This one is easy. Evolutions in nature is passive and cruel; the plants
find things out by either propagating themselves or dying with no progeny.

Plants produce slightly differing flowers all the time. The ones looking
more attractive to the pollinators set more seed, the ones looking ugly
(to the pollinators), do not. Eventually the ugly ones die out.

Roots may be able to seek water by growing by sensing higher humidity, and
growing in that direction (evolution took care of those who tried to grow
them elsewhere). I may be wrong here...
