The answer is '<span>triploid cell'.

This occurs when two sperm nuclei reach the interior of a female gametophyte, where one sperm will fertilise the egg cell to form a zygote, whereas the other usually fuses with the binucleate central cell, forming a primary endosperm cell, effectively constituting an organism separate from the growing embryo. Approximately 70% of angiosperm species have polyploid endosperm cells which are typically triploid (containing three sets of chromosomes), but can vary widely from diploid(2n) to 15n.

What is mitosis? What is the importance of mitosis?

I am Lyosha [343]

Mitosis is important because it is essential for growth and repair in the body. Mitosis happens when a parent cell divides, creating two identical copies, referred to as daughter cells. During this process, it is essential that the daughter cells are exactly the same with the same copies of DNA.
