Quick Summary

Nuclear division in biology refers to the process by which a cell's nucleus divides. This is a crucial part of cell reproduction and growth. There are two main types of nuclear division: mitosis and meiosis.1

Mitosis results in two genetically identical daughter cells, essential for tissue growth and repair in multicellular organisms. Meiosis, however, is a specialized division that occurs during the formation of reproductive cells (gametes). It produces four cells, each with half the number of chromosomes as the parent cell, which is vital for sexual reproduction and genetic diversity.2345

Nutritional dependence of the embryo
As nuclear division ends, the amount of DNA per nucleus increases still further, a condition comparable with that in various plant- and animal-gland nuclei, presumably connected with the nutritional function of the endosperm. Nuclear division takes place at first without cell-wall formation so that a coenocyte…
