About Nucleus Diagram Class 9

The nucleus houses a cell's genetic material (DNA) and directs nearly everything the cell does, from growth to reproduction. This model highlights its double membrane, nucleolus, and pores.

Why It's Important

  • Stores the genetic instructions for the whole cell
  • Controls which genes are switched on or off
  • Directs the cell's growth and repair
  • Passed on when cells divide

Observation Points

  • Notice the double membrane surrounding the nucleus
  • Locate the small nucleolus inside
  • Identify the pores dotting the nuclear membrane
  • Consider how tightly DNA must be packed to fit inside

Learning Objectives

  • Identify the main parts of the nucleus
  • Explain the role of the nuclear membrane and pores
  • Describe what the nucleolus produces
  • Understand why the nucleus is called the cell's control centre

Summary

The nucleus stores a cell's DNA and directs its activity, controlling everything from protein production to how the cell grows and divides.

NucleolusProduces ribosomes

How It Works

DNA inside the nucleus stores genetic instructions
↓
Instructions pass through nuclear pores as messages
↓
Ribosomes (made in the nucleolus) build proteins from those instructions
↓
The nucleus directs the cell's activity based on which genes are active
