Here's why:
* Prokaryotic: These organisms lack a nucleus and other membrane-bound organelles within their cells.
* Unicellular: They are single-celled organisms.
* Monera: This kingdom encompasses bacteria and archaea, which are both prokaryotic and often unicellular.
It's important to note that the classification of life is constantly evolving. While "Monera" is a traditional term, some modern classifications have shifted away from it.
