1- Seven Characteristics of Living Things
• Breathing
• Eating
• Moving
• Excreting
• Reproducing
• Growing
• Reacts to the environment

Cell
• 3-All living organisms are composed of cells.
• 4-The cell is the smallest living unit that exist.
Smallest Unit

How do cells work?
11- Inputs: are substances that enter the cell and are indispensable to its activities.
12-Outputs: Substances that must leave the cell=Waste.

• How does it operate?• Who protects the city?• Who runs the city?• How does the city manage its trash?• How does the city get food?• How does the city get its power?• How do you know when you are in the
city limits?
![Page 15: The Cell!!!! TB:pgs. 277-285. 1- Seven Characteristics of Living Things Breathing Eating Moving Excreting Reproducing Growing Reacts to the environment.](https://reader035.fdocuments.net/reader035/viewer/2022062518/56649ebf5503460f94bca678/html5/thumbnails/15.jpg)
• Do the parts of the cell compare to any parts of a city?
• What cell parts do you remember from yesterday?
• How many can you relate to the parts of a city?
![Page 16: The Cell!!!! TB:pgs. 277-285. 1- Seven Characteristics of Living Things Breathing Eating Moving Excreting Reproducing Growing Reacts to the environment.](https://reader035.fdocuments.net/reader035/viewer/2022062518/56649ebf5503460f94bca678/html5/thumbnails/16.jpg)
• Each part of the cell has its own function or purpose.
• The parts of the cell can be compared to the parts of a city based on their similar purpose.
![Page 17: The Cell!!!! TB:pgs. 277-285. 1- Seven Characteristics of Living Things Breathing Eating Moving Excreting Reproducing Growing Reacts to the environment.](https://reader035.fdocuments.net/reader035/viewer/2022062518/56649ebf5503460f94bca678/html5/thumbnails/17.jpg)

• You are going to create your own real or imaginary city.
• Each part of your city will correspond to a part of the cell.
• Your city must have: • a name• a border• a ruler (mayor, king,
queen)• make a product• have a way to deliver the
product• power system

• An analogy is a similarity between like features of two things, on which a comparison may be based.
Endoplasmic Reticulum
The road represents the
endoplasmic reticulum because
they are both transportation
systems

Choose an Animal Cell City or a Plant
Cell City
The plant cell will have two extra parts:
Cell WallChloroplasts
You will receive an extra 2 points if you choose the plant cell.

1. Sketch your city in pencil on large computer paper.
2. Label and circle each part of the city 1. A-I for plant cell2. A-G for animal cell
3. Create a legend in the corner of your city.4. Color your city completely and neatly

• Your map/picture must be neat, colorful, correctly labeled, and have a legend or key.
• Use pencil first then color. • Be creative! Have fun with it. • Past examples included
• underwater cities• prehistoric cities• skate parks• amusement parks

1- Exchanges Between the Cell and Its Environment
• Diffusion• Osmosis• Photosynthesis• Cellular Respiration
![Page 27: The Cell!!!! TB:pgs. 277-285. 1- Seven Characteristics of Living Things Breathing Eating Moving Excreting Reproducing Growing Reacts to the environment.](https://reader035.fdocuments.net/reader035/viewer/2022062518/56649ebf5503460f94bca678/html5/thumbnails/27.jpg)
Diffusion2 – Diffusion is the
process by which molecules spread from areas of high concentration, to areas of low concentration.
3- When the molecules are even throughout a space - it is called EQUILIBRIUM
![Page 28: The Cell!!!! TB:pgs. 277-285. 1- Seven Characteristics of Living Things Breathing Eating Moving Excreting Reproducing Growing Reacts to the environment.](https://reader035.fdocuments.net/reader035/viewer/2022062518/56649ebf5503460f94bca678/html5/thumbnails/28.jpg)
Osmosis
4- Osmosis is the passage of water across a membrane that only allows certain substances to pass
![Page 29: The Cell!!!! TB:pgs. 277-285. 1- Seven Characteristics of Living Things Breathing Eating Moving Excreting Reproducing Growing Reacts to the environment.](https://reader035.fdocuments.net/reader035/viewer/2022062518/56649ebf5503460f94bca678/html5/thumbnails/29.jpg)
Osmosis cont.
6-Selectively Permeable Membranes allow some things across the membrane. For example water and oxygen move freely across the cell's membrane, by diffusion
5-The solute is more concentrated on the right side to start with. This causes molecules to move across the membrane toward the left until equilibrium is reached.
