What does your data show? Be specific and use pollen vocabulary. Interpret the data; does it answer your question? Was your hypothesis supported? Analyze all possible problems with data (error analysis).
In this Unit we have used many resources to collect data on our pollen and use them to correctly answer our question.
How does the pollen size correlate with the size of the pollinator?
We hypothesized that the size of the pollen correlates with the size of the pollinator; the bigger the pollinator the bigger the pollen.
To collect data we have done some background research and have used the SEM to take pictures of pollen from three types of flowers, Bellis perennis (Common name: Daisy), Primula vulgaris (Primrose), and Delphinium straphisagria (Delphinium). In our Pollen data table you can see the different sizes of pollen. The question is whether this size correlates with the size of that flowers specific pollinator.
The Daisy pollen had a length and width of about 36.3um and its pollinator, the honey bee, is about .4 to .6 inches.
The Delphinium pollen had a length of 42.2um and its pollinator, the humming bird, are generally 3-5 inches.
The Primrose pollen was the largest at 57um and its pollinator, sadly, is not the largest. Primrose is most often pollinated by moths at night and are around 1-2 inches including wingspan.
From this data we can see that the size of the pollen does not really correlate with the size of the pollinator. The Daisy pollen and its pollinator compared to Delphinium pollen work with the original hypothesis but in reality the sizes are all over the place.
Problems that occurred that could have affected our data may have been the mold that developed on some of the pollen grains. This could have distorted the true size of a pollen grain.
