Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A) : Gymnosperms are characterized by the presence of naked seeds. Reason (R) : In gymnosperms, the ovules are not enclosed by any ovary wall and remain exposed both before and after fertilization. In the light of the above statements, choose the most appropriate answer from the options given below:
Options
- ABoth (A) and (R) are true but (R) is not the correct explanation of (A)
- B(A) is true but (R) is false
- C(A) is false but (R) is true
- DBoth (A) and (R) are true and (R) is the correct explanation of (A)
Correct answer
D. Both (A) and (R) are true and (R) is the correct explanation of (A)
Step-by-step solution
Assertion (A) states that gymnosperms have naked seeds, which is a true statement. The term gymnosperm itself means naked seeds (gymnos = naked, sperma = seeds). Reason (R) states that the ovules are not enclosed by any ovary wall and remain exposed both before and after fertilization. This is also true and provides the exact anatomical reason why the seeds (which develop from ovules post-fertilization) are naked. Therefore, both (A) and (R) are true and (R) is the correct explanation of (A). Answer: Both (A) and (
