| Cell Part | City Analogy | Purpose |
|---|---|---|
| G. Endoplasmic Reticulum | Roads or Highways | Transportation system |
| H. Golgi Bodies | Post Office or UPS | Packs & carries |
| I. Mitochondria | Power Plant | Provides power |
| J. Lysosomes | Recycling Plant or Waste Management | Recycle & waste disposal |
What part of a school is like rough ER?
Rough Endoplasmic Reticulum: The rough ER is like the school hallways because they transport proteins, just like the hallways are used for students to transport themselves between classes.
What is ER in cell city?
The endoplasmic reticulum (ER) is the site of synthesis of many proteins which will end up on the cell membrane, be exported from the cell or be sent to other specialised cell compartments. All endoplasmic reticulum consists of a complex interconnected series of flattened sacs or membranes.
What is the analogy for the ER?
The endoplasmic reticulum is like the highway system because the cell uses the endoplasmic reticulum to move material throughout the cell like people use highways to move throughout the country.
How is cell like a city?
The nucleus controls all of the activities of the cell as city hall controls all the activities in of the city. 2. The cell membrane is a thin, flexible envelope that surrounds the cell. The cell membrane controls what goes into and out of the cell as the city limits control what goes in and out of the city.
Why is the rough ER important to the cell?
Rough Endoplasmic Reticulum. The Rough ER is very important in the synthesis and packaging of proteins. The proteins synthesized on the surface of the rough ER are exported from the cell. These proteins contain special amino acid sequences called signal sequences.
What is a rough endoplasmic reticulum analogy?
Perhaps the clearest analogy that can be made to describe the role of the rough endoplasmic reticulum is that of a factory assembly line. Along its surface, which Dictionary.com describes as “rough” owing to the ribosomes arrayed along its membrane, proteins are synthesized and transported for use in the cell’s chemistry.
How is the rough ER similar to the smooth ER?
The rough ER is studded with various protein synthesizing ribosomes, whereas the smooth one is devoid of any ribosomes. It serves many different functions, including the facilitation of protein folding and processing into fixed sacs, which are known as cisternae, from where they are transported by the rough ER to the golgi complex.
What is the function of the ER in the cell?
The ER is the organelle that is responsible for processing these proteins, deciding what function they will serve, whether they will be needed inside the cell or outside. If required outside, they are transported by being packed into transport vesicles.
