One day there was a little nucleus swimming in a little cell. His job was to control the other Organelles.

The next day there was a nucleolus, and his job was to keep secrets (Stores hereditary info (DNA)).

Then there was Chromosomes, and they are DNA and protein.

Then there was... The Endoplasmic Reticulim! and he transported proteins.

The Golgi Body came next and it packaged and moved proteins out of the cell.

Then came the cell membrane, it keeps all the cells contents intact.

Then came the cell wall and it provides support and protection for the cell kinda like a body guard.

Then the mitochondria came to give every body energy from O2.
