You are studying the effects of artificial gravity on plant growth for NASA, and grow plants on a horizontal turntable that rotates (spins) fast enough to generate multiple g-forces (many times Earth's gravity) . Which way do the roots and stems grow?
A) The stem grows up against Earth's gravity, and roots grow in accord with Earth's gravity, independent of the g-forces generated by the turntable.
B) The stem grows toward the center of the turntable, and the roots grow away from the center, as the g-forces generated by spinning are greater than those due to gravity.
C) The roots grow toward the center of the turntable, and the stem grows away from the center, as the g-forces generated by spinning are greater than those due to gravity.
D) The roots grow up against the Earth's gravity, and the stem grows down, independent of the g-forces generated by the turntable.
