What would the plasma membrane be in a city?
What would the plasma membrane be in a city?
The Cell Membrane is like a City border because it controls what goes in and out of the city. The Nucleus is like the City Hall of the City because it controls most of the city by sending out information that it needs to function. The jellylike area between the nucleus and the cell membrane is called the cytoplasm.
What can a plasma membrane be compared to in real life?
Analogy: The cell membrane can be compared to the front doors of a building because the front doors allow things to go in and out just as the cell membrane allows items to go in and out of the cell. Function: The jelly-like fluid that fills a cell and supports the organelles of the cell.
What is the analogy for the plasma membrane?
Cell Parts Analogy. The cell membrane controls what goes in and out of the cell. The cell membrane is like a screen door, because a screen door holds things out but lets air in.
What would smooth ER be in a city?
Smooth ER stores ions for later use and calcium for detoxifying substances. They can be similar to roads and highways in cities because vehicles are used to move things and people throughout the city. Rough ER can be seen as an exiting city highway and smooth ER as entering city highway.
What is the city of cell membrane?
| Cell Part | City Analogy | Purpose |
|---|---|---|
| A. Cell | City | Area with fixed boundary |
| B. Cell Membrane | City Limits | Surrounds & border |
| C. Cytoplasm | Environment | Inner space |
| D. Nucleus | City Hall | Controls the activities |
What is the cell city analogy for mitochondria?
Energy Plants
| Cell Organelles | City Analogies |
|---|---|
| Nuclear Membrane | City Hall Fence with security guard |
| Mitochondria | Energy Plants |
| Nucleus | City Hall |
| DNA | Original Blueprints or the city |
What can the mitochondria be compared to in a city?
The mitochondria supply the energy for the cell by transforming sugars into energy as does a power company produce energy for the city.
What can a cell membrane be compared to?
The cell membrane is like a security guard, because the cell membrane controls what goes in and out of a cell like a security guard controls who goes in and out of the gate.
What analogy can help explain how the plasma membrane works?
Since it’s made of water, a water balloon lends itself to an analogy easily. In this example, the water is like the cytoplasm. The thin plastic covering of the balloon is the cell membrane. Until you really throw the balloon, the plastic shifts with it.
What would Golgi apparatus be in a city?
The golgi apparatus would be the post office in cell city. Its main function in cells is to package molecules like fats and proteins . These materials can either be stored in the golgi apparatus, released to be part of the cell membrane, or released to travel to other parts of the body through active transport.
How is cell membrane like a city?
The cell membrane is a thin, flexible envelope that surrounds the cell. It allows the cell to change shape and controls what goes into and out of the cell a. 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.
Is the cell membrane the city of a cell?
The Cell Membrane is a boundary between the cell and the outside. It defines a cell’s shape. The Cell Membrane is the City Limits of Cell City because it defines the cell’s or city’s shape.
What is the difference between a cell membrane and a plasma membrane?
The term cell membrane refers to the boundary of the cell as a whole, the term plasma membrane refers to the boundary of the cell or that of an organelle within the cell. Here, then, it would be right to say that membrane-bound organelles are surrounded by a plasma membrane.
Why are plasma membranes important to plant cells?
It provides additional support to the cell, and it is why plant cells do not burst like animal cells do if too much water diffuses into them. Plasma membranes are selectively permeable (or semi-permeable), meaning that only certain molecules can pass through them. Water, oxygen, and carbon dioxide can easily travel through the membrane.
Which is part of the plasma membrane is hydrophilic?
However, parts of these proteins that are exposed to the inner environment of the cell (cytoplasm) and the outer surface of the membrane are hydrophilic (water-loving).
