Q. Which of the following statement(s) is/are correct?
I. The presence of a triploid endosperm nucleus is a distinctive feature of gymnosperms.
II. In gymnosperms, endosperm represents the female gametophyte.

Q. 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.

Q. Assertion :In Cocos nucifera, coconut water represents the cellular endosperm and the surrounding white kernel represents the free-nuclear endosperm. Reason: Endosperm is always completely consumed by developing embryo before seed maturation.

Q. Identify the correct pair of statements.
(i) White kernel of Coconut is a free nuclear endosperm
