1. Bell Work: 1/16/14 Write the question and answer.
Where does photosynthesis take place? Be specific!
Work on study guide: #1-18

2. Objectives
Explain how materials move through simple diffusion. (SPI )
Compare the chemical compounds that make up the reactants and products of photosynthesis and cellular respiration. (SPI )
Interpret a diagram to explain how oxygen and carbon dioxide are exchanged between living things and the environment. (SPI ) 2

3. Reactants vs. Products
Reactants are what you need to make something- The reactants for photosynthesis are Sunlight, Carbon Dioxide and Water.
Products are what you make- The products for photosynthesis are Glucose (sugar) and Oxygen. 3

4. EQUATION FOR PHOTOSYNTHESIS4

5. Photosynthesis and Cellular Respiration
Cellular respiration is a chemical reaction that occurs in cells.
During cellular respiration, cells use oxygen to produce energy from food.
Food (glucose) is broken down into CO and H O, and energy is released.
The released energy is used to maintain body temperature in animals. It is also used to form ATP, which supplies energy that fuels cell activities. 5 5

6. The Connection Between Photosynthesis and Respiration6 6

7. Reactants vs. Products
Reactants are what you need to make something- The reactants for cellular respiration are Glucose (sugar) and Oxygen.
Products are what you make- The products for cellular respiration are Carbon Dioxide, Water and ATP. 7

8. EQUATION FOR RESPIRATION8

9. Alternative to Cellular Respiration
Fermentation produces ATP without using oxygen. It can occur in muscles when they are unable to get oxygen for respiration.
Fermentation also produces lactic acid. This acid can cause muscle fatigue. 9

13. Meatloaf
6 ounces garlic-flavored croutons
1/2 teaspoon ground black pepper
1/2 teaspoon cayenne pepper
1 teaspoon chili powder
1 teaspoon dried thyme
1/2 onion, roughly chopped
1 carrot, peeled and broken
3 whole cloves garlic
1/2 red bell pepper
18 ounces ground chuck
18 ounces ground sirloin
1 1/2 teaspoon kosher salt
1 egg

14. Recipe Cards: Reactants, products, & process
Photosynthesis: Glucose & Oxygen
6CO2 Carbon Dioxide
6 H2O Water
Sunlight
Combine the carbon dioxide and water and heat with sunlight in the chloroplast to produce glucose and oxygen.

15. Recipe Cards: Reactants, products, & process
Cellular Respiration: ATP, Carbon Dioxide, and Water
C6H12O6 Glucose
6O2 Oxygen
Combine glucose and oxygen in the mitochondrion to produce ATP, carbon dioxide, and water.

16. How Animals Obtain Oxygen
Gills- organs that remove oxygen from water and send it to the blood; also remove CO2 from the blood. (Fish)
Swim bladder- oxygen and gas filled organ that allows fish to stay afloat.
Lungs- sac-like organ that removes oxygen from the air and puts in the bloodstream. (humans, amphibians, reptiles, birds)
Air Sac- special organ attached to lungs in a bird and allow the bird to fly.
Skin- Animals like amphibians can absorb oxygen through their skin. The oxygen goes directly into their blood vessels. Amphibians skin is usually very thin and full of vessels. They are able to lose water easily and that why they usually live in water.
