Brassica Cosmetics

all treatments contain the same type of soil, are planted in the same size of pan, are exposed to the same amount of sunlight, and are maintained at the same temperature throughout the course of the experiment. ON THE TEST there will be a number of related questions about this section not just the question shown below.

In the dishes, I dropped the appropriate treatment into the center, where the marks were made. Next, I closed the petri dishes, taped them up, and let them sit at room temperature for a week. Then I opened them up to take two measurements. The first measurement was the number of seeds germinated. The second measurement was to measure the seedling lengths.

The experiment was begun by obtaining four 8 oz. Styrofoam cups and punching a hole through the bottom of them. This hole was for water entry or excess water drainage. Moistened soil was packed to the 1/2 full line in the cup along with 3 fertilizer pellets The cups were labeled the following: Rosette-H20, Rosette-GA, Wild-Type-H2O, and Wild-type- GA.(Handout 1) A small wooden applicator stick was obtained a moistened at the tip with water from the petri dish labeled ‘water.’ This was to be able to attract the seed to the applicator in order to place the seed from its original container into

The results observed do not correspond with the outcome predicted by the hypothesis. Despite the nature of the subjects of the experiments, no substantial growth was observed. Only one seed of the 36 planted germinated, and it could only survive for a period of a week. The one seed that germinated reach a height of 1.2 cm. Table 1 presents the average growth observed in each quad. Each quad had a total of 12 seeds. No seeds were removed during the course of the experiment.

The Wisconsin fast plant also known as the Brassica rapa belongs to the crucifer family of plants, closely related to cabbages, turnips, broccoli and other vegetables. Brassica rapa plants are used because they are viewed as model organism, a species that has been widely studied and can be breed in a laboratory. It is an ideal model organism because it has a short growing process. About 2 weeks after the plant is planted it will began flowering, possessing the ability to produce seeds at high planting density, is categorized as a petite plant size, and lastly has the ability to grow under continuous fluorescent lighting in a standard potting mix. This plants make it easy to track the genetic information passed from generation to generation

Firstly, for the setup of the experiment, two styrofoam cups were filled with two inches worth of standard, fertilized garden soil, next four seeds from from the garden seed, and the bird seed were placed an inch deep in separate cups. The seeds were blindly labeled, with one being labeled group A and one being labeled group B. This was so as to efficiently conduct a double blind experiment. The seeds were watered with approximately a teaspoon of water per day, and kept in a sunny windowsill. They were left in the windowsill for two weeks, and watered daily.

Add three seeds to the potting mix and cover seeds with little remaining potting mix. After the addition of the potting mix, use a dropper filled with water and water each cell until water drips from the wick. Then place the quads on a watering tray under the fluorescent light bank. Each cell should have an equal distance from the light bank. Quads should be three inches below the fluorescent light; the light should also be left on all day. Make sure all wicks are in contact with the mat that sits on the watering tray. Also watch out for the watering system regularly throughout the experiment. After four to five days record plants in the quads, giving their phenotypes in a table for each cell removed all but the strongest plant.

At the start of this experiment we were required to obtain a set of four Wisconsin Fast Plants, which are genetically, known as Brassica rapa. These plants have been, “originally selected under continuous fluorescent light to grow and reproduce quickly for research purposes, these petite, fast-growing plants have been used for teaching biology concepts” (Wisconsin Fast Plants). These four pots that contain our plants will be under our watch for the next 16 weeks where we will show our results at the end of the semester.

Today’s lab incorporated the six steps of the scientific method to the growth and development of their own Wisconsin Fast Plant, also referred to as “Brassica rapa” in the scientific community. My group’s experiment included researching the effect of acidity on seed germination. The Wisconsin Fast Plant or Brassica rapa, was originally created by Professor Paul H. Williams at the University of Wisconsin at Madison. The word Brassica can refer to many different plants such as mustard plants, cabbages, rapes, broccoli, brussel sprouts, cauliflower, kale, kohlrabi, turnip, rutabaga, and the Chinese cabbage. The Brassica rapa plants were created to help provide a better understanding and more research on the Brassica plant’s family diseases. Brassica rapa plants are in the Cruciferae family, and are named this way because all of the plants have 4 flowers in the form of a crucifix.

The second step of the experiment was to soak the seeds in water overnight. This action was made to prepare the seeds for germination and making them more softer and less rigid. The seeds were placed in a bowl and were covered by tin foil. It was set up on the refrigerator to minimize any outside interference that may come to it. After a full night of absorbing the water, the seeds were ready to start the next stage.

The control group in this experiment is the group that is grown normally to test the effects of the rest of the experiment’s independent variables. Growing Brassica rapa plants in the control group will allow the other science experiments to be compared to the normal growth of a common Brassica rapa plant. The normal growth of these plants will be important in measuring the other plants to see how their sizes compare and to show how an untreated plant would grow. Because of the nature of the control group, there is no null hypothesis since all the plants should grow at the same rate. If the correct amount of sunlight and water are given to the Brassica rapa plant, then they should grow as a normal Brassica rapa plant would. The purpose of this

This experiment will test the effects of gibberellic acid on both standard Brassica rapa plants and rosette Brassica rapa plants. Gibberellic acid is a growth hormone used to boost stem growth and speed up the germination process. The purpose of the experiment is to regulate the growth of both plants after being injected with gibberellic acid. Gibberellic acid will cause a change in the growth rate of both the standard Brassica rapa and rosette Brassica rapa.

The Brassica rapa has many common names such as field mustard, bird rape, colza, and keblock and is closely related to turnips, rapeseed, and cabbage. Wisconsin University researchers bred one species of the Brassica rapa to have an extremely short life cycle (seed-to-seed thirty-five to forty days) for a model organism in education and experiments. In addition to their short life cycle, they are ideal for these situations because they can grow without natural sunlight, without much space, they do not use an excess of water, and the changes can be seen from week to week.

Brassica Rapa is a widely-studied plant in the field of Biology. Brassica Rapa is also known as the vegetable crops that many people often cook in their kitchen or harvest in their gardens: cabbages and turnips. This herbaceous species derived from the genus of Brassica and the family Brassicaceae (1). Worldwide, this species is recognized as one of the most fast-growing plants that many biologists are found to experiment on when testing the effects of various variables. When teens are in the process of developing, they begin to produce steroid hormones in which a sudden growth spurt occurs in the body, such as testosterone and estradiol. While the same process occurs in plants, many plants produce brassinosteroids when they are in process of developing in terms of body size (2).

Cosmetics are substances that are applied onto the body and/or face to enhance a person’s looks or scent. Cosmetics can be make-up which is mostly used by women and it is to enhance a female’s appearance. It is normally applied to face, hair, and body. Cosmetics has been used throughout society since Ancient times. In Ancient Egypt, cosmetic chemistry was being used before anyone knew it related to chemistry. Cosmetics was being used for many reasons in Ancient times. It is said that Cleopatra bathed in donkey milk to keep skin smooth, this is an example to show that chemistry is being used for the benefit of skin care. Skin care is another example of cosmetic chemistry being used. Skin care has been an important factor in society. Skin care has been around since 3000 BC in Ancient Egypt. This was prepared by natural materials.
