What Is A Nucleus?

The nucleus is the central information processing center in the cell. It is usually the largest and most prominent organelle and can be seen using an ordinary light microscope. It is usually spherical, about 10 micrometers in diameter and has a darker patch called the nucleolus.

The nucleus is enclosed within its own membrane, the nuclear membrane, or nuclear envelope. This, like all membranes in the cell is a lipid bilayer.

Inside the nucleus is the DNA of the cell. This complex molecule carries all the information, in coded form, that the cell needs to make a complete copy of itself in cell division. The genes in the DNA are also used as templates to make proteins and these, produced at different times and for different reasons, control all the activities of the cell. Most cells have a cell nucleus but there are exceptions. Red blood cells in humans and mammals lose their cell nucleus. They live only for 120 days and carry oxygen around the body ~ they don't carry out complex processes and don't divide ~ so nature has decided they can do without one when they are fully developed.

The word nucleus, pronounced as nukleas, refers to the essential or central part around which all the other parts are grouped or gathered around. The word is drawn from the Latin word "nuculeus". The word nucleus can mean a number of things in different fields. For instance in biology it can refer to a spherical protoplasmic structure that contains a cell's hereditary material and is located within a cell. In physics it refers to the positively charged core of the atom which contains its protons and neutrons and forms a major part of an atom's mass. In botany it refers to a seed's or a nut's central kernel. In astronomy the word nucleus is used to refer to the brightest central part of a galaxy or the head of a comet.

It controls what the whole cell does, it is like a main control

It stores genetic information in the cell.

Cell nucleus is in charge of everything around the cell like the boss

Functions of nucleus are:-
1.regulate cell cycles.
2.helps in transfer of characters from parents to offspring
3.it is the functional head of cell

The center of a cell. It is a membrane that holds the chromatin (DNA)

It gives energy  its the power house

The nucleus is like a head quarters that gives commands to the cell. A process that takes place there is when the DNA is transcripted into Messenger RNA for the manufacture of proteins. The nucleus also holds the DNA, and it gives energy out to the cell. It doesnt make the energy, but the energy is transported there, and its the nucleus' job to give it out to the cell. Does this help?

Direct the activity of the cell

It is a center of the plant cell and animal cell.

A nucleus is basically the brain it tells cells what to do and what job they do.
