How do
Plants know which way to Grow?
Now What's Going On?
When the foil packet was opened, it was observed that the roots grew outward from the center of the turntable. Any leaf formation is toward the center of the turntable.
What happens here is we have fooled the seed. The rotatiing turntable creates a simulated gravity with an outward force. The roots are pulled toward the gravity (outward from the center of the turntable.) This happens because our simulated gravity pulls that plant chemical auxin toward the outside of the machine. Stems grow away from the auxin build up, while the roots grow toward it.
