alleryMaximum photosynthesis occurs at:
AUV
BRed and blue light (peaks of chlorophyll absorption)
CGreen light
DYellow
Answer & Solution
Correct answer: B. Red and blue light (peaks of chlorophyll absorption)
Action spectrum peaks at red (~660 nm) and blue (~430 nm). UV damages chlorophyll. Green: minimum.
**White light:** all wavelengths combined → near maximum.
Indoor growers use red+blue LEDs for efficiency.
