I am a college student who just bought a few plants to lighten and
brighten my room. I have noticed that they grow towards the light, and
while this makes sense for the plant, it makes very little sense to me.
Assume that a plant grows better when it's given the most light. Then
the side of the stalk that faces the light would grow the fastest,
causing the plant to dip away from the light. Why (or more accurately,
how) does this happen?
