Question

Study the following diagrams showing various stages of binary fission in Amoeba:

The correct sequence of these diagrams should be:

(A) I, IV, III, II, V

(B) I, III, IV, II, V

(C) I, II, IV, III, V

(D) I, II, III, IV, V

Answer 1

During binary fission, the nucleus of the parent cell elongates and divides initially. A constriction starts appearing on the cell membrane. It starts widening and finally divides the parent cell into two almost equal halves (daughter cells). The daughter cells are identical to the parent cell.

Hence, the correct option is B.
