what is nucleus

The nucleus is a dense, membrane-bound organelle present in eukaryotic cells. It acts as the control center of the cell and contains the genetic material called DNA.

The nucleus controls important activities such as:

• Cell growth

• Metabolism

• Protein synthesis

• Cell division

Main Parts of the Nucleus

Part	Function
Nuclear Membrane	Protects the nucleus
Nucleoplasm	Jelly-like substance inside nucleus
Nucleolus	Produces ribosomes
Chromosomes	Carry genetic information

Characteristics of Nucleus

• Usually spherical in shape

• Present in plant and animal cells

• Surrounded by a double membrane

Importance of Nucleus

• Stores hereditary information

• Controls cell functions

• Helps in reproduction and inheritance

In conclusion, the nucleus is the control center of the cell that contains DNA and regulates all major cellular activities.
