A Brassica rapa belongs to a field mustard genus and its common name is the cabbage plant (Anonymous 2001). In this experiment, the effect of the gibberellic acid was tested on a standard and dwarf plants. A dwarf plant is not the average height of a standard plant. The gibberellic acid has a chemical substance that could increase the height of a plant. The gibberellic acid would determine whether or not it had an affect the plants height. The null hypotheses of the tested plant are that the average mean of the treatment plant would not have a difference on the height of the plant whether it water only to gibberellic acid. It not just a Gibberellic acid, but it has water as well.
Methods
The material that were use are: Brassica rapa seed,
Two members of the group were instructed to visit the laboratory each day of the experiment to water and measure the plants (Handout 1). The measurements that were preformed were to be precise and accurate by the group by organizing a standardized way to measure the plants. The plants were measured from the level of the soil, which was flat throughout all the cups, to the tip of the apical meristems. The leaves were not considered. The watering of the plants took place nearly everyday, except for the times the lab was closed. Respective of cup label, the appropriate drop of solution was added to the plant, at the very tip of the apical meristems.
The Brassica rapa plants were bred to live in the colder states of America, such as Michigan and Wisconsin. Up there they have very few times it is actually warm enough for plant growth. So to take advantage of those few short moments, Dr. Williams bred a ...
We used wheatgrass were 40 wheatgrass seeds, two empty pots, soil, and water. We first added soil for both pots and 20 wheatgrass seeds in each pot. My partner and I decided that we label pot one experiment which is “sugar and water” and pot two control which is “water” only. The experiment was for almost four weeks we had to make sure both get the same room temperature and water, so we can see the results after this amount of time. Both pots had same room temperature so both can have the same amount of sunlight also, the same amount of water which is a glass of water from the sink once a week. In the experiment pot we added a glass of water with one teaspoon of sugar and the control pot glass of water. Every week we used to see both pots grow almost the same. At the end of the experiment, my partner and I measured the length for both plants and we recorded the average for each plant, so we can know the rate of growth
For this experiment the null hypothesis is that the intensity of the step rate test (High and Low) has no effect on the persons’ heart rate and recovery time. While the alternate hypothesis is that the intensity of the step rate test (High and Low) has an effect on the persons’ heart rate and recovery time.
Abstract: Gibberellic acid is a plant hormone that is used to stimulate growth and fasten the germination of plants. When Gibberellic acid used on plants, it produces bigger and fuller leaves following by elongating the stems. This experiment was designed to determine the effect that Gibberellic acid will have on the growth of a seed germination. As performed in class, three types of radish seed were treated with Gibberellic acid to see the effects the acid will have on those three seeds. During the treatment plan, the three seeds received a different amount of acid and water five times a week. For instance, Seed A got approximately 2.5ML of Gibberellin acid, seed B got 5.0ML, and seed C got 10ML, following by seed A getting 17.5ML of water, seed B getting 15.0ML, and seed C obtaining 10ML of water. However, based on this treatment plan, seed A and B showed no growth. While, the seed that consumed more acid, which was Seed C showed rapid growth. In this case, the only possible explanation for this surprising result could be that the Seeds
Brassica rapa, a variety of the mustard plant, was used for food as far back as the Roman Empire; however, it is difficult to distinguish where the plant originated, as it is spread across much of Eurasia (Guo, Chen, Li, Crowling 2014). This plant is used in many experiments due to its short life cycle, which hovers around six weeks, and is thus considered a ‘fast plant’. We are using Brassica rapa because of its relatively small size and short life
Tacitus is considered by many to be the greatest Roman historians to ever live. Clearly his knowledge and skills are fully demonstrated in his writings Agricola and Germania. Tacitus captures his readers attention witnessing different ethnic groups and there various customs from each other. Agricola focusses on Tacitus father in-law Julius Agricola. Because of Agricola Tacitus saw ethnography on the many people of the ancient Britain. In Germania Tacitus writes about the different Germanic groups of the time. Tacitus in both of his writings portrays the cultures, traditions, and establishments of many different ethnic groups. Cornelius Tacitus was born 56 AD in southern Gaul which is now modern Providence. In 75 AD he moved to Rome and became an orator. A year later he married the daughter of the consul Cn. Julius Agricola. Tacitus is best known writings included Agricola (97-98), Germania (98), The Histories (110), and The Annals. Harold Mattingly (1884-1964) translated Agricola and Germania. J.B. Rivers published his translation, with introduction, and commentary of Germania in 1999. How does reading Tacitus’s Agricola and Germania help provide a better understanding to classical Rome? Through Tacitus’s writings we can pick out important parts of
The fair testing will be carefully checked so the results do not come out to be void. The light intensity will be changed for it is the only variable used in the experiment. Though the temperature, watt of the bulb, amount of water, size of the plant and posit...

