1. Notes: Cells, Osmosis & Respiration
TB:pgs

2. Review: Seven (+ 1) Characteristics of Living Things

3. Example #1: whales Breathing: O2 Eating: Krill Moving: Swimming
Excreting: Urine, CO2
Reproducing: Live Young
Growing: From 1m+
Reacts to the environment: Fear
Made of cells yes
In conclusion, whales meet all criteria and are therefore living

4. Example #2: ferns Breathing: CO2 Eating: Minerals Moving: Cellular
Excreting: O2
Reproducing: Pollination
Growing: Seed-plant
Reacts to the environment: Wilt
Made of cells: Yes
In conclusion, ferns meet all criteria and are therefore living

5. Example #3: Car Breathing: O2 Eating: Gas Moving: Rolls Excreting: CO2
Reproducing: No
Growing: No
Reacts to the environment: Rusts
Made of cells: No
In conclusion, a car does not meet all the criteria, and therefore, is not living.

6. Starting Point: Cells
All living organisms are composed of cells. The cell is the smallest living unit that exist. Cells do not have all the same size, shape, or function. There are two different cell types: plants and animal cells

7. Nucleus
Endoplasmic
Reticulum
Cytoplasm
Cell
Membrane
Mitochondrion

8. Cell Wall
Vacuole
Endoplasmic
Reticulum
Cell membrane
Mitochondria
Cytoplasm
Nucleus
Chroroplasts

9. Functions of Cells Organelle Where? Function Nucleus Animal + Plant
Controls all cell’s activities, including reproduction and growth
Cytoplasm
Distributes nutrients in the cell
Cell membrane
Decides what comes in and out
Surrounds and protects cell
Vacuole
Storage (energy, waste)
Mitochondrion
Energy producing
Endoplasmic reticulum
Network of canals (for nutrients)
Chloroplasts
Plant only
Involved in photosynthesis
Cell wall
Supports the cell

10. How do cells work? Inputs: Outputs:
Substances that enter the cell and are indispensable to its activities.
Outputs:
Substances that must leave the cell (Waste)

12. Think of a City 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?

13. Now think of a Cell
Do the parts of the cell compare to any parts of a city?
What cell parts do you remember from last year?
How many can you relate to the parts of a city?

14. A cell can be compared to a city!
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.

15. Cell City Analogies
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

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

17. Creating your own Cell = City
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

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

19. Final Product
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
Make sure to include a description on a paper.

20. Some examples…

21. City = Cell
Brick Wall = Cell Wall
Gate = Cell Membrane
Air = Cytoplasm
City Hall = Nucleus
Police Station = Nuclear Membrane

22. A I C D G B H E J
Legend A: Far Far Away B: Brick Wall C: Environment D: Shrek’s Castle E: Puss-n-boots Security Service F: Gingerbread Man’s Cookie Factory G: Roads H: 3 Blind Mice Delivery Service I: Dragon Power Service (DPS) J: Donkey Recycling F

23. Cell City Analogy: Kingdom of Far Far Away
In the kingdom of Far Far Away, the main export and production is a cookie service run by the infamous Gingy. Everyone in the town has something to do with making Gingy’s speciality giant cookies and the entire town is designed to build and export cookies effectively. The town Castle has the recipes for the special cookies, safely stowed for Gingy’s viewing. The town air is filled with sweet notes of ginger, brown sugar, and chocolate, which makes sitting on the green green grass even more enjoyable. Although Far Far Away is a happy little kingdom, the people have been ordered to stay within the town limits and cannot cross the border emphasized with a brick wall. The citizens are an important part of the town because they are needed to transport the cookies. They roll the giant cookies down the streets to various restaurants and grocery stores in town. The town’s men and women get their energy to roll the giant cookies from the never ending supply of pixie dust from the Pixie Dust Power Plant. Every part in the kingdom has a role and without everybody’s contribution to the cookie business, it would literally crumble into pieces.
