Answer
a. Amoeba reproduces through simple binary fission. Amoeba reproduces asexually through binary fission. In this process of reproduction, a single Amoeba is divided into two similar daughter cells. It grows larger and one nucleus in the Amoeba splits and forms two nuclei. The amoeba is produced by the single parent.
In Leishmania, binary fission occurs in a definite orientation due to the presence of flagellum at the end of the cell. Hence, there is a specific plane in which the fission occurs, while Amoeba can undergo binary fission in any plane.
b. Malarial parasite or Plasmodium reproduces by multiple fission. Each Plasmodium cell divides its nucleus into many small nuclei followed by the division of the cell body to form many daughter cells with each cell obtaining one nucleus. This type of reproduction is called multiple fission.
