Transcript of Cell Respiration Lab

Cell Respiration Lab Purpose: study the effect of temperature on cellular respiration by using an oxygen gas sensor to measure the oxygen levels (CR uses up oxygen) Materials used:
25 germinating beans
25 non-germinating beans
Oxygen gas sensor Temperatures tested: room temperature & cool temperature
(22 degrees Celsius & 1 degree Celsius) Results for rate of Respiration (%/min):
Germinating, room temp: -.03204
Non-germinating, room temp: -.01478
Germinating, cool temp: .009616
Non-germinating, cool temp: -.008613 What this means:
