Which of the following tissues, cells, or structures in flowering plants is a part of the sporophyte generation and therefore diploid? - generative nucleus - sperm -synergid -cell of endosperm - cell of an integument

Cell of and integument

Explanation:

When flowering plants reproduce by sexual reproduction, they form seeds contained into fruits. The fruit is derived from the maturation of the flower's ovary (female part) after fertilization.

A mature seed contains three generations:

In contrast, the generative nucleus and sperm cell are part of male gametophyte (pollen grain) and therefore haploids. Synergid cell is part of embryo sac, therefore belongs to female gametophyte and thus being haploid. Finally, cell of endosperm is usually derived from the fusion between a sperm cell and one of the two female gametes present within the embryo sac, thus being triploid.
