1. Why are there different pigments present in the chloroplast?

  • Because each pigment is a different colour
  • Because each pigment is located in a different part of the chloroplast and are thus in different conditions
  • Because each pigment absorbs different wavelengths of light
  • Because some pigments absorb infrared radiation
