Photosynthesis and Cell Respiration Review Lookabaugh Day 6 Review PLAY STUMP the CLASS! Students create their own questions to stump classmates.

Photosynthesis What is it? A cell process that converts light energy into chemical energy (glucose) Who uses it? Plants only Location – Chloroplast Purpose - Make glucose that can be used in cellular respiration Gas Produced - Oxygen Equation – 6CO 2 + 6H 2 O + sunlight  C 6 H 12 O 6 + 6O 2

Cellular Respiration What is it? A cell process that converts chemical energy (glucose) into ATP Who uses it? Plants and Animals Location – Mitochondria Purpose – Make ATP to use in daily cell functions Gas Produced – Carbon Dioxide Equation – C 6 H 12 O 6 + 6O 2  6CO 2 +6H 2 O + ATP

ATP ATP- energy used in the cell; energy is release when the bond between phosphate groups is broken Energy is stored between the second and third phosphates Adenosine Triphosphate

Bromothymol Blue (BTB) indicates for the presence of CO 2 BTB turns yellow in the presence of CO 2 BTB stays blue in the presence of O 2 BTB will turn green if there is both CO 2 & O 2

13 5. A scientist wants to measure how much gas is released by a plant to estimate how fast it is photosynthesizing. Which measurement should the scientist take? A meters of carbon dioxide B milliliters of oxygen C grams of carbon dioxide D centimeters of oxygen

14 A horticulturist hypothesized that if he increases the level of carbon dioxide (CO 2 ) in the air of his greenhouses, then his plants will absorb carbon more quickly. He collected the following data from an experiment performed on is plants. Which statement is true about the data in the table? A.The data supports the hypothesis because the plants grew more when the level of CO 2 increased. B.The data supports the hypothesis because the plants grew less when the level of CO 2 increased. C.The data contradicts the hypothesis because plants grew less when the level of CO 2 increased. D.The data contradicts the hypothesis because the plants grew more when the level of CO 2 increased. 6

Elodea, a freshwater plant, releases gas bubbles when it is placed in direct light. In an investigation, a student placed a lamp at different distances from an aquarium containing Elodea. The student counted the number of bubbles produced by the Elodea plant. His data are shown in the table below. The bubbles released by Elodea contain mostly A.Oxygen B.Carbon dioxide C.Nitrogen D.Water vapor
