For AP Biology Classes

• Features microrespirometers
• Time required: ~120 minutes

In this experiment, students learn how to apply the gas laws to the function of the microrespirometer. Students will observe cell respiration of germinating seeds and describe the effects of temperature on the rate of cell respiration.
