The Nucleus

By January 13, 2006

Follow me on:

The nucleus is the 'control center' of a cell. It contains the cell's hereditary information (DNA) and controls the cell's growth and reproduction. The nucleus also controls the synthesis of ribosomes and proteins in the cytoplasm.

Looking at the nucleus from under an electron microscope, it appears as a distinct, circular object enclosed in a membrane. This membrane, called the nuclear envelope, separates the contents of the nucleus from the cytoplasm.

The nucleus is not the control center – it doesn’t direct anything. The nucleus contains the recipe for making molecules. Environmental factors dictate which recipe will be utilized. Thus, the environment could be considered the control center – if there is one.

The nucleus is the control center because it controls which proteins are made and when. Proteins do all the work in the cell. Thus–the nucleus is the control center.
