The enteric nervous system (ENS)  is one of the main divisions of the autonomic nervous system (ANS) together with sympathetic and parasympathetic nervous system. This system consists of neurons that regulate the function of the gastrointestinal tract (GI).

7. Phytochrome prevents seeds of some plants from germinating when they are in deep shade by the: absorption of far-red waveleng
SIZIF [17.4K]
<h2>Function of Phytochrome </h2>

Explanation:

  • The <em>color of light</em> that they absorb maximally by the two types such as   <em>Pfr is a blue-green structure</em> that ingests far-<em>red light (730 nm)</em> and<em> Pr is a blue structure that retains red light (660 nm)</em>
  • <em>Pfr assimilates far-red light</em>, it is changed over to the <em>Pr structure</em>
  • Pfr can spontaneously revert to the Pr form  structure in obscurity <em>dark over time = dark reversion Pfr</em> is additionally helpless to proteinases
  • <em>Pfr contains  some red light, so in red light 15% Pr and   there is a parity of 85% Pfr.</em>
  • <em>The  phytochrome (Pr)</em> is changed over to the organically dynamic structure red light with the <em>Pfr under illumination</em>
  • <em>Darkness and Far -red light convert</em> the particle back to the inactive form.
