Photosynthesis in plants takes place faster in:

  • (A) Yellow light
  • (B) White light
  • (C) Red light
  • (D) Darkness
In fact, the white light consists of all wavelengths but Red light is commonly said to be the most productive individual color in photosynthesis. This is due to the fact that red photons possess the precise energy level which most effectively excited chlorophyll molecules. The plants absorb the red light the most and hence they have the greatest quantum yield that is, the light energy is converted into chemical energy with the lowest amount of waste. Blue light is also very absorbed but it contains more energy which is normally outgassed as heat and thus, red light is the "sweet spot" in the photosynthetic process in terms of speed and efficiency.
