Final Blog Post
1) The part of the plant with the biggest variation are the leaves because they come in many different sizes and shapes like on my plant it has oval leaves that are very large with green veins. The characteristic with the most variation is the stem of the plants. Some plants have normal green stems but most have purple stems with purple veins on the leaves. Also some variation are in the plants height. My plant is the shortest plant in the garden bed and the plant behind it is the tallest one and some are in the middle, but no brassica plant is the same height.

2) There is a lot of variability in the forms of the brassica plants because of genes and traits. The brassica plants used selective breeding to give their children different traits to see which have an advantage which is smart for the plants to do which changes up the plant's genes. With that the effect of descent modification happens and the new and original plants pass down their genes. But in the beginning that was only natural variation. Now we use different plants to breed with the brassica plants, which is called artificial selection. Finally sometimes it doesn't need breeding to have change in genes. Sometimes there are mutations in some plants that get exposed to something which can change the plant's genes to give it an advantage or disadvantage, but in the end once the plant passes on its genes it will also pass on the mutation it got to it's children which will end with more variations of brassica plants.

3) The most consistent part of the plants has to be the stems. All plants have relatively the same thickness and coloration of stems. This might be because of descent modification and how the past Brassica plants had these types of stems and passed it on to their offspring. It also seems that there hasn’t been any big mutations to mess this phenotype either.

4) What I believe plant breeders might have to do is use artificial selection or to make a mutation happen where the stem gets affected and changes. The mutation to me, I believe would be the hardest.  It would be hard because you would have to get the right mutation that would affect the stem and change it’s form or color. Artificial selection would be easier because you just have to pair one of the brassica plants with a different plant with somewhat of the same genes and wait some time to see what phenotypes change and maybe the stem will change as a result of the brassica plant mating with the other species of plant.

Blog Post #7: Anthers and Stigmas and Styles, Oh My!

Blog Post #7:        In order for our plant to have been planted in the first place, we would need seeds. We got these through a very important process. It all began with another plant, that when it got big enough, began to grow flowers. These flowers would have multiple parts, including the anthers, stigma, stamen, carpel, and ovules. First, the flower would use the anthers to produce pollen, which is basically the sperm for plants. Then a Bee would pick up that pollen from the flowers and bring it to another flower. This bee would land on the carpel, and the pollen would get stuck on the stigma, because of their sticky tip. Then, that pollen would be transported to the ovules to fertilize the eggs, which eventually become seeds for another plant.        Here is an image of the flowers of our plant (or at least one near our's). In this image, it shows the anthers and the stigma of the flower, both which are parts of the flower reproductive system. These parts are the male

Post #6 The Story Of The Seed

1) So when my plant uses Photosynthesis it makes energy for it self to survive. Photosynthesis begins when the plant receives water, sunlight, and carbon dioxide. After that it dos the process and releases oxygen because it doesn't use a lot of it and it also produces glucose or sometimes food like fruit because it uses it as energy. Then when the plant breathes out oxygen all the energy it made is used. It is used for plant growth, flower for\ation and fruit production. Since the energy is used for plant growth that means it has the energy of its cells to begin to multiply by the process of mitosis. The beginning of mitosis is interphase, when the cell is preparing itself to divide. Then comes prophase when the chromosomes of the cell are now visable. Then metaphase comes and the chromosomes align in the middle for the fibers to attach to them. Then anaphase comes and the spindle fibers begin to split the chromosomes in half. Then telophase and two nucleus have formed and the cell
