Difference

Many differences presented in these figures can be explained by the weather. The original figure that was created, was taken after a rainshower had fallen on UMass. The rain would account for the dark color on the trunk of the tree that appears in Figure 1 and not in Figure 2. The panels in Figure 2 were created after a snowfall, the snowfall is the reason why the ground is white and why there is a white dusting on the trunk of the trees.

The differences in the labeling would be due to the way the information was presented. There was no mention of capitalization in the methods, just that the labels used were a, b, and c. This would have led to some confusion in the replicators end and a creation of panels with a lowercase labeling. The reason for no white square behind the letters may have been due to more confusion from the replicators end.
