Assertion (A): The movement of tendrils around objects is due to differential growth rates in the part of the tendril that is away from the object.
Reason (R): Tendrils exhibit positive geotropism as they grow towards the ground.
  • a)
    If both Assertion and Reason are true and Reason is the correct explanation of Assertion
  • b)
    If both Assertion and Reason are true but Reason is not the correct explanation of Assertion
  • c)
    If Assertion is true but Reason is false
  • d)
    If both Assertion and Reason are false
Correct answer is option 'B'. Can you explain this answer?

  • The Assertion (A) is true because the movement of tendrils around objects does indeed occur due to differential growth rates, where the part of the tendril that is further from the object grows more quickly, allowing the tendril to curl around the object.
  • The Reason (R) is also true, as tendrils generally exhibit positive geotropism, which means they grow towards the ground.
  • Despite both statements being true, the reason provided does not explain the assertion regarding how tendrils move around objects.
  • Therefore, the correct answer is Option B.

Understanding the Assertion and Reason
The assertion and reason presented pertain to the behavior of tendrils in climbing plants. Let's break down both statements to clarify why option 'B' is the correct answer.
Assertion (A): Differential Growth in Tendrils
- The assertion claims that the movement of tendrils around objects is due to differential growth rates.
- This is true; tendrils respond to touch (thigmotropism), causing the side of the tendril that is away from the object to grow faster, leading to coiling around the support.
Reason (R): Positive Geotropism in Tendrils
- The reason states that tendrils exhibit positive geotropism by growing towards the ground.
- This is misleading; tendrils typically do not exhibit positive geotropism. Instead, they tend to grow in a manner that allows them to find support, which is more related to thigmotropism, not geotropism.
Relationship Between Assertion and Reason
- Both the assertion and reason are true statements, but the reason does not correctly explain the assertion.
- The movement of tendrils is primarily influenced by thigmotropic responses rather than geotropic tendencies.
Conclusion
- Therefore, the correct choice is option 'B': both Assertion and Reason are true, but Reason is not the correct explanation of Assertion.
This highlights the complexity of plant behavior and how different growth responses contribute to their survival and ability to climb.
