Question

How does an Amoeba reproduce?

Accepted Answer

Binary fission in Amoeba:

Lower organisms such as Amoeba replicate binary fission. The single-cell divides into two halves. Since Amoeba does not have a fixed shape, the division of the cell can take place either laterally or longitudinally. When the cell divides, the nucleus of the cell grows completely before they split equally. The daughter cells grow completely before they split into two different entities. The daughter cells formed are the exact copies of the parent cell.

Multiple fission in Amoeba:

Multiple fission at the cellular level occurs in many protists. Multiple fission occurs in Amoeba to survive and reproduce under unfavourable conditions. When conditions are unfavourable, the Amoeba withdraws its pseudopodia and becomes almost round.

It secretes hard coverings and forms a cyst. Inside the cyst, the nucleus divides repeatedly to form many nuclei. This followed by the division of cytoplasm. This leads to the formation of new daughter cells. When favourable conditions return, the cyst bursts and release new daughter cells.
