What is the result of the uneven growth of the tendril in response to touch?
Show answer & explanation
Correct answer: B
Explanation
The main result of the uneven growth of tendrils relative to the touch is that they wrap around the support and cling to it. When one part of the tendril touches an object, the cells on the other side grow faster, causing the tendril to bend toward the object and wrap around it, providing support for the vine.
Key results and mechanisms:
Asymmetric growth: Cells on the opposite side of the tendril grow faster than those on the opposite side of the contact.
Circular wrapping: Auxin hormones cause one part of the tendril to grow faster and the other slower, causing them to wrap around the support in a spiral manner.
Support and stability: This growth provides strong grip and mechanical support for the vine to climb.
