JQ: What can the appearance of the animal and plant cells below tell you about their functional differences? Explain. (Anatomy & Physiology) Human Cheek Cells 400x Elodea plant Cells 400x
Tissues = group of similar cells working together.
Lines and protects body surfaces. Example: Skin & Lining of Organs Connects, supports and insulates body. Example: Blood, fat, bone.
Contracts & relaxes to produce movement. Example: walls of intestines, heart Carries info. to all parts of the body. Example: neurons
Multipolar Neuron Smear
Amoeba Stentor Paramecium Euglena Volvox Each picture has a link to a video
JQ: What does it mean to be independent? Are you independent? Explain.
Humans are made up of trillion's of cells that have special jobs in order to work together. This way they have a better chance of surviving. Our cells can’t survive independently
What is a cell? The basic unit of structure and function for all living things!
A theory is a well tested hypothesis that has not been proven incorrect to date. What is a theory?
1.All living things are made from one or more cells. 2.Cells are the basic unit of structure and function in living things. (Smallest form of life!) 3.New cells come from existing cells. What is cell theory? Theodore Schwann Matthias Schleiden
1.Prokaryotic Cell – cells that lack a membrane bound nucleus. Example: Bacteria and archaea What types of cells exist? 2. Eukaryotic Cell – a cell that contains a membrane bound nucleus & many specialized structures called organelles.
“Tiny organs” - specialized structures found within a cell. What are organelles?
Single Celled – 1 cell (ex. Ameoba, Paramecium) Multicellular –many specialized cells working together (plants and animals) Types of Eukaryotic cells
JQ: What makes an Avatar’s skin blue? Explain.
JQ: Would you rather have the ability to shrink to the size of a pin head or grow to the size of an oak tree? Explain. *You need your textbook today*

Tissue practice quiz
Go to macromolecules PPT Link to Power point You are what you eat…literally Your cells are made of four main types of large molecules: Carbohydrates, Lipids, Proteins, and Nucleic Acids. They can only do their job if they have the right amount of each of these.
Internal Stomach Lining Tissue
Cross Section Small Intestines
Internal Lining of Gallbladder
Cilia of the Trachea

JQ: When scientists first attempted to make an avatar they were unsuccessful. After further inspection they realized that a virus snuck past its immune system and into its cells. Once in the cell it took over and destroyed the cells. Scientists think that the avatar’s cells were missing an organelle. Which organelle was most likely missing from the avatar’s cells?

JQ: What could he grow up to be? Explain.
Start as one cell with unlimited potential! End with trillions of specialized cells each cell being limited potential!
Stem Cells: Cells that haven’t turned into a specific cell type yet (they’re undifferentiated)
Differentiation: Process that turns an unspecialized cell into a cell with a specific job.
What are stem cells? What does it mean to differentiate? What are the different types of stem cells? What is the goal of stem cell research? Link to GSLC
What are the issues?
2. Stem Cell Debate Video
You’ve learn about how organisms interact on this planet, and the damage that humans are causing to the balance of life. We’ve even discussed some solutions to the problem. You’ve also learned about how organisms are put together, from cells to organ systems.
Would you choose to be cryogenically preserved if the technology was available? Explain.
JQ: If you are going to build an Avatar you will need to gather some DNA from a Na’vi and a human. Getting the DNA from a human is easy, but how would you go about getting it from a Na’vi? Explain.
Where do we find DNA?
With something so small how is it possible to pull it out and look at it? Extraction Lab Practicing your extraction technique
How come you don’t start to become a strawberry when you eat strawberry DNA?
