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.
