Background

How do roses pollinate?

There are a couple different ways that roses can complete the pollination process. One of the ways is by insect pollination, as the insect takes nectar from the plant pollen will stick to the legs, hair or wings and then the insect will transfer the pollen to another rose. Another way roses can transfer pollen is through bird pollination, when the bird is hovering above the rose the wing movements with cause the pollen to stir and transfer to a different plant. This is also similar to wind pollination but instead of created wind it is normal wind that will transfer the pollen. Finally the last form is artificial pollination when a human will collect pollen from one rose and transfer it to a different rose.

Pollen Shapes and Sizes There is a lot of variance in size and shape between pollen of different plants. The size varies from approximately 10 to 100 micrometers. The shape can vary from round, oval, disc, bean shaped, and filamentous. The texture of the pollens cell wall can be very different as well. Another thing worth mentioning is that pollen color can be different between species but this can't be observed with the SEM so we will not be covering this in our experiment.The cell wall consists of the outer exine wall and the inner intine wall both can be very different. We will be comparing the exine walls of different pollens because those are easily viewed using the SEM microscope. Based on the size, shape, and appearance of the pollens exine walls we should be able come to a conclusion on whether or not the pollen of plants from the same family share similar pollen traits.

Rose Vs Primrose

Roses

In most roses they relate to many different types of fruits such: apples, peaches, cherries, pears, quince, apricot, almond, plums, blackberries, raspberries, strawberries, hawthorn. They're also valued in most European countries like Persia and Egypt. Many people use the rose as symbolism for the christian faith; they were also incorporated into food, medicine, fragrances and pieces of art throughout the Middle Ages. 

Primroses

Just to let people who don't already know this, the Primrose family, Primulaceae, is not related to the rose family, Rosaceae. They are mostly found in Asia that holds around 290 different species of primroses, there are also some species found in Europe. Primroses are mostly used for herbs and for decoration, the Europeans became fond of a species known as P. vera. Primula was given that name based off the Latin word primus which translates to "first". It was usually one of the first flowers to bloom in spring-time.
