Reproduction is an essential feature of all living organisms. It is the process by which an individual multiplies in number by producing more individuals of its own type.
Amoeba proteus does not reproduce sexually. The reproduction is essentially asexually and takes place by various methods such as binary fission, multiple fission and sporulation. Binary fission is the most common mode of reproduction. It results in the division of the parent Amoeba into two daughter amoebea. Amoeba reproduces by multiple fission during adverse environmental conditions.
Euglena has longitudinal binary fission. Paramecium has transverse binary fission and Plasmodium has multiple fission.
