14 28.1: Levels of Organization Key Concept: The human body has five levels of organization Overview There are more than 200 different types of human cells 14'

15 Overview We only started out as ONE cell Overview How did one cell become many different types of cells?? 15'

16 Overview Our cells start out as stem cells, which multiplied! Steps in Cell Specialization 16'

17 1. Stem Cells can become any of 200 types of cells in the human body Initially, a stem cell does not know what type of cell it will become It has the potential to become many different types of cells 17'

18 2. Determination = Stem cell commits to becoming a specific type of cell I ve decided to go to medical school 3. Example: Muscle cell 18'

19 4. Differentiation = Committed cells develop specialized structures and functions I m a resident at a hospital now, & have received training to become a doctor 5. Examples: Cardiac, skeletal, and smooth muscle cells 19'

20 Five Levels of Organization 6. Cell Definition: Smallest form of life 20'

21 7. Tissue Definition: Groups of similar cells that work together to perform a function 8. Organ Definition: Different types of tissues functioning together 21'

22 9. Organ System Definition: Two or more organs working in a coordinated way 10. Organism Definition: Collection of organ systems working together 22'

23 Pair-Share-Respond 1. What is a stem cell? 2. Distinguish between determination and differentiation. 3. What are the five levels of organization, from largest to smallest? 4. Provide an example of each of the five levels of organization Study Guide CW 2. Catch up on stamps 3. Quiz corrections or alternative assessment due Monday 4. Quiz on 28.1 Monday 23'
