Phun Physiology Phact #1
Plants sense gravity through starch particles stored in structures called Amyloplasts.

Haven't they grown plants aboard the space shuttle? I wonder how that went.

Art,
Yes, that and effects of light sensors cause the plants to grow upward as long as the light it "up". For the most part they're how the plant knows which way to grow their roots and shoots. Theoretically, if you grew a plant in a 100% light controlled environment with the lights "down" the stem will grow downward toward the light and the roots would grow "down" toward gravity.

Okay since we are talking the big gravity: Okay, now what is the term for sensing gravity in plants?
