What is the main effect of gibberellin?

Answer and explanation

Correct answer: Increasing stem growth

Gibberellin is a plant growth hormone. Its important school-level effect is promoting stem elongation, which increases the length and overall growth of shoots; it can also support processes such as seed germination. Therefore, option A is correct. Decreasing blood sugar is associated with insulin, increasing heartbeat is related to animal responses such as adrenaline, and sound detection involves sensory receptors and the nervous system.
