1. Amoeba stops moving and rounds off. 2. The nucleus begins to divide. 3. The nucleus has divided and the cytoplasm starts to constrict. 4 & 5 The constriction continues to divide the cytoplasm. 6. The daughter amoebae separate. This is a form of asexual reproduction called binary fission. There is no evidence of sexual reproduction in this species of Amoeba.
The "parent" cell divides into two smaller copies of itself. The nucleus also divides into two. The cell membrane allows oxygen from the water the amoeba lives in to come into the cell and carbon dioxide to pass out of the cell. In this way, the amoeba "breathes."Thus after this division nothing will happen to the parent cell remain as it is.
