Nucleoid is an organelle of a prokaryotic cell that contains genetic information.
Further Explanation
Living organisms are classified as either eukaryotes or prokaryotes.
Eukaryotes
Eukaryotes are living organisms that contain a nucleus and other membrane bound organelles. The function of the nucleus being storage of genetic materials and also controlling all cellular activities.
Eukaryotes are either single celled or multicellular for organisms such as plants, animals, and fungi.
Prokaryotes
Prokaryotes are organisms that lack a nucleus and other membrane bound-organelles such as ribosomes, Golgi apparatus, endoplasmic reticulum, etc.
Genetic information in prokaryotes is contained in a nucleoid which is a concentration of DNA that lacks an enclosing membrane. Nucleoid contains large circular DNA that has genes that are required for the survival and reproduction of the cell.
Other Cellular organelles.
Nucleus
Nucleus is a type of cellular organelle found in eukaryotic cells whose function is to control all the cellular activities undertaken by the cell. Additionally, the nucleus house the DNA which carries the genetic material of an organism.
Mitochondrion
This is one of the cell organelle inside a cell. It is referred as the powerhouse of the cell, as it is where energy to drive all cellular activities is generated through the process known as cellular respiration.
Ribosomes These are organelles where the synthesis of proteins takes place through a process known as translation. They are found in the cytoplasm, either freely suspended or attached to rough endoplasmic reticulum.
Cell membrane It is a structure that encloses the cell contents in the cytoplasm from the external environment. It’s functions is to control materials entering in and out of the cell through selective permeability.
