📖 Comprehensive Note
The nucleus is a double-membraned organelle found in all eukaryotic cells. It is the largest organelle in the cell and functions as the control center for all cellular activities.
The nucleus serves as the storehouse of DNA, containing the genetic blueprint of the organism. Its structure includes a nuclear membrane, nucleolus, and chromosomes.
- Nuclear membrane: Double, porous membrane separating cytoplasm from nucleus.
- Nucleolus: Tiny spherical body inside nucleus, makes ribosomes.
- Chromosomes: Carry genetic information in DNA form.

Nucleus
is a double-membraned
organelle,
found in all eukaryotic cells
Chorus
Cell is the largest organelle,
which function as
the control centre
of cellular activities,
of the cell's DNA
La la la, uh yeah,
Verse 2
And by structure
the nucleus is dark
round, surrounded
by a nuclear membrane
uhhhhhhhh yeP yep
and forms a wall between
we've got to know this
Chorus
Cell is the largest organelle...
Outro
Within the nucleus
their are tiny spherical
bodies called nucleolus
it also carries an essential
structure called chromosomes
