Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): The placentation in Dianthus and Primrose is called free central. Reason (R): In these plants, the ovules are borne on the central axis and septa are absent in the ovary. In the light of the above statements, choose the most appropriate answer from the options given below:
Options
- ABoth (A) and (R) are correct and (R) is the correct explanation of (A)
- BBoth (A) and (R) are correct but (R) is not 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
A. Both (A) and (R) are correct and (R) is the correct explanation of (A)
Step-by-step solution
In Dianthus and Primrose, the placentation is free central. This type of placentation is defined by the condition where the ovules are borne on the central axis and septa are absent. Therefore, both the Assertion and Reason are correct, and the Reason provides the exact anatomical definition that correctly explains the Assertion. Answer: Both (A) and (R) are correct and (R) is the correct explanation of (A)
