D
Ultraviolet light
Verified step by step guidance1
Understand that photosynthesis is the process by which plants convert light energy into chemical energy, primarily using chlorophyll.
Recognize that chlorophyll, the green pigment in plants, absorbs light most efficiently in the blue and red parts of the visible spectrum.
Identify the visible light spectrum, which ranges from approximately 400 nm (violet) to 700 nm (red) in wavelength.
Note that infrared light, microwave radiation, and ultraviolet light are outside the visible spectrum and are not effectively absorbed by chlorophyll for photosynthesis.
Conclude that the visible light spectrum is the part of the electromagnetic spectrum that drives the photosynthetic process in plants.
