Question

Assertion : Nuclear endosperm is formed by subsequent nuclear divisions with or without wall formation.
Reason : Coconut is an example of such endosperm, where the endosperm remains nuclear throughout the development of the fruit.

• A. Both assertion and reason are true and reason is a correct explanation of the assertion.
• B. Both assertion and reason are true but reason is not a correct explanation of the assertion.
• C. Assertion is true but Reason is false
• D. Both Assertion and Reason are false
• E. Assertion is false but Reason is true

Answer 1

The correct option is B Both assertion and reason are true but reason is not a correct explanation of the assertion.

In free nuclear or nuclear type of endosperm the PEN undergoes multiple divisions with no or partially formed cell walls at a later stage of division.

This type of endosperm formation is observed in coconut, where the liquid or the coconut water is the free nuclear stage while the white layer formation is development of the cell wall

So, the correct answer is 'Both assertion and reason are true but reason is not a correct explanation of the assertion'
