What is prokar?

Prokaryotes are unicellular organisms that lack a nucleus and other membrane-bound organelles. They are generally smaller and less complex than eukaryotes, which are organisms that have a nucleus and other specialized structures within their cells. Prokaryotes include bacteria and archaea, which are found in a wide range of environments, from soil and water to the human body. They are known for their ability to adapt and survive in a variety of conditions, and some are important in biotechnology, medicine, and industry. However, some prokaryotes can also cause disease in plants, animals, and humans.
