Cells In A Hotel
Endo Retic is like hallways and elevator's because it distributes the proteins to needed places.
Ribosomes is like the chef in hotels that cook because they make proteins for people.
The generator because it has energy for the hotel to be active.
The manager because he/she controls the functions and the activies.
Everything in the hotel is 'Cytoplasm'. Because it lets the cells move through the hotel.
