Reproduction in Amoeba by Asexual Reproduction
Amoeba is a unicellular protozoa. Its mode of reproduction is asexual by fission and multiple fission.
Binary Fission
It occurs under normal condition in water when the organism grows to a particular size, the nucleus divides into two equal daughter nuclei and each of the daughter nuclei become enclosed by half of the protoplast leading to the production of two daughter cells. The cell division is simply mitotic.
Binary Fission in Amoeba
Multiple Fission
In some unicellular organisms such as amoeba, the cells rounds up to a cyst-like structure.
