Anthers and Stigmas and Styles, Oh My!

The basic question in which we are to be answering is "How do angiosperms reproduce?". Though the question is answered through the photos and their captions and explanation before hand may help. The scientific way is that the pollen is produced and released by the male part. The next step is to transfer the pollen to the female part and to then reproduce further through meiosis.





This image shows the stamen and the anther. The anthers are surrounding the stamen.
Those are the male reproductive anatomy for the flower. Below that is the carpel and stigma. Since both male and female parts are present the flower can be considered "perfect". Sometimes in flowers the male and female parts are in separate flowers, while in others there are both parts in the flower. 





This image shows the flowers male reproductive anatomy. This is referred to as the stamen. The stamen has stalk, which is called a filament, that comes from the base of the flower. At the end of the filament a part known at the anther is present. An anthers job is to produce and release pollen grains, or the plants male gametes. 






In this photo there is the carpel.(On the picture it is the lower green object) This carpel is the flowers female reproductive anatomy. The female parts has a stalk, like in the male parts. The difference in the stalks is that the female one has something called a style. The end of the style has a tip called a stigma. That stigma is very sticky so it can catch pollen grain and it is where the flower reproduces.




In this last photo all the other parts of the plants have been stripped away. When you split the stem in two you will be able to see the ovules being released from the stem.
