The Story of the Seed

While the flowers of the plants didn't show many differences, the leaves showed much variation. Some were darker than others, some had different shapes, some were bigger/smaller than others, etc. The first plant we checked had leaves that measured 16cm x 14cm. The second one we checked measured 14cm x 8cm. The third we checked measured 26cm x 26cm. Nowadays, people can choose what plants to breed in order to get what they desire in a Brassica. This is called artificial selection.  For a breeder guarantee that they get the trait that they want in a plant, they must breed plants that already have this trait. This creates a purebred, guaranteeing they get their trait. The plants themselves, however, may have mutated  over time, altering their traits and genes.

                                                            The plants flowers didn't show that much variation. They mostly look the same. The plant's leaves have a lot of variation. Most of the leaves on the plants are different sizes and the outline is sometimes different. Plant 1 has a leaf height of 16 cm and width of 14 cm the stem size is 30 cm. Plant 2 has a leaf height of 14 cm and a width of 8 cm, the stem size is 14 cm. Plant 3 has a leaf height of 26 cm and a width of 26 cm, the stem size was 32 cm. Mostly now these days, people do selective breeding which is when people select certain types of genes for plants like brassica oleracea to make them better. Artificial selection is when people select certain phenotypes. Some mutations could contribute to the plants looks and genotypes. This could help with the plants traits and genes. Descent with modification   would be the most likely reason for the plants looks because it is the natural way an organism

  Which part (anatomy) or characteristic of the Brassica oleracea plants seems to exhibit the most variation (greatest number of different forms)? Which part or characteristic of the Brassica oleracea plants seems to show the greatest range of variation (biggest difference between one extreme and its opposite)? Use and include data collected from multiple measurements to support your answer. The characteristic of the Brassica oleracea plants that seem to exhibit the most variation is the ratio of length to width size of the leaves on the variety of plants. for example one of the plants the ratio from length to width of the leaf is 1.14 cm, another leaf's ratio of length to width is 1.75 cm, and the last plants' leaf is .93 cm. this shows a great variety and most variation in terms of traits of the plants. the greatest range of size between the ratio of the leaves is .93 cm compared to 1.75 cm. that is a .82 cm difference between ratio of leaf size between the plants

Looking at the garden  there's a lot difference is the heads' of the  plants and the roots. Some of the plants have long stems with little to no leaves, some have tall stems with several leaves. There were several other plants with vain like stems with little flower's other plants looked like they were growing cabbages and some looked like the cabbages had sprouted. 2 The reason  that there is so much variation  in the plants traits is probably because when farmers started growing the plants they breded the seed with others that had useful traits. It also could have been from the area that the plant was grown. 3 There was not much similarity all the plants were different from the others the main similarity between the plants was the color. 4 Since  there was not much similarity's in order for the plant breeders to get a new genotype and phenotype they would have to combine the genes of two selected plants. Or take the pollen from one plant and put it in another  fert

We are using the brassica orleracea flower. This is a picture of the whole flower. You can see the pedals, stem, stamen, and the carpel.  This picture shows all the parts needed for reproduction. This flower in particular has both a stamen and a carpel.  Here is a view at (2x). This is the stamen. It is a male part of the flower. There is a stalk that's called the filament. This is the base of the flower that is coming up from the stem. The top part of the flower is called the anther. That part of this flower makes and releases sperm cells. This part also makes pollen.  Here is a view at (2x). Here is a part of a plant that is called the carpel. The carpel has a stalk called the style. There is a sticky tip of the carpel that is called the stigma. This part of the carpel is sticky which means it can get pollen sticking to it.  This part of the flower has all the parts stripped away except the ovary. The sliced open ovule shows, the ovaries. These ovaries are immat
