PROCARYOTIC Meaning and
Definition
-
The term "procaryotic" refers to the category of organisms that fall under the taxonomic group called prokaryotes. Prokaryotes are typically single-celled organisms that lack a membrane-bound nucleus and other membrane-bound organelles. Unlike their eukaryotic counterparts, prokaryotic cells do not possess a definite nucleus or complex internal compartments. Instead, their genetic material, which is in the form of circular DNA, is freely floating within the cytoplasm.
Prokaryotes have a relatively simple cellular structure, consisting of a rigid cell wall that encloses the plasma membrane. They often have additional features such as pili, flagella, or capsules that aid in various functions like attachment, movement, and protection. Procaryotes are known to exhibit diverse metabolic capabilities and are found across various environments, including soil, water, and living organisms.
These organisms are classified into two main groups: bacteria and archaea. Bacteria are the more well-known group, encompassing a wide range of species with diverse shapes, sizes, and metabolic abilities. On the other hand, archaea were initially misclassified as bacteria due to their similar cellular structure, but they are now recognized as a distinct domain of life. Archaea often inhabit extreme environments such as hot springs, acid mines, and deep-sea hydrothermal vents.
In summary, procaryotic organisms are a large group of evolutionary diverse microorganisms that lack a defined nucleus and membrane-bound organelles. Their cellular structure and genetic material organization distinguish them from eukaryotic organisms.

Etymology of PROCARYOTIC
The word "procaryotic" is derived from the Greek prefix "pro-" meaning "before" or "primitive", and the New Latin term "cytus" meaning "cell". The term was coined by the American biologist Édouard Chatton in 1925 to describe a group of microorganisms whose cells lack a membrane-bound nucleus, which he contrasted with "eucaryotic" cells that possess a true nucleus. Over time, the spelling evolved to the modern "prokaryotic" to better conform to English orthographic norms.
