Multiple fission is an asexual reproduction in which parent organism splits to form many new organisms at the same time.
a) Sometimes during unfavorable conditions, a protective wall or cyst is formed around the cell of a single celled organism.
b) Inside the cyst, the nucleus of the cell splits several times to form many smaller nuclei called daughter nuclei. Each nucleus gathers a bit of cytoplasm around itself, develops a membrane around each structure.
c) Thus many daughter cells develop which on liberation grow into adult organisms at the same time.
Plasmodium is a protozoan which reproduces by asexual method of multiple fission.

There are four tiny organisms A, B, C and D. The organism A is a parasitic protozoan which causes a disease known as kala-azar. The organism B is a microscopic single-celled animal which causes malaria disease in human beings. The organism C is a unicellular animal which can change its body shape according to need, it has no fixed shape. The organism D is also a unicellular animal which is slippet-shaped having a large number of tiny hair all around its body.
