3. Results

3.1 Results for the number of colonies for each plate 

The first table and graph are the results for the number of colonies found on each plate of agar in the two sets. The data were tabulated and then presented in a graph as shown in figures 1.6 and 1.7.

3.2 Results for percentage of yeast killed by sunlight

The table and graph in figures 1.8 and 1.9 shows the number of colonies found on the exposed plates divided by the number colonies found on control plates for each type of dilution.

3.3 Observations 

With reference to the graph and table above, it is clearly shown that the 1:10000 / exposed sets had more percentage of yeast killed by sunlight when compared to the 1:1000 / exposed sets.
