Select the option that is true regarding the following two statements labelled Assertion (A) and Reason (R). Assertion (A): Sexual reproduction is essential in plants for maintaining the continuity of the species for many generations.
Reason (R): Sexual reproduction leads to genetic variation that enhances adaptability and evolutionary fitness.
This question asks to evaluate two statements, Assertion (A) and Reason (R), about sexual reproduction in plants.
Assertion (A) states that sexual reproduction is essential in plants for maintaining the continuity of the species for many generations. This statement is true. Sexual reproduction, through the generation of diverse offspring, allows plant populations to adapt to changing environmental conditions over time, ensuring their survival and continuity across generations.
Reason (R) states that sexual reproduction leads to genetic variation that enhances adaptability and evolutionary fitness. This statement is also true. The process involves combining genetic material from two parents, creating offspring with unique genetic combinations. This genetic variation is the raw material for natural selection, improving the population's ability to survive and reproduce in various environments.
The core of the question is whether Reason (R) correctly explains Assertion (A). Genetic variation, as mentioned in (R), directly enables plants to adapt to environmental challenges. This enhanced adaptability is precisely what allows species to maintain their continuity over many generations, as stated in (A). Therefore, the genetic variation produced by sexual reproduction is the underlying mechanism that ensures species continuity.
Thus, the option stating that both are true and (R) is the correct explanation for (A) is the correct choice.
