Blog post 7

Here is our flower before even dissecting.




















This image shows the anthers around the stigma on the flower.  The anther is a part of the stamen that produces pollen.  The stigma, which is surrounded by anthers, germinates the pollen that comes from the anthers.  The stigma is also a part of the female reproductive organ of the plant.



This picture shows the stamen. The stamen is the pollen producing reproductive organ, it has 2 parts, the anthers and the stalk.  When undergoing meiosis it produces pollen.





















In this picture you can see the female anatomy known as the Carpel.  The Carpel is the seed bearing leaf like structure that make up the pistil.


This is the flower with everything removed and the ovary opened and the ovules coming out.



From all this I eventually learned how plants fertilize.  First off there is something called self pollination which isn't super common, but for plants that can't obtain pollen themselves they get it from animals or wind.  For example, a bee will come over to a flower and as it leaves it has pollen on it, so when it moves to the next flower it will have pollen on it and it may be pollinated. Once the pollen reaches the ovaries it will from a zygote and then create a seed.
