Purpose

The nucleus controls the actions inside of the cell.

Function

The nucleus is the brain of the cell. It contains the DNA and RNA of the cell, which work together to build and control the cell. It produces protiens, which are carried by the endoplasmic reticulum to the various parts of the cell. These protiens are messages which give the cell orders. Like the mitochondria and chloroplasts, the nucleus is a small little cell within a cell. It has a double membrane, contains DNA, and manufactures protiens. However, unlike those other two organelles, the nucleus' protiens and DNA direct the rest of the cell. The membrane surrounding the nucleus is called the nuclear membrane. The "stuff" inside of the nucleus (besides the nucleolus) is called the nucleoplasm. Inside of the nucleus is is a round shape called the nucleoulus. Made up of protiens and RNA, the nucleolus helps in the formation of ribosomes.

Location

The nucleus is inside the cell membrane.
