1. CELLS
Cell Structure

2. 1/6/15 Cells Key Question: How are cells structured and organized?
Initial Thoughts:

3. Bill Nye Movie
Evidence #1: Bill Nye Movie Cells - Bill Nye Cells

4. Evidence #2: Notes & Diagrams
Take notes from the PowerPoint.

5. Cell Theory Cells are the basic unit of life
All living things are made of cells
Cells come from other cells

6. Cells are… Definition: The basic unit of life
Cells produce tissues  Tissues produce organs  Organs produce organ systems  Organs systems produce organisms

7. Single Cells do everything by themselves;
What is the difference between a single cell and cells working together?
Cell Specialization by Brainpop
Single Cells do everything by themselves;
Cells in tissues and organs divide up the work!

8. The discovery of cells
Robert Hooke discovered the first cells. Cork Cells were thought to have been these cells.

9. Anton von Leeuwenhoek was first to observe one celled living things
Anton von Leeuwenhoek was first to observe one celled living things. Examples of these were bacteria and parameciums.

10. Prokaryotic vs. Eukaryotic
Prokaryotic Cells: NO NUCLEUS
Example: Bacteria
Eukaryotic Cells: Have a TRUE NUCLEUS
Example: all cells in your body

12. Create 2 columns:
Cell Part Function

13. CELL PART:

FUNCTION:
Gel-like material inside cells
Holds organelles

Directs all cell activities
CELL PART:
NUCLEUS
With the electron microscope

16. Helps to make ribosomes;
FUNCTION:
Helps to make ribosomes;
Found inside nucleus
CELL PART:

17. Pathway for moving materials through cell
FUNCTION:
Pathway for moving materials through cell
(the “express-way”)
CELL PART:
Endoplasmic
Reticulum or ER

18. FUNCTION: CELL PART: Make protein! RIBOSOMES
Under the electron microscope:
A simple diagram
Under the electron microscope:

19. Releases energy in the cell; the “powerhouse”
FUNCTION:
Releases energy in the cell; the “powerhouse”
CELL PART:
MITOCHONDRIA
Under the electron microscope:

20. FUNCTION:
Contains genes or instructions for cell’s activities (found in nucleus)
CELL PART:
CHROMATIN (DNA)
Under the electron microscope:

21. Converts sunlight into cell energy
FUNCTION:
Converts sunlight into cell energy
(Found in plants ONLY!)
CELL PART:
CHLOROPLAST
Under the microscope

22. The outer structure in plant cells; made of cellulose
FUNCTION:
The outer structure in plant cells; made of cellulose
CELL PART:
CELL WALL
Under the microscope

23. Store water, food, and waste products;
FUNCTION:
Store water, food, and waste products;
Very large in plant cells, small in animal cells
CELL PART:
VACUOLES
Under the microscope

24. Nicknamed “UPS”—Packages & secrete substances made inside the cell
FUNCTION:
Nicknamed “UPS”—Packages & secrete substances made inside the cell
CELL PART:
GOLGI BODIES
Under the microscope

25. FUNCTION: CELL PART: Digests cell wastes LYSOSOMES “garbage disposal”
Under the microscope

26. Help direct cell division during mitosis; only in animal cells
FUNCTION:
Help direct cell division during mitosis; only in animal cells
CELL PART:
Centriole

27. What are the two parts that plant cells have that animal cells do not have?
Cell Walls
Chloroplasts

28. Draw an animal and plant cell
Using this powerpoint and the Cell Games Link on Swift, draw and label an animal and plant cell.
Cell Games:

29. Animal Cell

30. Plant Cell

35. Analysis Questions
What are the differences between a eukaryotic cell and a prokaryotic cell? Give examples of organisms of each.
What is the job of the cell membrane? Why would this be important to a cell?
Compare and contrast plant cells and animal cells. (How are they different? How are they the same?)

36. Summary Make sure this is thoughtful and thorough.
In a well developed paragraph:
What did you think before about how cells are structured? (look back at your initial thoughts)
What did you learn about how cells are structured? Be specific! (look back at your evidence section).
What evidence do you have that you learned this?
Further Thoughts
Make sure this is thoughtful and thorough.

37. Reflection
Draw a picture of how cells are organized to make complex organisms.
Cells tissues  organs  organ systems  organisms

38. Big Idea: Cells Cells are the building blocks of life
Cells tissues  organs  organ systems  organisms
Organelles each have a different job
Prokaryotic cells don’t have a nucleus; Eukaryotic cells do.
