Which process underlies the thigmotropic behavior of a green bean tendril?

B) rotation of the tendril in response to a biological clock
C) extra proliferation of cells on the shaded side of the tendril
D) slower growth on the side where an object is touching the tendril

Question

Quizplus · Accepted Answer

Thigmotropism is the growth or movement of a plant in response to touch or physical contact. When a green bean tendril comes into contact with an object, it exhibits thigmotropic behavior by growing more slowly on the side that is touching the object, allowing the other side to grow faster and thus causing the tendril to coil around the object for support.
