Mitosis is the process of a cell splitting, and occurs at all times. It is essentially how the body grows, and occurs more rapidly at a younger age, as that is when you grow your fastest. The phases are Prophase, Metaphase, Anaphase, and Telophase.
Prophase - The chromosomes become visible as paired chromatids and the nuclear envelope disappears. The first prophase of meiosis includes the reduction division.
Metaphase - The chromosomes attach to the spindle fibers.
Anaphase - The chromosomes move away from one another to opposite sides.
Our project was to see if you can grow quality potatoes using less water than what's recommended. To do this, we had two groups of 20 potatoes, one we'd water weekly and the other bi-weekly. In the end, the only three that ended up growing were part of the less often watered group, most likely due to lack of rationing and planning when watering the plants.
This research matters because 70% of the water usage goes to agriculture. Majority of this water is taken from the Ogallala Aquifer, a massive table of water underground, that spans 8 states. It is predicted that at the current rate, it will run dry within 50 years. If this happens, it will take 6,000 years to naturally refill. Even if agricultural water usage is cut by a small fraction, it will greatly reduce the amount of withdraw worldwide.
If I were to do this differently, I would have properly measured and rationed out the amount of water we used, and how we used it.
In this project, I learned that you can oxidize a plant leaf even when it isn't attached. In this experiment, we were to make cutout circles of leaves, put them in a syringe, and make them sink to the bottom of a syringe by creating a vacuum. We would then put them into water under a certain kind of light. When I did this experiment, I put 10 cutouts in the syringe. I got all the leaf cutouts to sink to the bottom of the syringe. However, when I put them under both lights, the cutouts did not float for longer than two minutes. The purpose of this experiment was to visually represent how oxygen interacts with different kinds of lights.
This was a small project in which we dropped some beans and corn into a cup full of tissues and filled it with water. We had freedom to choose how many beans and corn we put in the cup, the amount of water, and the type of water. I put way too many beans and corn to count, put I just put enough fountain water to dampen the tissue. We did this experiment to find out whether the plants we grew would be a monocot or a dicot. I predicted that mine would not grow at all. However, I never had any direct reason why I thought this way. Maybe it was because I thought there were too many beans, too much water, too much tissues, or maybe the other way around. However, I just found it strange that tissues and some water would be enough to grow an actual plant, therefor I doubted it. As the plant grew, I found myself being quite surprised, as the beans broke and little roots were coming out of them. I also observed that the edges of the tissue were changing colors from light brown the black, as if they had been burnt. I didn't think much of it, however, and assumed the plant wouldn't reach out of the tissue. After a few days, I realized that my prediction was completely wrong. As a result of all the beans and corn, my plant had the most plants out of pretty much anyone. Also, the amount of tissues and water I put in had to be just right, because my and a couple others plants grew the absolute best out of anyone's. Some people's never reached above the tissues. Also, I learned that the fountain water was the perfect type of water to grow a plant in. I eventually moved the plant to dirt, but because I'm no gardener, it didn't grow much more. However, I am proud that the plant grew as much as it did.
