Question: Organisms without a distinct nucleus are called?
Organisms without a distinct nucleus are called prokaryotes. Prokaryotes are the simplest and most ancient forms of life on Earth. They include bacteria and archaea, which are microscopic organisms that can live in a variety of environments. Prokaryotes have a single circular chromosome that contains their genetic information, and they lack membrane-bound organelles such as mitochondria or chloroplasts. Prokaryotes reproduce by binary fission, which is a process of splitting into two identical cells. Prokaryotes play important roles in the biosphere, such as decomposing organic matter, cycling nutrients, and producing oxygen.
