NEETBotanyPlant - Growth and Development
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Spraying juvenile conifers with gibberellic acids leads to early seed production. Reason (R): Gibberellic acids hasten the maturity period in juvenile conifers. In the light of the above statements, choose the most appropriate answer from the options given below:
Options
- ABoth (A) and (R) are correct but (R) is not the correct explanation of (A)
- BBoth (A) and (R) are correct and (R) is the correct explanation of (A)
- C(A) is correct but (R) is not correct
- D(A) is not correct but (R) is correct
Correct answer
B. Both (A) and (R) are correct and (R) is the correct explanation of (A)
Step-by-step solution
Assertion (A) is a correct statement as the application of gibberellic acids on juvenile conifers is known to result in early seed production. Reason (R) is also a correct statement. Gibberellins promote vegetative growth and hasten the maturity period in juvenile conifers. Because the maturity period is reached earlier, the plants transition to the reproductive phase sooner, which is exactly why early seed production occurs. Therefore, (R) is the correct explanation for (A). Answer: Both (A) and (R) are correct an
