[10m] Indole-3-acetic acid is the best known example of what class of plant hormones, which can promote cell elongation by activating proton pumps?
ANSWER: auxins
[10e] Auxins are responsible for the suppression of ethylene production, which inhibits the lateral type of this general process. Plants generally do this process in the direction of sunlight.
ANSWER: growth [accept growing or other word forms; accept descriptions of getting taller or bigger]
