The document compares different organelles in animal cells to things in countries. It describes mitochondria as the cell's power plant, the cell membrane as security, cytoplasm as the people, the nucleus as the president, centrioles as factories, the endoplasmic reticulum as airplanes, chromosomes as a family business, the nuclear membrane as gates, the nucleolus as the government, ribosomes as a cement factory, the vacuole as jail, the Golgi body as the mail system, and the lysosome as the internet. Each comparison explains how the organelle and country thing are analogous in the functions they serve.
