Characteristics of Prokaryotic Cells

Prokaryotic cells are cells that do not have a true nucleus or membrane-bound organelles. Instead, their genetic material is located in a region of the cell called the nucleoid. This lack of a nucleus is a key characteristic that sets prokaryotic cells apart from eukaryotic cells.

In addition to the absence of a nucleus, prokaryotic cells also typically lack other membrane-bound organelles such as mitochondria, endoplasmic reticulum, and Golgi apparatus. Instead, they have a simpler internal structure with a cell wall, plasma membrane, ribosomes, and sometimes flagella for movement.

Prokaryotic cells are the foundation of organisms in the domains Bacteria and Archaea. They are found in a wide range of environments, from deep-sea hydrothermal vents to the human gut. Despite their small size and simple structure, prokaryotic cells play vital roles in various ecosystems and biochemical processes.
