Question

Assertion (A): Dry dehiscent fruits are usually single seeded.
Reason (R): Tridax fruit is cypsella with pappus like calyx.

• A. A and R are true and R is the correct explanation to A.
• B. A and R are true but R is not the correct explanation to A.
• C. A is true but R is false.
• D. A is false but R is true.

Hint:

Cypsella is a characteristic fruit of the Asteraceae family and includes a pappus for dispersal.

Answer 1

The Correct Option is D

Dry dehiscent fruits generally split open at maturity to release seeds and are often multi-seeded. Hence, the assertion is false. Tridax fruit is correctly described as a cypsella with a pappus that aids in wind dispersal, so the reason is true.
