Photosynthesis More Ecological Considerations 
Leaves absorb approximately 85% of Photosynthetically Active Radiation (PAR).
The Remainder is either Reflected or Transmitted. This is enriched in Green light. It is also enriched in near Far-Red light (700-750 nm).
Although this region of the spectrum is inactive in photosynthesis, it has profound effects on Plant Growth and Development! This involves the Phytochrome system and has Enormous Ecological significance which ranges from seed germination to overall growth form.
 Leaves absorb most of the light in the blue and red regions of the spectrum. Green light is reflected or transmitted, as is far-red light. |
