Cellular Respiration Lab Report

A detailed Summary of Cellular Respiration Lab Report

This lab was done to determine the relationship of gas production to respiration rate. Justin Pyka and I did the lab on December 12th, 2000 in Mr. Myers' room. The lab was done with dormant pea seeds and germinating pea seeds. It was done to test the effect of temperature on the rate of cellular respiration in ungerminated versus germinating seeds. We had to determine the change in gas volume in respirometers. This was done to determine how much oxygen was consumed during the experiment. The respirometers contained either germinating, or non-germinating pea seeds. I think that the germinating seeds will have a higher oxygen consumption rate in a room temperature water bath than the non-germinating seeds. My reason for this hypothesis is that a dormant seed would not have to go through respiration because it is not a plant yet. A germi

This lab was a good representation of what effects temperature has on cellular processes because it showed that respiration slowed down when the temperature was reduced, and respiration increased when the temperature increased.

See lab handout for methods of completing the experiment and recording the results.

I think that my hypothesis was correct because my results from the experiment show that the vials containing the germinating seeds consumed more oxygen in the room temperature water bath than the other vials.

nating seed would consume more oxygen because it is growing, and therefore would need to consume oxygen by going through the process of!

After completing this experiment, I have come to the conclusion that a germinating seed of a plant consumes more oxygen than a dry seed of a plant. When the germinating seed is cooled down however,
