Chromosomes are thread like structures usually present in the nucleus that become visible only during cell divisions. Most chromosomes consist of two arms that extend out from a specialized region of DNA , called Centromere.

Anaphase
centromeres
Centromeres split during cell division in the mitotic phase called anaphase. As the sister chromatids are pulled apart towards opposite poles of the cell, the centromeres divide, forming individual chromatids that will become separate chromosomes in the daughter cells.
A chromosome that has two centromeres.
Centromeres.
The sister chromatids are held together by the centromeres. Each chromosome is made up of two sister chromatids.
The stage of mitosis when spindle fibers attach to the centromeres of sister chromatids is called metaphase.
Yes, plant cells have centromeres. Centromeres are specific DNA sequences located on the chromosome where the kinetochore assembles during cell division to help in the separation of chromosomes. These structures are essential for the proper alignment and segregation of chromosomes during mitosis and meiosis.
