The diagram give alongside represents a stage in cell division. Study the same and answer the questions that follow:
(i) Identify the stage of cell division.
(ii) Name the parts labelled A, B, C and D.
(iii) What is the unique feature observed in this stage?
(iv) Where does this type of cell division usually occur?
(v) How many daughter cells are formed from this type of cell division?
(vi) Is the dividing cell shown a plant or an animal cell? Give a reason to support your answer.

Solution

(i) The stage shown in the diagram is anaphase because here the chromatids have already started moving towards the poles.

(ii) Part A is an equatorial plate, part B is a cell wall, part C is daughter chromosomes (chromatids) and part D is centromere.

(iii) In this stage, the two chromatids separate from the centromere and begin to move in opposite directions towards the poles.

(iv) This type of cell division usually occurs in somatic cells.

(v) Two daughter cells are formed from this type of cell division.

(vi) The dividing cell shown here is a plant cell, as cell wall is not present in an animal cell.
