Each month, Simply Cells chooses one organelle (a tiny specialized structure that performs specific cellular functions) to honor and showcase. We’ll explain all parts of the organelle and tell you all about its contents and functions!
March’s Organelle: The Nucleus!!
The nucleus is a very important part of the cell; the nucleus is basically the command center of the cell. The nucleus stores genetic information and controls metabolic activities. The nucleus contains many things: chromatin, nucleoplasm, nucleolus, nuclear envelope, and nuclear pores. Chromatin (DNA and protein) is the genetic information that is stored in the nucleus. Right before cell division, the chromatin will coil to form chromosomes. The nucleoplasm is the semi-fluid material inside the nucleus. The darkened region that makes ribosomal RNA is the nucleolus. The nucleus is surrounded by a double membrane called the nuclear membrane. Openings in the nuclear membrane (called nuclear pores) allow rRNA to leave the nucleus and lets protein in.
The nucleus is a vital part of the cell and deserves recognition!!
