Which of the following statements is/are correct?

(I)The predominant type of endosperm is nuclear type.

(II)Coconut water is the male gametophyte.

(III)Coconut possesses both free-nuclear and cellular forms of endosperm.

 I and III

The correct answer is Option (1) -  I and III

The correct statement is:

The predominant type of endosperm is nuclear type and  Coconut has both free-nuclear and cellular types of endosperm.

Explanation:

I. The most common type of endosperm is the nuclear endosperm .

II. Coconut water, also known as liquid endosperm, is not the male gametophyte. It is the clear liquid found inside the cavity of a young coconut. It serves as a source of nutrients for the developing embryo within the coconut.

III. Coconut is unique in its endosperm composition. It exhibits both free-nuclear and cellular types of endosperm. The free-nuclear endosperm is present in the liquid form, while the cellular endosperm consists of cells containing nuclei. Both types of endosperm contribute to the nourishment of the developing coconut embryo.

Therefore,  statement I and  III are correct.
