Reproduction in Amoeba: Meaning, Process, and Key Facts

Biology /

Amoeba reproduces asexually through binary fission, a process in which the parent cell divides into two identical daughter cells. During this process, the nucleus of the amoeba first undergoes mitotic division, followed by the division of the cytoplasm (cytokinesis), resulting in the formation of two separate organisms. This method allows for rapid population growth under