This plant was given the name Skunk Cabbage because of its distinctive “skunky” odour that it emits due to the breaking and tearing of its leaves. This odour will permeate the area where the plant grows, and can even be detected in old, dried specimens. Although, it produces such a pungent smell, it is not a poisonous odour; but it attracts its pollinators like flies, stoneflies, bees, and beetles and also serves another purpose to discourage large animals from disturbing or damaging this plant. Although, this plant is very unique due to the “smelly” odour it emits, it is also exceptionally due to its ability to maintain an approximate constant temperature of 20 degrees around it spadix, which bears both male and female flowers) even in below freezing conditions (Takashasi et al., 2009; Ito-Kikukatsu et al., 2004). This ability to grow in such conditions is due to its thermogenetic properties of the species of plant, the Skunk Cabbage is a thermogenic plant that blooms in early spring and maintains temperatures, as seen above in all-weather conditions. In this essay, I will focus on the Skunk Cabbage and its unique characteristics that allows it to survive and prosper by the means of being a poisonous species, distinctive odour, and unique metabolic mechanisms
The plants of the genus Brassica include species very important for research and agricultural purposes including vital vegetable and oilseed crops (Augustine 2013). Research for these plants typically aim to increase their nutritional value and develop traits such as herbicide tolerance, sterility, and disease and pest resistance (Gupta 2012). One plant that can be used for research is Brassica rapa, in the form of Wisconsin Fast Plants, which are a rapid cycling variety that can be used for genetics investigations (Kinds Plants 2014).
To make the test fair I will use the same amount of water and the leaf
Comparing the Growth of Pea Plants Grown in the Light and in the Dark Aim: To compare the vertical growth and weight gain of pea plants grown in the light and in the dark. Background Knowledge: Photosynthesis forms the basis for this experiment. This is the process by which a plant makes food for itself from the raw materials around it. The energy needed for photosynthesis comes from sunlight, which is the variable for this experiment.
Plant defences are those mechanisms employed by plants in response to herbivory and parasitism. According to Hanley et al. (2007), “the tissues of virtually all terrestrial, freshwater, and marine plants have qualities that to some degree reduce herbivory, including low nitrogen concentration, low moisture content, toxins or digestibility-reducing compounds”. The type of chemical defence may be species specific (Scott 2008). The defences that plants possess may be in the form of chemical production or in the form of physical defences such as thorns or spikes and even through reinforced, rigid leaves. “The compounds that are produced in response to herbivory can either have a direct effect on the attacker itself (e.g. toxins or digestibility reducers), or serve as indirect defenses by attracting the natural enemies of the herbivores” (Bezemer & van Dam 2005). This essay will focus on chemical plant defences and in particular the effects of terpenes, phenolics, nitrogen-based defences as well as allelopathy in plants.
This lesson is designed to review and reinforce a few important concepts about plants (e.g. Needs, parts, sequence of planting) and to also guide the students through applying a few scientific inquiry (e.g. Making observations, experimentation, discussion, reflection, reporting results etc.). The students have previously planted corn and bean seeds and today’s lesson has provided the students a chance to see the results of the planted corn and bean seeds. Additionally, seeds have been planted under and growing under the following conditions: without water, and without soil. The students see the results of these seeds planted under these conditions for the past week. Two plants in particular have already been grown their growth has been
