A endoplasmic reticulum is like a shipping company because the shipping company send packages to the city just like the endoplasmic reticulum sends proteins all overthe cell
A pipeline carrying milk in a dairy would be an analogy for ER.
Factory
The endoplasmic reticulum can be likened to a highway system within a city. It transports proteins and other materials throughout the cell, just as vehicles transport goods and people along roads. The rough endoplasmic reticulum, with its ribosomes, is like a busy highway with factories (ribosomes) producing goods (proteins) for distribution.
An everyday object that is similar to endoplasmic reticulum would be a road. Trucks travel on the road like the proteins travel through the endoplasmic reticulum. Assembly line, digestive track or airplane route could be used too.
The Smooth Endoplasmic Reticulum is found within the cytoplasm of eukaryotic cells, serving various functions such as lipid and steroid hormone synthesis, detoxification, and calcium storage. It is not a physical location within a city, but rather a cellular organelle present in living organisms.
Cell Wall- probably be like a city wall surrounding the city, protecting it and defining the boundaries (osmotic control, protection, mechanical support). Cell Membrane- this would be the guards just inside the city wall, controlling who can enter and leave the city (selective permeability). Nucleus- this would be like, parliament i guess...a group deciding what should happen inside the city (control centre). Ribosomes- this is the industrial area of the city, creating building materials to extend and develop the city (proteins). Rough Endoplasmic Reticulum- these are couriers who collect the materials from the industrial site and take it to where it is needed (carry proteins). Smooth Endoplasmic Reticulum- another industrial site which creates packages to send and communicate with other cities (steroids). Mitochondria- the electricity generator which creates energy for the city (ATP). Golgi Apparatus- the postal system of the city, collecting, processing and transporting (molecules) around and out of the city. Chloroplasts- the food manufacturing plant in a city! Plasmodesma- roads connecting the cities along which communication can occur. Lysosomes- units of military personnel, who can attack and invaders (bacteria) and those who do not work properly (unwanted organelles) and kick them out of the city. (turning out to be a bit of a right-wing city here! :S) Cytoplasm- this is the general streets and landscape of the city, where all these things (metabolic reactions) take place! Sap Vacuole- a large compound where many useful substances which might be needed in the city are stored.
Basically, it performs the synthesis and modification of proteins and their shipping to the Golgi for further modification (O-glycosylation, for instance ), then the Golgi is the shipping department of the cell.. The smooth ER has to do with the modification of lipids and carbohydrates, and detoxification of the cell.----------------------------------------------------------------The Endoplasmic Reticulum as a whole works to compartmentalize the cell by weaving into sheets all across the cell. The portions of the ER studded with ribosomes (labeled Rough) synthesize proteins while the portions without ribosomes (labeled Smooth) synthesize lipids. Basically, if you compare a cell to a city, the endoplasmic reticula are the roads in which materials can be processed and moved around inside of the cell.It has ribosomes inside which make and sort proteins (also known as synthesis). Rough endoplasmic reticula synthesize proteins, while smooth endoplasmic reticula synthesize lipids and steroids, metabolize carbohydrates and steroids, and regulate calcium concentration, drug detoxification, and attachment of receptors on cell membrane proteins.---There are two parts of the endoplasmic reticulum; the smooth and the rough. The endoplasmic reticulum has several general functions, one being the facilitation of protein folding and the transport of synthesized proteins in cisternae. Only proteins that are folded properly are transported into the Golgi complex from the rough Endoplasmic Reticulum. The "ER" also attaches oligosaccharides in a process called Glycosylation.

Imagine a cell as a small city. Nucleus = Government headquarters (manages other organelles) Endoplasmic Reticulum = a factory that builds protein packages. Ribesomes = Are protein packages. Golgi Body = Sorts and sends the packages off through the cell. Lysosomes = Waste management that recycles waste.
The smooth endoplasmic reticulum (SER) can be likened to a highway system within a city. It is involved in lipid and steroid synthesis, like a city's factories producing goods. Just as highways transport goods throughout the city, the SER transports these synthesized molecules to where they are needed in the cell.
