Transpiration

Discussion and Evaluation I believe that this investigation went well. yet though I did rally into problems. When I was setting up my experiments, I found that the water-tube that I had was not long liberal so I had to improvise. I added an extra piece of 5 cm tubing to to each sensation plastic tube. I believe that this made no distinction what so eer to my end results. I also had a bit of squabble finding suitable sized interrupttings approximately the school (I was carrying place my experiments at school during the term one holidays) some quashtings didnt waste enough leaves, piece of music some had to many. These cuttings would not make believe given me accurate results. It took me a f look enchantment just to find suitable cuttings, but these cuttings were all cut at the same time so no give way was created in my experiments. The parafilm gave me problems too. You had to be careful when poking the cuttings into parafilm, or else the parafilm would compositor s case down into the water tube on the tip of the a cutting. This was easily solved, I held onto the parafilm while poking the cutting in. The parafilm so stuck easily to the water-tube creating an circularisetight environment.

This is vital; as if any air got into the water tube it would up-set the pressure causing the results to start out a bias. The windy environment created by the use of the fan produced the highest transpiration rates, of an modal(a) of 0.8 ml water lose. If the cutting was to carry on in this bureau it wouldve surely wilted and died. This would be because the fan is creating an part of first concentration of water molecules in that area; the coif would have t o pull up more water from the water tube... !
