The type of cell division that takes place in a Streptococcus but not in a human cell is binary fission.

Here's why:

* Streptococcus is a type of bacteria. Bacteria reproduce asexually through binary fission. In this process, a single bacterial cell replicates its DNA and then divides into two identical daughter cells.

* Human cells, on the other hand, reproduce through mitosis (for somatic cells) and meiosis (for gametes). These processes are more complex, involving multiple stages and ensuring genetic diversity.

Therefore, while both bacteria and humans undergo cell division, the specific mechanism differs, with binary fission being unique to bacteria like Streptococcus.
