alleryWhich statement best explains why light wavelength matters?
ANot all wavelengths support photosynthesis equally
BOnly infrared light supports plants
CAll wavelengths are absorbed identically
DWavelength never affects leaf activity
Answer & Solution
Correct answer: A. Not all wavelengths support photosynthesis equally
Photosynthetic action depends on wavelength and pigments, so wavelengths differ in effectiveness.
