  • descriptionAbstract

    The sun is by far the most important source of energy for all organisms on Earth.  Light is the medium through which an organism receives information about its environment.  It contains information that tells a plant when to grow, when to flower, and when to pro-duce fruit.  For radiant energy to have a biological effect, it must be absorbed by a photoreceptor.  Plants have photosystems to pro-cess energy and information.  The sun emits a continuous spectrum of radiant energy, but more than half is lost as a result of refrac-tion and difraction in the upper atmosphere, and by reflection off of clouds and particles suspended in the air.  Only radiation with wave lengths between 300 and 1000 nm, the so-called “biological window,” influence life processes.

    Keyworks: Light receptors, light morphogenesis, plants, light.
