Blog post 5: Flower Dissection

A Brassica plant is fertilized when pollen from another plant is moved to another plant by the wind or a pollinating insect. Once on the flower. the pollen goes to carpel and then to the ovules at the bottom of the flower.

These are the anthers, they are the male part of the flower and they hold the pollen grains, which contain sperm cells.

The male reproductive part of a flower called a stamen has a stalk known as a filament that comes up from the base of the flower and on top of the filament is the anther which releases sperm cells in the form of pollen.

Shown below is the female reproductive part of a flower known as the carpel. The carpel contains a style and on top of the style is a sticky portion that catches pollen known as the stigma.

Inside the bottom of the carpel is the ovary that contains ovules, which are unfertilized eggs which when fertilized produce seeds inside a fruit.

We are experimenting with some small brussels sprouts. This plant has thick leafs and is on the shorter side. The offspring will appear exactly the same but some small differences like how many leafs there are. The off spring would get its traits from its parents seeds. The seeds begin meiosis when they are planted in the ground. They divide and grow and brassica pass their genetics through their seeds. The offsprings would not look the same because the have a combination of both parents genetics ant the environment can can be different too. The offspring have their own genetics. If we were to grow the plants next to each other for many generations they'd eventually mix. I feel they look so differently because they may have been grown in different spots or environments so they'd have different traits to the others.

Fertilization in a Brassica occurs when pollen (held on the anthers) from another plant is transported to another plant by the wind or insect. Once the pollen gets to another flower, it makes its way down to the carpel to the ovules located in the base of the flower.

Here is the male reproductive part of the flower, known as the carpel. The carpool has a style and on top of the style is the stigma that has a sticky tip that collects the pollen. 

Inside the base of the of the ovary is the ovules. Ovules are immature, unfertilized eggs.

We are experimenting with a small sprout of Brussels sprouts. Our plant has three, thick leaves, and is fairly short. The offspring of this plant will appear exactly like its parent but different in its own little way probably in the way the leaves are arrange. The offspring would get its traits when the parent produces its seeds. When the seeds are planted the cells inside begins meiosis. They begin to divide and grow. Brassica oleracea pass their genetics through the seeds they produce.
Offsprings will look similar but not exactly the same, because they inherit the parents genetics, but the living conditions could be different. They have there own set of genetic code in each seed. If we were to grow them next to each other for several generations they may mix genetically.I believe that the ancestral plant for our plant was grown in sightly different areas and over time it began to evolve to fit with their surroundings.
