primary function is to absorb light energy from the sun, which is essential for driving the process of photosynthesis.
2. Clarify the process of light absorption: These pigments absorb specific wavelengths of light, primarily in the blue and red regions of the spectrum, while reflecting green light. This absorbed energy is then used to excite electrons, initiating the light-dependent reactions of photosynthesis.
3. Eliminate incorrect options: Review the provided options and eliminate those that do not align with the function of photosynthetic pigments. For example, pigments do not store glucose, transport water, or provide structural support.
4. Focus on the correct function: The correct function of photosynthetic pigments is to absorb light energy, which is then converted into chemical energy during photosynthesis. This energy drives the synthesis of glucose in the later stages of the process.
5. Conclude with the correct answer: Based on the explanation, the statement 'They absorb light energy to initiate the process of photosynthesis' best describes the function of photosynthetic pigments in leaves.
