Abstract

The cell is the basic unit of life and is responsible for all the processes that occur within living organisms. It is a small, enclosed structure that contains a variety of molecules, including DNA, proteins, and lipids, that work together to maintain the cell's function. There are several types of cells in the body, each with unique structures and functions. The most basic type of cell is the prokaryotic cell. Prokaryotic cells are small and simple, lacking a distinct nucleus and other membrane-bound organelles. Instead, their genetic material is found in a single, circular molecule of DNA, known as a nucleoid. Prokaryotic cells are found in bacteria and archaea and are generally smaller than eukaryotic cells.
