The diagram below represents a stage in cell division. Study the same and answer the question.
Name the parts labelled A, B, C and D.
A. Spindle fibers:
Spindle fibers are fibers found between the poles of a cell during cell division.
B. Cell wall:
The cell wall is the protective and semi-permeable outer layer of most plants, bacteria, fungi, and algae cells.
C. Sister chromatid:
The sister chromatids are DNA copies that are identical to one another. Each chromosome's centromere splits into two during cell division. The spindle fibers pull the two chromatids (sister chromatids) of a chromosome to opposite sides.
D. Centromere:
A centromere is a constricted section of a chromosome. Centromeres perform a crucial role in the formation of new cells. These centromeres function as a binding location for the two replicated chromosomes, known as sister chromatids, when the chromosomes are copied.
