Cellular Respiration (Adapted from: State Adopted Prentice Hall Laboratory Manual B) – NGSSS: Explain the interrelated nature of photosynthesis and cellular respiration. (AA) SC.912.L.18.9 SC.912.L.14.7 Relate the structure of the major plant organs and tissues to physiological processes. (AA) Purpose of Lab/Activity: To understand how photosynthesis and cellular respiration work hand-in-hand. To observe how cellular respiration occurs under aerobic conditions. Prerequisites: Prior to doing this lab, students should have been taught about cellular respiration including lactic acid fermentation, alcoholic fermentation, glycolysis, the Krebs cycle, and the electron transport chain. Students should also be aware of how photosynthesis and cellular respiration go hand-in-hand. The products of one process are the reactions of the other and vice versa. Materials (per group): Distilled water Purple cabbage leaves or Bromothymol blue Straw Test tube rack Heat-resistant gloves Slotted spoon (large) Hot Plate Stoppers Cotton ball Radish seedlings (10) Beakers 500-mL (two) Forceps Test tubes (4) Aluminum foil Procedure: Day of Activity: What the teacher will do: Prep work: Germinate radish seedlings at least one week before lab. Use 1 part Bromothymol blue to 10 parts of water as a substitution of the cabbage indicator. Essential question (or problem statement): do organisms release “How energy from food?” Procedures: Students should read the entire investigation. Then, work with a partner to answer the questions. These questions should “engagement” Before be in the hand-out. student’s activity: Once the students have completed the questions, initiate a class discussion asking different students to share their answers. Continue the discussion by asking the following questions. What is cellular respiration? How are the processes of photosynthesis and cellular respiration related? What are the reactants and products of cellular respiration? In this investigation, how are we going to find out if plants carry on cellular respiration?
