Question

The diagram below represents a stage during cell division. Study the same and then answer the question that follow:

a) Name the parts labelled 1, 2, and 3. 

b) Identify the above stage and give a reason to support your answer. 

c) Mention where in the body this type of cell division occurs. 

d) Name the stage prior to this stage and draw a diagram to represent the same.

Answer 1

(a) 1 – Centrosome 2 - Spindle fibres 3 – Chromatids 

(b) The stage described in the diagram is the late anaphase of mitosis in an animal cell. The stage can be identified by the presence of separated chromatids which are found at the two poles of the cell. The appearance of the furrow in the cell membrane classifies the stage as the late anaphase. 

(c) The division is mitotic division and this kind of cell division occurs in all the cells of the body except for the reproductive cells. 

(d) The stage before anaphase is metaphase.
