Question

There are two statements marked as Assertion (A) and Reason (R). Choose the CORRECT answer. Assertion (A): A calyx is called persistent if it remains attached to the fruit. Reason (R): Persistent calyx is characteristic of plants with epigynous flowers. (A) (B) (C) (D)

• A. Both (A) and (R) are true and (R) correctly explains (A).
• B. Both (A) and (R) are true but (R) does not explain (A).
• C. (A) is true but (R) is false.
• D. (A) is false but (R) is true.

Answer 1

Answer:

C. (A) is true but (R) is false.

• A calyx is persistent when its sepals remain attached to the fruit after flowering, providing protection as seen in tomatoes and eggplants. ​ Why (R) is False Persistent calyces occur across various flower types, including hypogynous (tomato, Solanaceae) and perigynous flowers, not exclusively or characteristically in epigynous flowers where the ovary is inferior. The persistence depends on genetic programming rather than gynoecium position. ​
