Answer:
Mitosis is a division of a eukaryotic cell in which the chromosomes are evenly distributed among the daughter cells.
In multicellular organisms, both sexual and asexual reproduction is followed by cell division, which ensures the growth and development of the organism. In addition, cell division is necessary to replace dead cells and repair injuries. New cells are constantly being added and old ones are being destroyed. About a hundred thousand more cells are created every second, and of course the same number dies. The new cells start with the division of the source cell. The cells formed in this way are called daughter cells. Stem cells can gradually divide into all the different cells in the body through mitosis.
Most of the body's cells are constantly renewed by mitosis, but there are also so-called irreplaceable cells that are formed only once in a lifetime for the life of the organism and do not regenerate by mitosis.

Answer:

The endosperm is formed through double fertilization where one male gamete nucleus with polar nuclei to form a triploid nucleus called the primary endosperm. The endosperm therefore will contain 15 chromosomes since the polar nuclei is diploid and the male gamete is haploid forming a triploid nucleus.
