Migration is when animals move on a regular cycle. For example, caribou in the Arctic go south in winter and return in summer when it's warmer. Many birds migrate, such as geese and storks. Migration is the travelling of long distances in search of new habitat.
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.
