This is a view of the female anatomy of a flower called the carpel. And this part right here is the part that sticks out and capture the pollen seeds.

this is male reproductive anatomy of a flower, known as the stamen. and it's similar to a male reproductive system because it also have a part called anther and this contain the plant's male gametes and it's also where the pollen seeds get release.

this image is the anthers all over the stigma, the anthers are like sperms and the stigma is like a female reproductive system. 

this is a picture of a plant's ovary and this part contain the ovules.


Summary


So basically, how fertilization occurs in flowering plant species like Brassica oleracea works is by doing self pollination and it's mean the plant does the whole reproductive system on it's own and how it works is the plant have a part called carpel and it have a job of capturing pollen grains which contains sperm, and those pollen grains are coming from the stamen, the male part of the plant. After the pollen grains get captured on the stigma of the the carpel, it will get transferred down to the ovary where the plant contains the ovules that are immature and unfertilized seeds, and this part can be found under the carpel. So like that the pollen grains get to the unfertilized seeds and then turn create an embryo that has the potential to become a new flowering plant of the same species. And after that, those unfertilized seeds will become a new fruit.

1.After inspecting the plant outside, overall the plant didn't seem to change much except for the flowers like the has definitely grew out to be longer and few of them tend to bloomed out but the variety of them is definitely low since there are plants that have from 2 to 5 flowers max. Other than that, the plant just got a little taller and bigger.
2.The reason of why there are so many variability in the domestic forms of Brassica oleracea is because farmers plants them in so many different environment like hows little of the water resource is or how the have plenty of water, etc...And based on those environment, the farmers has to make the best out of their plants by combined the plants with the traits that suit the environment the best and that is called descent with modification, and there are also many more ways of how the farmers do it like traits, selective breeding, artificial selection, genes, these are ways farmers chose the plant that is producing the most and so they keep those good plants and kill the rest which are all bad plant that aren't producing or as much. And natural variations, mutations are when the plants adapt to the environment them self and trying their best to be fit with their own particular environment. All of these methods above are the reason why there are so many variability in the domestic form of Brassica oleracea.
3.I say it would be the flowers because they all look similar and this particular part of the plant is always similar is probably because having a flower like this or many of them like it wouldn't effect the outcome of the plant so both farmers and natural don't have to change it.
4.In order to breed out flowers like our's in the picture below, the farmers have to find a similar flower with a slightly different color and then breed them together and it will most likely result in a plant with a different color flower from the standard color--it would most likely resemble the parents' flower color.
