Flower Dissection




These are the lovely petals, there are 6 petals and they are neither male nor female, they are simply petals. Since there are 6 petals and 6 is a multiple of 3 it makes the flower a monocot . You can also see on the leaves that the veins run parallel which is a trait of monocot plants.
This is the stamen of the flower.The fillament supports the brown pollen producing anther. Both the anther and filament are male flower parts
The stem part of this flower structure is called the style and the small brown part at the top is called the stigma. Along with the ovary these parts make up the female part of the plant called the pistil.

This is a picture of the flower ovary under a microscope. They almost look like peas in a pod!
* This is a cross section of the stem of the flower, this just shows that the plant is a monocot as the vascular bundles are all over the place.


Here is what the flower's pollen looks like under the microscope. Funny, to me it looks like a lot of grains of rice.
 
This flower is a monocot because of its parallel veins, number of petals, and its stem.
 
Pollination:
Pollination is needed for fertilization of the plant. It occurs when pollen from the anther is transfered to the stigma of a plant. Therefore the plant parts involved in pollination is the pollen producing anther and the sticky recieving stigma. There are two types of pollination. Self-pollination, when a plants pollen pollinates its own stigma. The benefit of this is that if is easy and fast, the pollen does now have to "fly" to another plant. But there would be no variation of species this way. The other type is cross-pollination, when a plants pollen lands on another plants stigma. This benefits the species better than self pollination as it allows for more variation in the genes.
