Pollen Morphology Tree:

\

The reason that we thought that the rose and winter pansy would be closely related is because they both are flowers that bloom in the winter time unlike the Tulip bloom in the spring. Another reason that we thought that they were closely related is because when you look at there pollen there are things about them that look similar.

Analysis:

As you look at both tress you see that they have the same to flowers connected to on another. They are most alike when you look at all three DNA sequences. They have no common characteristics to one another but when you look at the pollen and realize that they are both winter blooming flowers.

Analysis

Firstly, it is important to realize that tulips bloom in the spring and winter pansys as well as roses bloom in the winter.  Our original hypothesis was centered on the assumption that winter pollen was more complex in morphology, than spring pollen due to the fact that it survives the winter still being intact.  Our specific data showed that the red tulip was a monolete, meaning that the microspore of pollen had one aperture and its surface was scabrate.  This was extremely different from the winter pansy, which was what we expected, but there were not as many similarities between winter pansy and the rose as we had hoped for.  One major difference between the rose and winter pansy was the size of the pollen under the SEM microscope.  At the magnification of 2000x rose pollen had the width of 45um and the winter pansy pollen had the width of 75um, and finally, the tulip pollen had the width of  16.1um.  These data show that there are significant differences between all of the information we collected, but with more data we might have been able to reach further conclusions.
