Lab Write Up : Wisconsin Fast Plant

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

The scientific name for wisconsin fast plants is, Brassica rapa. The name of the division they are in is Tracheophyta. They are part of the family called crucifers. They are also distinguished by flowers in four petals in the shape of a cross. The Wisconsin fast plant produces harvestable seeds in approximately forty days. Wisconsin fast plants are part of the Turnips and radishes food group. Acid rain breaks down the nutrients in the soil that plants need.

Stage six happens on days nine through thirteen. This is the stage when Fast Plants will begin to develop the buds for flowers on its tip, or shoot meristem. Stage seven is on days fourteen through seventeen, and in this time the Wisconsin Fast Plants’ flowers will bloom, and pollination may occur.

TRANSITION The concept of improving plants has been around since the day humans started growing plants. This was accomplished by

In general terms, explain how the basic plant life cycle with alternation of generations is modified in angiosperms.

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.

Figure 1. shows the average leaf mass decomposition rate for invasive species leaves and native species leaves Results Explanation – In the experiment, we found that the invasive species leaves have a isopods faster decomposition rate than the native species leaves. The treatment used in the experiment differentiated only where the 1 gram (each) of the two different types of leaves were used. At the end of the experiment, the leaves had little to no moisture left to them and the 2 isopods were dead. Discussion – 1)

Just like everybody else in the novel Benjamin Rand’s takes the words of Chance when he talks about the garden and uses that as a huge metaphor about being a productive businessman. Ben Rand being the very best businessman that he is interprets what chance is saying to exactly what a productive businessman would need to do but the meaning to what Chance was saying has a little different meaning to what Ben thought. Chance is saying that when plants are like people, he really means that they start as a sprout and they grow to either become a flower and plant or a tree, and when they times comes from the sprout to die it will die peacefully after it has done all of its duties to why it was made. The sprout cannot do it on its own though. The

Then when they visit a new flower, some of that pollen rubs off inside and makes a seed.

According to the graph, B. vulgaris showed large preferences to temperature in relation to seed germination. For 3OC, it displayed the lowest germination percentage and for 5OC it displayed the second lowest germination percentage, in a close second to S. media. Both of these germination percentages were around 20%. However, at 10OC, the germination percentage increased to over 60%. Preferences to warmer temperatures cause this crop to be sown later in the season after the soil has warmed up. However, this makes this plant susceptible to competition from other weeds. Additional management techniques such as spraying herbicides will be needed to help this plant cope with its higher germination temperature.

Because plant cells have cell wall, they to divide by formation of membrane. The cell plate is formed by vesicle in the middle of the cell. The cell plate will continue to grow and become a new cell wall.

Flowers remain blooming when the sun is out for 1 or 2 days, being replaced by a seed capsule that grows large, and later splits open to release its seeds. The rhizomes that are found at the roots of these flowers, and the foliage contain a reddish juice. Over time the plants often form vegetative colonies, these colonies self-pollinate to reproduce.

Spores: The plants use sexual reproduction with the haploid cell of one plant, and the haploid egg of another plant. It makes a sporophyte cell, which feeds off of the parent plant until it is mature, and they are release in the air to reproduce.

Most plants can not fertilize on their own. Plants can’t just stand up and walk to find a suitable mate like us humans. This does not mean that plants are not able to reproduce. They have a special way to get their pollen onto their own or other plant’s pistils. Plants trade with pollinators. Pollinators are anything that transfers pollen to pistols. For example, bees are the most common but they are not the only pollinators. Bats are pollinators, so are humans, even the wind is considered a pollinator. Pollinators can be a living thing or and natural occurrence.
