Binary fission in Leishmania.
In Leishmania, binary fission occurs in a definite orientation :
1. Nuclear division is followed by the appearance of a constriction in the cell membrane.
2. The membrane then grows transversely inward from near the middle of the dividing cell.
3. Cytoplasm separates into two equal parts, each with one nucleus.
4. The two daughter cell may separate from each other and behave as two independent organisms.
