Vedclass · Answer

(B) Auxin is a plant hormone synthesized at the shoot tip that promotes cell elongation.When a tendril comes in contact with a support,the concentration of auxin decreases on the side touching the support and remains higher on the side away from the support.This higher concentration of auxin on the side away from the support stimulates faster cell growth and elongation on that side.As a result,the side away from the support grows longer than the side in contact,causing the tendril to coil around the support.
