Cellular Respiration

Cellular Respiration Lab Cedric Olinger Hr. 3 Question/ decide: Will temperature profess the rate of respiration on germinated plants? supposition: If temperature is different, then the atomic number 8 level in the chamber will gradually gain because the plant has move all the available carbon dioxide into type O in the chamber. Controls and Variables: Independent Variable: temperature Dependent Variable: oxygen case Control Group: Non-Germinated Peas Controlled Variables: Sunlight, Number of pea plants, water, environment Experimental Variables: Temperature Materials utilize: 20 Green Peas (Non-Germinated) 20 Green Peas (Germinated) Oxygen shove along sensor tripe Cubes Thermometer 100 milliliter beakers Petri Dish number: 1.Collect the required materials as shown above from the teacher with your lab partner. 2.Put your 20 Germinated peas in a container. 3.Get a Bowl of cold icing the puck the puck water, and a bowl of hot wa ter for the pea container ready. 4.In your pea container, insert your oxygen gas sensor and elicit the container within the cold water, and then the hot water. Record your data in each hot and cold water for a minimum of 120 seconds, or more. 5.Repeat the steps #2-4 with the non-germinated peas, and demo your results. 6.Return to desk and appear further instructions.
