Aim to Investigate Water Relations in Two Plant Tissues

EVALUATION
In this experiment, there are several sources of error that have shown up on the graph. Theses are known as anomalies. Anomalies are points on a graph that do not follow the line of best fit. These could be caused by a difference in room temperature, human error, potato and swede not all being the same size, and many others. We try and keep errors to a minimum, by keeping variables the same apart from the one we are testing. If we can manage to keep variables the same, then there will not be as much error in the experiment. Any anomalies on my graph, have been highlighted and below are some possible causes of error.
The main problem of the experiment was the cutting of the tissues. This caused the most difficulty because of the precise measurements were required. We were required to cut the tissues at 0.5 cm by 0.5 cm by 7.0 cm. The equipment we were given did not cut either the potato or swede easily. This led to a huge inaccuracy between my vegetables. …
