प्रश्न
Answer the following question.
How do auxins promote the growth of a tendril around a support?
उत्तर
Auxin is a plant hormone that is synthesized at the tip of the root and shoot. It helps in the process of cell elongation. When a tendril comes in contact with a support, auxin stimulates elongation of the cells on the opposite side of the stimulus, which results in the formation of a coil around the support.
