In the context of the electromagnetic spectrum, which type of electromagnetic radiation provides the energy that drives photosynthesis in plants?

• A. Microwaves
• B. Infrared radiation
• C. X-rays
• D. Visible light (primarily red and blue wavelengths)

Answer: (D)

Verified step by step guidance

1. Understand that photosynthesis is the process by which plants convert light energy into chemical energy, primarily using chlorophyll pigments.
2. Recall that different types of electromagnetic radiation have different wavelengths and energies, and not all are effective for photosynthesis.
3. Identify that chlorophyll absorbs light most efficiently in the visible spectrum, especially in the red and blue wavelengths.
4. Recognize that microwaves and infrared radiation have longer wavelengths and lower energy, which are insufficient to drive photosynthesis effectively.
5. Note that X-rays have much higher energy but are not used by plants for photosynthesis; instead, visible light provides the appropriate energy for this process.
