Cellular respiration pea lab answers

    • What is the purpose of the cellular respiration pea lab?

      The purpose of this lab is to calculate the rate of cell respiration in germinating and non-germinating peas. If we measure the rate of respiration between germinating and non-germinating pea plants, then the germinating pea plant will have a faster rate of respiration than the non-germinating peas and beads.

    • What is the purpose of a U-tube manometer in a cellular respiration pea lab?

      The oxygen uptake is detected by manometry. Typically, a U-tube manometer is used, which directly shows the pressure difference between the container and the atmosphere. As an organism takes up O 2, it generates a proportionate quantity of CO 2 (see respiratory quotient), but all the CO 2 is absorbed by the soda lime.

    • How do you measure the rate of cellular respiration in pea plants?

      The data measured the rate of respiration of peas in each respirometer. This was done by submerging the respirometers in water and observing the the volume of oxygen left in each. The less oxygen contained in each respirometer, the more that was consumed through respiration.

      Use the linear regression function to determine the respiration rate, which is the slope of the line, m. Record the respiration rate in ppm CO 2 s-1. PROCEDURE 1 QUESTIONS 1. Use the respiration rate determined in Step 5, in CO 2 ppm/s, and the mass of your peas determined in Step 3, in grams, to determine the normalized respiration rate per ...
