How do seeds know which way is down?
All plants can sense the direction of the gravitational field and orientate themselves accordingly. … In mature plants, phototaxis (growing towards the light source) overrides the gravitational impulse for the stalk and leaves, but the roots – and the seed while it is underground – rely on gravity for orientation.
Do seeds go up or down?
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: the radicle (seed root) will always grow downward, showing “positive geotropism,” while the shoot (plumule) will grow upwards (negative tropism).

How do seeds know when to sprout?
The seed has two hormones: abscisic acid (ABA), which sends the signal to stay dormant, and gibberellin (GA), which initiates germination. The push and pull between those two hormones helps the seed determine just the right time to start growing.
