Why tepetum cell is binucleated

Tapetal cells consist of a large number of the nucleus and it is generally polyploidy in nature. Division of the tapetal cell takes place by mitosis and after mitosis cytokinesis does not take place and this type of mitosis is known as endomitosis and it results in the binucleate or multinucleate tapetum

Tapetal cells undergo endomitosis where the nucleus in the nuclear membrane divides but cytokinesis does not occur that’s why they are called binucleated
