Results after friday 13 lab test

Results

.....Temperature ..... ..... Oxygen Content .....
Cold Water [-150c] ..... ..... ...7.94 mg/L
Warm Water [400c] ..... ..... ..6.98 mg/L
Mean Water [370c] ..... ..... ..8.18 mg/L

Our Point of View:

An optimum temperature ranging from 25oC to 35oC is a good temperature range for the highest rate for photosynthesis.

At temperatures around 0 degrees the enzymes stop working as they are inactive and at very high temperatures the enzymes are denatured. Since both the stages of photosynthesis require enzyme activity, the temperature has an effect on the rate of photosynthesis.

Thoughts:

I think that the range temperatures we measured could be more chosen with
more reason instead of randomly picked in a given range. I would have also liked to have made more measurements to find the optimum temperature of the plant.

Due to time constraint and everyone mistaking the pH sensor for the oxygen sensor, there was very little time left to conduct the experiment. Each set-up had a ‘photosynthesis’ time of only 3 minutes which is really short.

We using the oxygen sensor were more reliable than counting bubbles but there were still inaccuracies in the experiment.
