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.
The nucleus is commonly considered the nerve center of the cell, and in many regards it acts as the brain of the cell. The nucleus is made of a nucleoplasm, which houses both the chromosomes and the nucleolus, a non-membrane bound structure.
According to HowStuffWorks, the nucleus moves the chromosomes about within the nucleolus as a network of filaments. This only occurs when the cell is not dividing. The chromosomes are the most important part of the nucleus since they contain all of the genetic information that determines the various characteristics of the organism. In addition to containing that information, the chromosomes are also the directors of every operation that is carried out by the cell.
The nucleus has various functions due to the fact that it controls everything that goes on within a cell. The most common function of the nucleus is glycolysis, which is the cell's process of breaking down glucose in a way to produce energy.
