What is one defining feature of a prokaryotic cell?

Characteristics of Prokaryotic Cell

A defining feature of a prokaryotic cell is the presence of a nucleoid. Unlike eukaryotic cells that have a membrane-bound nucleus, prokaryotic cells have their genetic material present on a single chromosome within the nucleoid region.

Nucleoid: The nucleoid is a distinct region within a prokaryotic cell where the genetic material is located. It is not surrounded by a nuclear membrane like in eukaryotic cells, but instead, the DNA is found freely within the cytoplasm.

Other defining features of prokaryotic cells include the absence of membrane-bound organelles such as mitochondria, Golgi bodies, chloroplasts, and lysosomes. Prokaryotic cells also lack histone proteins that are important constituents of eukaryotic chromosomes.

The cell wall of prokaryotic cells is made up of carbohydrates and amino acids, providing structure and support to the cell.
