for Kevin Burt.
A plant bends toward the sun.
When light is not symmetric,
the hormone auxin,
from the Greek word αυξειν, to increase,
moves to the shaded side of the plant, elongating the cells on that side.
For those cells to be so pulled,
the auxin must stimulate elastins.
The elastins loosen the cell wall
on that dark side of the plant.
In this new flexible context the cells there then stretch,
and the plant curves,
exposing more of it
to the light that is
its life force.
It seems counter-intuitive.
I long assumed that it was those places in contact with light that reached most for it.
In order to survive, or to thrive even,
the dark side must be loosened, and then stretched.
And the commanding agent of that survival
is unevenly distributed within,
always found most in the darkest places.
