NEET2019BotanySexual Reproduction in Flowering PlantsActual
Assertion : Parthenocarpy involves formation of seedless fruits. Reason : Apomixis occurs without fertilisation.
Options
- AIf both assertion and reason are true and reason is the correct explanation of assertion.
- BIf both assertion and reason are true but reason is not the correct explanation of assertion.
- CIf assertion is true but reason is false.
- DIf both assertion and reason are false.
Correct answer
B. If both assertion and reason are true but reason is not the correct explanation of assertion.
Step-by-step solution
Production and development of seedless fruits is called parthenocarpy. It is of two types, vegetative and stimulative. Apomixis is a mode of reproduction which does not involve formation of zygote through gametic fusion. It is, therefore, akin to asexual reproduction. In plants apomixis commonly mimics sexual reproduction but produce seeds without fertilisation e.g., some species of Asteraceae and grasses.
