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

Objectives Explain how materials move through simple diffusion. (SPI 0707.1.5) Compare the chemical compounds that make up the reactants and products of photosynthesis and cellular respiration. (SPI 0707.3.1) Interpret a diagram to explain how oxygen and carbon dioxide are exchanged between living things and the environment. (SPI 0707.3.2) 2

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

EQUATION FOR PHOTOSYNTHESIS 4

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. ² ² 5 5

The Connection Between Photosynthesis and Respiration 6 6

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

EQUATION FOR RESPIRATION 8

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

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.
