Question

Much like auxin in a stem causes it to grow upward, the auxin in which structure makes it grow downward?

Responses

flowers

roots

gametes

leaves

Answer 1

Answer :Roots

Explanation: Gravitropism is based on the redistribution of auxin in the elongation zone of the developing root. If the root is not growing vertically downward, then auxin accumulates in the lower parts of the root, inhibiting cell elongation and causing the root to bend in the direction of gravity.
