Answer:
The correct answer is cytokinesis.
Explanation:
The process of differentiating a cell into two daughter cells is known as the cell cycle. It is categorized as S (synthetic), M (mitotic), Gap 1 and Gap 2 phases. During the cell cycle, the cell goes through cellular procedures like genetic duplication, growth, and division.
The central cell (n+n) refers to a diploid cell that amalgamates with a sperm cell to produce a triploid (3n) mass and further gives rise to endosperm. The secondary nucleus or the central cell possesses two polar nuclei in a single cell.
In angiosperms at the time of the generation of female gametophytes, one nucleus from each pole goes towards the center and combines to produce a secondary nucleus. In the mentioned case, the essential step of mitosis, which would get stopped to produce (n+n) central cell would be cytokinesis.
An n+n central cell would be produced from mitosis if cytokinesis does not take place.
After the successful migration of sister chromatids to the opposite poles followed by their condensation and the appearance of the nuclear membrane around them, the cytoplasm divides to make each structure at the opposite pole an independent entity - daughter cells.
The division of the cytoplasm successfully ends the mitotic process. If this particular step does not occur, it means that a multinucleated (n+n) cell would result instead of two independent daughter cells.
