Student Blog Post Assignment #10: Anthers and Stigmas and Styles, Oh My!

This is the pedal of the flower before it was cut. It is on both genders of the flower to collect more sunlight.

This is a picture of one of the flower's stamen, the male reproductive part. The tip is the anther and the stem is its filament.

This is a picture of the carpel of the flower (lowest part), the female reproductive part. The tip is the stigma, the mid-body is the style, and the ovary (not shown) is at the bottom.

This is a picture of the plant's ovary cut open, revealing the ovule.

     The reproductive system of the flower works on the same general basis as many other organism, through connecting sperm and egg cells. The stamen, the male reproductive piece of a flower, is made up of an anther at the top and a long filament connecting it to the ovary. In the anther, meiosis takes place to produce haploid male gametophytes (also known as pollen grains). The carpel, the female reproductive piece of a flower contains the ovary at the base of the flower, the style, a stem extending upwards from the ovary, and the stigma, the top of the style. The stigma is sticky so it can catch pollen grains in it and transport them down its pollen tubes to its ovule where it combines with an egg cell to form a zygote.
