Student Blog Post Assignment #7: Anthers and Stigmas and Styles, Oh My!

This is an image that depicts Anthers surrounding the Stigma on a flower. The Anther is the part of the Stamen where the pollen is produced. The Stigma is the part of the pistol where pollen germinates. The time when both the female and male parts are visible in the same flower, the flower is thought to be excellent.













This photo shows the Stamen of the flower. The Stamen is the pollen producing part of a flower, usually with a slender filament supporting the anther. Its the male reproductive anatomy of the flower. It consists of a Stalk known as the  Filament, and at the end of the Stalk is a part called the Anther.













This picture shows the female anatomy of a flower known as the Carpel, which is one of the leaf-like, seed-bearing structures that constitute the innermost whorl of a flower. One or more carpels make up the pistil. Fertilization of an egg within a carpel by a pollen grain from another flower will result in seed development within the carpel.












This is an image of a flower with the stamens, sepals, petals, and top of the carpel removed leaving it with just the ovary. The ovary was then cut open and the little green balls are the ovules coming in.









When ripe pollen from an anther of the same kind of flower catches on the stigma, each pollen grain sends out a tiny threadlike tube. The tube grows down through the style and pierces one of the ovules in the ovary. This process is called fertilization.
