Cells: An Analogy

This is an analogy of cells using animal cells. You probably may not have heard of some of the organelles.

Body: Earth

Organ: Country

Tissue: State

Cell: City

Cell membrane: City border with guards to monitor people entering and leaving the city

Free Ribosome: Individual shop

Ribosome on Rough Endoplasmic Reticulum (RER): Shop part of a franchise

RER: Franchise Headquarters

Smooth Endoplasmic Reticulum (SER): Recycling Plant

Vesicle pinched from RER: Transport vans for shop products

Vesicle pinched from SER: Transport vans for recycled products

Golgi Apparatus: Factory for processing, refining and modifying imported products

Vesicle fusing with Golgi Apparatus: Transport vans arriving and unloading goods

Vesicle pinching off from Golgi Apparatus: Transport vans with ready-to-go goods

Vesicle fusing with cell membrane: Transport vans unloading goods for export out of city

Cytoplasm: Free land

Nucleus: Government

Chromatins: High post officials

Centriole: Civil servants

Nucleolus: President/Prime Minister

Vacuole: Storage Plant

Mitochondria: Power Plant

If you happen to find that my analogy is incorrect at some parts, please let me know so I can change it. Thanks!
