1. Test Review - Cells (Part 2): 1.Photosynthesis 2.Respiration 3.Specialized Cells 4.Levels of Organization

2. Quick Check Photosynthesis 1.Write the chemical reaction for Photosynthesis.(show what goes in AND what comes out) Respiration. 2.Write the chemical reaction for Respiration. (show what goes in AND what comes out)

3. Chemical Equation for Photosynthesis carbon dioxide + water +  glucose + oxygen Photo = light Synthesis = combining parts to make something Photosynthesis = combining water and carbon dioxide (with the help of the sun) to make sugar! REACTANTSPRODUCTS

4. Chemical Equation for Respiration oxygen + glucose  carbon dioxide + water + ENERGY (ATP) Respiration = the process of breaking down glucose (in the presence of oxygen) to make ATP ENERGY! REACTANTS PRODUCTS

5. Quick Check “All cells look and function the same.” Explain (with EVIDENCE) why you agree or disagree with the statement. I agree/disagree because…

6. What kind of cell is it? a red blood cell What is its function/job? to carry oxygen around the body Why do you think it looks the way it does? (How does it’s shape relate to it’s job?)

7. What kind of cell is it? a nerve cell What is its function/job? to send signals/impulses around the body Why do you think it looks the way it does? (How does it’s shape relate to it’s job?)

8. What kind of cell is it? a skin cell What is its function/job? the skin serves as protection for the internal organs/structures Why do you think it looks the way it does? (How does it’s shape relate to it’s job?)

9. Definition: a living thing that carries out life processes ORGANISM ORGAN SYSTEMS ORGAN TISSUES Definition: similar tissues working together with a common purpose Definition: similar cells working together with a common purpose Definition: smallest unit of life Definition: a group of organs working together to perform body functions Picture: CELLS

10. Study Questions 1.What is the main purpose of photosynthesis? 2.What type of cells do photosynthesis? 3.Where in the cell does photosynthesis happen? 4.What is the main purpose of respiration? 5.What type of cells do respiration? 6.Where in the cell does respiration take place? 7.**What is the relationship between photosynthesis and respiration? 8.Why are cells specialized? (Why don’t all cells look the same?) 9.Name a type of specialized cell and explain what it does. 10.Put the following terms in order from simple to complex: Tissues, Organism, Organ Systems, Cells, Organs

11. Review Summary: Copy the table below. Answer each of the questions using your notes and textbooks. QuestionAnswer Why don’t all cells look alike? How are these terms connected  tissues, cells, organism, organ systems, organs ? Show and explain the relationship/connection between photosynthesis and respiration.
