•  Chlorophyll absorbs red and blue light most effectively and reflects green light more than other colours

Chlorophyll is a green pigment found in photosynthetic organisms that is responsible for light absorption

  • When chlorophyll absorbs light, it releases electrons which are used to synthesise ATP (chemical energy)

There are a number of different chlorophyll molecules, each with their own absorption spectra, however collectively:

  • Chlorophyll absorbs light most strongly in the blue portion of the visible spectrum, followed by the red portion
  • Chlorophyll reflects light most strongly in the green portion of the visible spectrum (hence the green colour of leaves)
