According to Reference.com, cellular organisms that do not have a distinct nucleus, such as bacteria, are called prokaryotes. They are distinct from the eukaryotes, which are the cellular organisms that contain a nucleus.Continue Reading
In the three domain system, which is used for classifying biological life, organisms in the Bacteria and Archaea domains are all prokaryotes, whereas organisms in the Eukarya domain are eukaryotes.
Red blood cells, while not considered to be prokaryotes, also do not have a nucleus. This helps them to maximize space inside the cell for haemoglobin, which is essential in the transport of oxygen. By comparison, white blood cells do contain a nucleus.Learn more about Cells
Prokaryotic cells are single cells that evolved before eukaryotes, which are organisms whose cells contain nuclei and organelles. A prokaryotic cell has no true nucleus or membrane-bound structures called organelles. Prokaryotic cells are usually bacterial species.Full Answer >
The nucleus is designed to govern and control everything that happens within the entire cell, which includes the process of cell division. The nucleus is enclosed by a protective membrane, and it consists of three components, which are the nucleoplasm, chromosomes and the nucleolus.Full Answer >
If the nucleus of a cell becomes damaged by a xenobiotic substance, it can prevent the cell from dividing and lead to other problems. In many cases, the damage eventually causes the death of the cell.Full Answer >
Prokaryotic cells lack a nucleus. Bacteria and members of the domain Archaea are prokaryotes, while plants, animals, protists and fungi are eukaryotes. Prokaryotic cells lack the membrane-bound organelles found in eukaryotic cells.Full Answer >
