Quizplus · Accepted Answer

Auxins are plant hormones that play a crucial role in coordinating various growth and behavioral processes in the plant's life cycle. One of their key functions is to inhibit the growth of lateral buds (a phenomenon known as apical dominance), which restricts the formation of branches. This allows the plant to focus its growth upwards towards the light, rather than spreading outwards.
