Multiple Choice

Which kingdom is composed of prokaryotes?

Prokaryotes have cells that lack a true nucleus and membrane-bound organelles, with DNA located in the cytoplasm and typically simple cell structure. The kingdom Monera is the traditional group that collects these organisms because their defining feature is this lack of a nucleus. Protists and Fungi are eukaryotes, meaning their cells have a nucleus and more complex internal structures. Archaea are also prokaryotes, but in modern classifications they’re usually placed in a separate domain rather than in the Monera kingdom. So, Monera is the best match for prokaryotic organisms.
