What type of effect does auxin have in plants?
Answer and explanation
Correct answer: It affects plant growth
The governing concept is plant hormonal coordination. Auxin is a plant hormone that promotes cell elongation in suitable tissues and helps regulate growth responses such as phototropism, in which a shoot bends toward light. Hence option A is correct. Lowering blood sugar and increasing heartbeat are animal-regulation functions, while stopping respiration is not the normal role of auxin.
