During germination,which cellular structure will exhibit positive gravitrophism and grow downward?

Question

Quizplus · Accepted Answer

The embryonic root exhibits positive gravitrophism during germination, which means it grows in the direction of gravity and therefore grows downward. The embryonic shoot, on the other hand, exhibits negative gravitrophism and grows upward. The other choices, cotyledon, shoot, and seed nucleus, are not involved in the directional growth during germination.
