1. The Cell!!!!
TB:pgs

2. 1- Seven Characteristics of Living Things
Breathing
Eating
Moving
Excreting
Reproducing
Growing
Reacts to the environment

3. 2-Examples Whales Ferns Breathing: O2 CO2 Eating: Krill Minerals
Moving: Swimming Cellular
Excreting: Urine, CO2 O2
Reproducing: Live Young Pollination
Growing: From 1m+ Spores
Reacts to the
environment: Fear Wilt
In conclusion they both meet the criteria and are therefore living

4. 2-Examples Car Breathing: O2 Eating: Gas Moving: Rolls Excreting: CO2
Reproducing: No
Growing: No
Reacts to the environment: Rusts
In conclusion, a car does not meet all the criteria, and therefore, is not living.

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

6. Cell
5-Cells do not have all the same size, shape, or function.

7. 6-There are Two Different Cell Types:
Animal Cells &
Plant Cells

8. Animal cell
7- Animal cells include: Cell membrane, cytoplasm, nucleus, vacuoles, endoplasmic reticulum, & mitochondrion.

9. 8 –Draw the Animal Cell

10. 9-Plant cell
5- Plant cells include: Cell membrane, cytoplasm, nucleus, vacuole, endoplasmic reticulum, mitochondrion, cell wall, chloroplast.

11. 10- Draw the Plant Cell

12. 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.

14. 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?

15. 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 yesterday?
How many can you relate to the parts of a city?

16. 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.

17. 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
E. Endoplasmic Reticulum
Roads or Highways
Transportation system
F. Mitochondria
Power Plant or solar panels or windmills
Provides power
G. Vacuole
Storage Facility – boxes, crates, and plastic bags
Stores food and waste
H. Chloroplast
Green grass within the city
Where photosynthesis takes place
I. Cell Wall
Brick wall surrounding city
Gives shape, structure, support, and protection

18. 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

19. 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

20. 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.

21. 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

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

23. 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

24. 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

25. Cells Class 2

26. 1- Exchanges Between the Cell and Its Environment
Diffusion
Osmosis
Photosynthesis
Cellular Respiration

27. Diffusion
2 – 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

28. Osmosis
4- Osmosis is the passage of water across a membrane that only allows certain substances to pass

29. Osmosis cont.
5-The solute is more concentrated on the left side to start with. This causes water molecules to move across the membrane toward the right until equilibrium is reached.
6-Selectively Permeable Membranes allow some things across the membrane. For example water and oxygen move freely across the cell's membrane, by diffusion

30. Photosynthesis
7-Solar energy + water + carbon dioxide  Oxygen + glucose
Draw

31. Cellular Respiration
8- Oxygen+ glucose  Carbon dioxide+ water + energy.
