How then does a seed know which way is up? The radicle (seed root) will always grow downward, showing “positive geotropism,” while the shoot (plumule) will grow upwards (negative tropism). All plants can sense the direction of the gravitational field and orientate themselves accordingly. It all comes down to gravity. The plants are sensing gravity. However, said sophie farkas, a molecular physiologist at the university of freiburg, the molecular mechanisms that amyloplasts use to signal which way is down have only recently. Plants have the uncanny ability to send their roots down and their shoots up, even if the seedlings are rotated. In nature, most seeds end up facing any old way and they still germinate. Geotropism (geo = ground, tropism = growth) takes care of assuring they sprout correctly: How do seeds know which way to grow?
