Subject: Plant transpiration with .01M of sugar water

All the twigs were presoaked in deionized water for a few hours. I came into 
lab and then soaked a select amount of twigs from my sample in a solution 
of .01M of sugar water for one hour. I then measured the transpiration rate of 
these twigs for five minutes. The tube that was connected to the plant and 
computer was full of normal tap water. I had a control group (twigs that were 
soaked only in water) and the experimental group (twigs that were soaked 
in .01M solution for one hour). Using the formula 
((0 minutes - 5 minutes)/SA of plant)x 100,000
I got a change in T units of 12.559 for my control group, and 18.576 for my 
experimental group. The slope (rate of transpiration) was greater for the 
experimental than it was for the control. There was a great difference for the 
experimental group than the control group. The pressure at the beginning was 
usually around .9861 for both experimental and control twigs, and ended for 
the control at .9331 in five minutes, and ended for the experimental at .9230
I am currious as to why there is a difference, what causes this difference? 
Why is the transpiration rate by .01M of sugar water different from the 
control.
