1. Bell Work: 4/9/18
Have your study guide out and be ready to review diffusion and photosynthesis and respiration.

2. I can explain how particles move during the process of diffusion.
I can identify the reactants and products of photosynthesis and cellular respiration.
I can explain how oxygen and carbon dioxide travel through a cycle between chloroplasts and mitochodria. 

3. Diffusion
SPI Explain how materials move through simple diffusion.
Diffusion

4. A raw egg without a shell is placed in a highly concentrated sugar solution. What will happen to the egg?
(Hint: forget about the sugar!)
Draw out the question

5. A blood cell is placed into a solution that has a high concentration of salt. What will happen to the cell?
Draw the question

6. Study Guide KP!: 1.5 Diffusion
Diffusion: movement of particles from high  low concentration (ratios)
Osmosis: movement of water across a semipermeable membrane
Membrane allows some things through (like water), but not all (like glucose/starch)

7. Photosynthesis & Cellular Respiration
ATP
Photosynthesis & Cellular Respiration
SPI
Compare the chemical compounds that make up the reactants and products of photosynthesis and respiration.
SPI
Interpret a diagram to explain how oxygen and carbon dioxide are exchanged between living things and the environment.
Photosynthesis
Cellular Respiration

8. Study Guide KP!: 3.1 Photosynthesis & Respiration
Photosynthesis: 6H2O (water) + 6CO2 (carbon dioxide) + light energy  6O2 (oxygen) + C6H12O6 (glucose)
Cellular Respiration: 6O2 (oxygen) + C6H12O6 (glucose)  6H2O (water) + 6CO2 (carbon dioxide) + ATP (energy) * The arrow points to the products!

9. Most single-celled aquatic organisms use oxygen that is dissolved in water. When the dissolved oxygen concentration in the water is greater than the oxygen concentration in the organism, oxygen molecules pass through the cell membrane into the organism. What process causes this movement of oxygen molecules? 
  a.respiration             b.photosynthesis
  c.mitosis                   d.diffusion

10. The diagrams below show concentrations of particles inside and outside a cell. In which situation would particles move OUT of the cell through diffusion?

11. A student put a stalk of wilted celery into a glass of water
A student put a stalk of wilted celery into a glass of water. After one hour, the celery was no longer wilted. Which sentence best explains why the celery stalk was no longer wilted? a. Salt diffused out of the cells of the celery stalk. b. Salt diffused into the cells of the celery stalk. c. Water diffused out of the cells of the celery stalk. d. Water diffused into the cells of the celery stalk.

12. After a living cell is placed in pure water, the cell will
a.enlarge when water diffuses across the membrane into the cytoplasm.
b.shrink when large molecules are transported into the cytoplasm.
c.enlarge when water from inside the cell is carried out across the membrane.
d.shrink when sugars diffuse out of the cell across the membrane.

13. The diagram below shows a process that occurs in living organisms

B   Glucose is a product of both photosynthesis and cellular respiration. 
C   Water is a reactant of both photosynthesis and cellular respiration. 
D   Products in photosynthesis are reactants in cellular respiration.  

15. Some organisms in an environment are shown in the picture below

16. Which of the following chemical compounds is a product of photosynthesis and a reactant of respiration? A sucrose B water C oxygen D glucose

18. During respiration, glucose (C6H12O6) and oxygen (O2) react together and they produce:
A oxygen (O2) and carbon (C). B glucose (C6H12O6) and methane (CH4). C carbon dioxide (CO2) and water (H2O). D hydrogen (H2) and oxygen (O2). 

19. A student sets up an experiment in which she wants to measure the amount of oxygen produced by two plants. If she puts one plant in the dark and one plant in the light, what will happen? A The plant in the light will produce oxygen while the plant in the dark will not. B The plant in the dark will produce oxygen while the plant in t he light will not. C Both plants will produce an equal amount of oxygen. D Neither plant will produce oxygen.
