Question

Assertion (A): In some species of asteraceae and grasses, seeds are formed without fertilization.
Reason (R): Formation of fruit without fertilization is called parthenocarpy.

• A. ( \text{Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).} )
• B. ( \text{Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A).} )
• C. ( \text{Assertion (A) is true, but Reason (R) is false.} )
• D. ( \text{Assertion (A) is false, but Reason (R) is true.} )

Answer 1

The Correct Option is B

Assertion is true. In some species of the Asteraceae family (e.g., dandelions) and grasses, a form of asexual reproduction called apomixis can occur, where seeds are produced without fertilization. This results in offspring that are genetically identical to the mother plant. Reason (R) is also true. Parthenocarpy is the formation of fruit without fertilization. This process results in seedless fruits, such as in bananas and some varieties of grapes. However, Reason (R) is not the correct explanation of Assertion . Assertion describes apomixis, which is the formation of seeds without fertilization. Reason (R) describes parthenocarpy, which is the formation of fruits without fertilization. While both are forms of reproduction that bypass fertilization, they are distinct processes concerning different plant structures (seeds vs. fruits).
