Answer:
A cell is the structural and functional unit of life which shows characteristic features like reproduction and cell division. The cell multiplication and reproduction serves many purposes to the organism and is mutually inclusive in prokaryotes.
The reproduction and cell multiplication serve many purposes to cell-like:
1. Maintain continuity of species: Reproduction ensures the continuity of the species on earth and should not become extinct.
2. Helps in the survival of organism: reproduction helps in the survival of the organism by transferring its heredity material to the offsprings.
3. Cell growth: the cell division helps in the growth of the organism.
<span>The similarities between an onion and whitefish cells exist in the cell division process. Normally the basic process of mitosis cell division is similar for plant cells and animal cells, but there are fundamental differences that mark the mitosis of plant and animal cells. Basic similarities of onion cell and that of whitefish embryo cell is that in the four phase of mitosis namely, Prophase, Metaphase, Anaphase and Telophase occurs in similar way. In Prophase for both cells the chromatin condensed and in metaphase the chromatin aligns in the center of cell and kinetochores of chromosomes attached with the microtubules of spindle from opposite poles. In Anaphase stage, the chromatids from the metaphase plate are separated and shifted to opposite poles.. Finally at Telophase, the cell divides via cytokinesis. The fundamental difference between Onion cells and Whitefish cells can be found in the process of cytokinesis.

Prokaryotes Virus, lol. That's the name of it.
It is the long string of amino acids.
