Draw in sequence (showing the four stages), the process of binary fission in Amoeba.

The process of binary fission in Amoeba occurs in a sequence of four distinct stages. Since Amoeba is a unicellular organism with no fixed body orientation, this splitting can take place in any plane.

Sequential Stages of Binary Fission in Amoeba:

1. Stage 1: Parent Cell (Preparation)

• The parent Amoeba reaches maturity. It withdraws its pseudopodia, becomes rounded, and prepares for division with a distinct nucleus.

1. Stage 2: Karyokinesis (Nuclear Division)

• The nucleus of the cell begins to elongate. The genetic material (DNA) is replicated and distributed as the nucleus stretches.

1. Stage 3: Cytokinesis (Cytoplasmic Division)

• A constriction begins to develop in the cell membrane and cytoplasm. The elongated nucleus divides into two separate nuclei, each moving towards opposite poles.

1. Stage 4: Daughter Cells Formation

• The constriction deepens and completely pinches off the cytoplasm. This results in the formation of two independent, identical daughter Amoebae, each containing its own nucleus and cellular apparatus.
