Anthers and stigmas and styles, oh my!

This is a picture of the plant before we started to dissecting it for 

for scientific reasons.

 

This is a picture of a group of Anthers surrounding the stigma.The anther is connected to the Filament and together they make up the stamen. The Stigma is connected to the style  which is connected to the ovary.  They are all part of a prefect flower because the flower has both female and male parts.

 

This picture of the carpel the top is the Stigma, in the middle is the style than the ovary. This flower has more than one ovule. In the ovule is where female gametes are produced.

The stigma at the top of the Carpel, and is sticky. The stigma is where pollen grain frequently lands. Some flowers have several Carpel mixed together to from a single reproduction structure known as a compound Carpel.

Fertilization/Meiosis

First a pollen grain has to land near an Ovule. The grain will than split and grow a pollen tube with two haploid sperm nuclei. When the Pollen tube reaches the female gametophyte one sperm fertilizes the egg. Then fertilization produces a diploid Zygote (new plant). The Zygote turns into an embryo, then it will encase into a seed. The seed has three generation of the life cycle. The seed has three generation of the life cycle. The Seed Coat is part of the older generation, the haploid cell in the embryo is part of the female gametophyte, and the embryo in the new plant.
