What does an organism have more of…cells or organs? 1. An organelle is smaller than a cell. 2. An organ is bigger than a tissue. 3. An organ is made out of many tissues. 4. Examples of systems: skeletal, digestive, respiratory, nervous, reproductive, immune etc.. 5. An organism has more cells than organs. 22 L

22 We Do: Levels of Organization 1. 2. 3. 4. 5.
9/19/11 OQC Notes: Levels of Organization Standard 5a: Students know that plants and animals have levels of organization. (organellecelltissueorgansystemorganism) Objective: Students will compare the levels of organization in their body to the organization of their textbook. You Do: My body is organized! 1. 2. 3. 4. 5. 6. Vocabulary: Tissue = group of different cells Organ = group of different tissues Organ system = group of organs Organisms = group of systems 22L 22R

23 You Do : My body is organized! 
How does the organization of your body compare to that of your textbook? Use your notes on page 22R and your TABLE OF CONTENTS in the book to finish each sentence! Organism is like the whole book because… 2. Organ Systems are like the units in the book because… 3. Organs are like the chapters in the units because… 4. Tissues are like the sections in the chapters because…. 5. Cells are like the sentences in the sections because… 6. Organelles are like the words in the sentences because… 22L

24 Let’s play go around the room and share our ideas!!!

25 Notes: Levels of Organization
9/19/11 OQC Brainpop: Stem Cells 1. 2. 3. 4. Notes: Levels of Organization 22L continued 22R continued

26 Brainpop: Stem Cells How many different cells are in a human?
What does it mean to be a specialized cell? In what two ways are stem cells unique? How could stem cells be helpful to sick people? 22L continued

27 Where did these organs come from?
Brainpop: Stem Cells How many different kinds of cells are there in the human body? What does it mean to be a specialized cell? In what two ways are stem cells unique? How could stem cells be helpful to sick and injured people? 220 different kinds To have its own job! They are unspecialized and can differentiate into any cell! Where did these organs come from? Stem Cells!!!! Heart grown from stem cells! Trachea grown from stem cells!

28 Notes: Levels of Organization
9/19/11 OQC Brainpop: Stem Cells 1. 2. 3. 4. Notes: Levels of Organization Stem Cell Summary: 22L continued 22R continued

29 1. Mitosis = Stem cell divides and makes daughter cells
Stem Cell Summary: 1. Mitosis = Stem cell divides and makes daughter cells 2. Differentiation = daughter cells specialize into own structure and function

30 Cell differentiation lab from
Lets Finish the Cell differentiation lab from last week!!!

31 Mini-Lab: Cell Differentiation Demonstration
Step 1: Use a ball of clay to represent a single cell. Divide the “cell” into two equal smaller balls of clay, and then again into four. a. What is this process called when it is a real cell doing it? b. What are the new cells called? c. Compare and contrast these cells. How are they the same? How are they different? d. In the real human organism, these cells would NOT have differentiated yet. What would they be called? e. How are stem cells different from regular cells?

32 Structure (Draw what it looks like) Function (What is its job?)
Step 2: Now use each clay “stem” cell to show how differentiation works. In the table below, record what structure and function you decided to give each cell. Please explain why it needs to have this specific structure in order to complete its function. Structure (Draw what it looks like) Function (What is its job?) Why does it need to have this structure in order to complete its function? Cell #1 Cell #2 Cell #3 Cell #4 It has to be long to be able to reach out and touch other nerve cells To send messages

33 Conclusion PARAGRAPH:
All multicellular organisms start as one cell and end up as many different cells. For example, a human begins as one cell, and after 9 months of growth and development, ends up having trillions of different cells. EXPLAIN HOW THIS HAPPENS!!! Use the vocabulary words: mitosis, differentiation, and stem cells in your explanation. Give examples from your notes.

34 More Flashcards!!!!! Please get out your flashcards.

37 For students who have all their 28 flashcards finished, lets play review games with a friend!!!! 
Memory Pictionary Charades Quiz, Quiz, Trade (modified) For students who have not finished their flashcards, please silently work on them at your desk. If you lost the cards, please make more with your own paper. 

38  DNA model project is NOT due tomorrow!!!!!!!!!!!
So you can study for your EXAM, I changed the due date for the project to Thursday/Friday!!!!

39 Exam 1—review the 28 flashcards and notebook pp. 1-21
Unit 1: Cell Structure and Function 1a Students know cells function similarly in all living organisms. 1b Students know the characteristics that distinguish plant cells from animal cells, including chloroplasts and cell walls. 1c Students know the nucleus is the repository for genetic information in plant and animal cells. 1d Students know that mitochondria liberate energy for the work that cells do and that chloroplasts capture sunlight energy for photosynthesis. Unit 2: Cell Division and Specialization 1e Students know cells divide to increase their numbers through a process of mitosis, which results in two daughter cells with identical sets of chromosomes. 1f Students know that as multi-cellular organisms develop, their cells differentiate. 5a Students know plants and animals have levels of organization for structure and function, including cells, tissues, organs, organ systems, and the whole organism.
