Question

Choose the correct order of the stages of binary fission in Leishmania.

(I)	(II)	(III)	(IV)	(V)

Options

• I, II, III, IV, V

• I, III, II, V, IV

• I, III, V, II, IV

• I, II, III, V, IV

Answer 1

I, III, II, V, IV

Explanation:

In Leishmania binary fission occurs in a definite orientation:

1. A constriction in the cell membrane first appears after nuclear division. 
2. Inwardly transversely from the centre of the dividing cell, the membrane expands. 
3. The cytoplasm divides into two equal pieces, each with a single nucleus
4. The daughter cells can split off and create two new creatures.
