This is a short, not perfect, explanation---
In essence: the part of the stem away from light elongates faster
then the part of the stem in light, making it grow "bent".
This process is influenced by plant hormones which control
cell elongation, and light receptors which turn on/off the
effects. Some sources think that light actually destroys or
prevents the formation of these hormones.
