1. Focus Lesson: Buzz Words
Remember our procedures! Come in and quietly get your focus lesson and pencil box. Begin working immediately!
Complete the Taking it to the Next Level Column!
Amylase vs Amylose
*Have you completed every column?
Were you absent? Don’t forget to check the calendar!

2. By the end of class, I will be able to…
Identify the three principles of the cell theory.
Describe how continuous investigations and/or new scientific information influenced the development of cell theory.
Identify the structure and function of cell organelles.

4. Review: Disproving Spontaneous Generation
Page 50 What is spontaneous generation? Why isn’t it true? What kinds of experiments did your group develop to disprove this once widely accepted theory?

5. The Cell Theory

6. Page 51: Cell Theory Graphic Organizer
To save time you will be copying notes on a handout. This will also help organize your notes in a timeline.

7. Theory attempts to explain an observation using support

8. The Cell Theory History
Robert Hooke
Discovers the cell (1665)
" little boxes or cells distinct from one another."
Check out that OLD microscope!

9. The Cell Theory History
Francisco Redi
makes first attempt at disproving “spontaneous generation” (1668)

10. The Cell Theory History
Anton van Leeuwenhoek
discovers “animalcules” (single- celled organisms) swimming in a drop of pond water (1674)
Stronger microscope than Hooke in 1665

11. The Cell Theory History
Matthias Schleiden
proposes that plants are made of cells (1838)
Original drawing of plant cells by Schleiden.

12. The Cell Theory History
Theodor Schwann
Studied animal cells
After comparing observations with Schleiden, concludes that all living things are made of cells and that these cells form spontaneously by free-cell formation (1839)
Original drawings of plant and animal cells

13. The Cell Theory History
Rudolf Virchow
after studying cell division, reports that all cells come from pre-existing cells (1855)

14. The Cell Theory Establishes the following three principles:
All organisms are made of cells.
All existing cells are produced by other living cells.
The cell is the most basic unit of life.
Developed after a span of 200+ years of many scientists studying cells

15. Cell Theory Recap
After years of studying, the scientific community made the following conclusions...

16. All organisms are made of cells.

17. All existing cells are produced by other living cells.

18. The cell is the most basic unit of life.
Characteristics of Life
Cells
Homeostasis
Adapt (EVOLVE)
Respond to their Environment
Grow and Develop
Energy and Materials
Reproduce
DNA

19. Cell Structure
The development of technology, like the microscope not only allowed scientists to develop the cell theory, but also gave scientists a way to classify cells based on their structure.

20. On Page 52 Create TWO T Charts on your page
There are two forms of classification you MUST know to be successful in this class
Prokaryotic v Eukaryotic Plants v Animals

21. Prokaryotic vs. Eukaryotic
Decode the Vocabulary
Prokaryotic vs. Eukaryotic
“Karyose” is a Greek word meaning kernel, or seed, like the pit of a peach.
The “kernel” of the cell is the nucleus.
“Pro” means before
“Eu” means true
Prokaryotic = before nucleus
Eukaryotic= true nucleus

22. Visual Comparison

23. We can classify it as PLANT or ANIMAL
If a cell is EUKARYOTIC
We can classify it as PLANT or ANIMAL

24. Plant v Animal Activate your prior knowledge!
What differences can you spot between plants and animals?
What similarities must the share if they are both living?
Complete the second Venn Diagram with your table group.

25. Organelles: TINY ORGANS
Plants and animals do different things (have different functions), therefore they are built differently.
Every cell has tiny little “organs” or organelles that allow them to work.
You must memorize the structure and function of these organelles.
You also need to know what kinds of cells they are present in:
Prokaryotic v Eukaryotic
Plant v Animal

26. DO NOT COMPLETE THE LAST COLUMN (SCHOOL ANALOGY)
Organelles
Textbook Pages
73-79
Use this handout to complete the graphic organizer, which we will staple onto page 53 later, with your group.
If it does not clearly state that the structure is only found in one type of cell, you should assume it is in both Plant and Animal
REMEMBER!
Structure= How is it built??
Function= What does it do??
DO NOT COMPLETE THE LAST COLUMN (SCHOOL ANALOGY)

27. Home Learning
Next class you will have Quiz 7, which will cover both Cell Theory AND Organelles. YOU SHOULD GET READY FOR IT!
Complete the Graphic Organizer on Page 53 using this information provided in the textbook.
Create flashcards using Page 53 and STUDY!
This is pure memorization. You have to memorize their structure and function.
