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!Slide2
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
.Slide3
How will we get there?

The Cell Theory History
Robert HookeDiscovers the cell (1665)" little boxes or cells distinct from one another."
Check out that OLD microscope!Slide9
The Cell Theory History
Francisco Redi makes first attempt at disproving “spontaneous generation” (1668) Slide10
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 1665Slide11
The Cell Theory History
Matthias Schleiden proposes that plants are made of cells (1838)Slide12
The Cell Theory History
Theodor SchwannStudied animal cellsAfter comparing observations with Schleiden, concludes that all living things are made of cells and that these cells form spontaneously by free-cell formation (1839)Slide13
The Cell Theory History
Rudolf Virchowafter studying cell division, reports that all cells come from pre-existing cells (1855) Slide14
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
cellsSlide15
Cell Theory Recap
After years of studying, the scientific community made the following conclusions...Slide16
All organisms are made of cells.Slide17
All existing cells are produced by other living cells.Slide18
The cell is the most basic unit of life.

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.Slide20
On Page 52
Create TWO T Charts on your pageThere are two forms of classification you MUST know to be successful in this class
Prokaryotic v Eukaryotic
Plants
v Animals
Slide21
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 nucleusSlide22
Visual ComparisonSlide23
If a cell is EUKARYOTIC
We can classify it as PLANT or ANIMALSlide24
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.Slide25
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 EukaryoticPlant v AnimalSlide26
Organelles
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 AnimalREMEMBER!Structure= How is it built??
Function= What does it do

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

and STUDY!
This is pure memorization. You have to memorize their
structure and function.
