Plant Hormone Lab Report

In this experiment we are testing the effect of fertilizer on the speed of plant growth. We prepared a 4 quad cell, 1 control group and 3 experimental groups. So, we had one with no fertilizer, one with three seeds of fertilizer, one with six seeds of fertilizer, and lastly, one with nine seeds of fertilizer. The plants that we grew were called Wisconsin Fast Plants, members of the crucifer family. These plants are small and easy to grow, but for optimal growth they require continuous fertilizer, water, fluorescent light, and temperature between 18 degrees Celsius and 26 degrees Celsius 24 hours a day. Fertilizers are substances that are put into soils to increase the growth of the plant. There are two different types of fertilizers, synthetic

Four cups of equal size were filled with one cup of garden soil. Lima beans were planted at an equal depth (one inch as instructed on the bag). Every day, for 33 days, each plant received one half tablespoon of the specified liquid. Beans one and two got one half tablespoon of water each,

If feeding efficiency and reproduction have a direct correlation, and a population started with equal proportions of individuals with each of three feeding types, metal spoon, metal knife, and plastic fork, the frequency of the population with metal spoons as their feeding structure will increase in the next generation. While the frequency of metal knifes and plastic forks will decrease. Furthermore, since the organisms with the metal spoon feeding structure have a higher fitness level, this population will evolve by natural selection to a point where the metal spoon phenotype will be in abundant. While the organisms with metal knifes and plastic forks phenotypes will decrease in frequency due to the lack of reproduction. Eventually, if this population persist overtime, most of the organisms, if not all, will have the metal spoon phenotype, while very few, if not any, will have the metal knife or the plastic fork phenotype.

The hypothesis behind this experiment is that the Gibberellic acid has a positive growth effect on the plant and causes it grow larger in height.

The purpose of this experiment is to observe the effects of Sodium Chloride (NaCl) on the germination rate of Wisconsin Fast Plants.

However, for each quad, the fertilizer used for the control was added altogether with the fertilizers being studied. Since the only plant that presented growth was in the control quad, it becomes necessary to explore the effects of excess fertilizers, and furthermore, excess nitrogen, would have in the development of the fast plants. Although Nitrogen is one of the elements most living organisms require, some studies have showed high levels of nitrogen can cause toxic stress to some plants, to the point where growth can be inhibited. (Yu et al.

The first lab was conducted to analyze how germination affects the rate of cellular respiration in lima beans compared to dormant seeds. In order to

i.When testing for hypothyroidism, why is the free T4 level an important measurement? Predict what the TSH and T4 test results would indicate in someone with primary hypothyroidism. Explain your answer. (100 – 200 words, 5 marks)

I learned that anaerobic is an organism or tissue that is living in the absence of air or oxygen while aerobic is involves the organism or tissue receiving and requiring air. Furthermore I learned about the anaerobic cellular respiration that uses an electron acceptor rather than oxygen to complete metabolism using electron transport-based chemiosmosis. Also in this reading I learned about fermentation which is an anaerobic process in which energy can be released from glucose even though oxygen is not available.

While experimenting with the green beans, the seeds exposed to the organic plant food germinated within five days of the experiment and the seeds exposed to the chemical plant food germinated within six. The seeds that acted as the control had been expected to grow the least, however, it was surprising that they did not grow at all. Both the chemical and organic fertilizers proved to have positive results on the plants. It was also unexpected when the seeds exposed to the chemical plant food surpassed the height of the other experimental seeds after being shorter. The predicted reason for the increase in growth with seeds given Miracle Grow was because chemical fertilizers automatically store up the nutrients and disperse it constantly throughout

Pea plants, along with many other plants and vegetables, are taken for granted. Without them, much of the world would be

For this lab conclusion I will discuss the pros and cons of administering Human Growth Hormone (HGH) to a 7-year-old, Scrappy Snuffleupagus. Scrappy Snuffleupagus’s father wants him to take HGH because of his height. I will also discuss the pros and cons of administering Human Growth Hormone (HGH) to a 75-year-old, Shaggy Snuffleupagus. Shaggy is slowly but surely shrinking and becoming rather frail.

Advances in the field of medicine gave way to a new field of bodybuilding. The most influential bodybuilder in this new era is Dorian Yates. His experimentation with the new anabolic steroid, “Human Growth Hormone”, allowed bodybuilders to surpass their natural potential and put on a large amount of muscle. When others heard about this new miracle steroid, they quickly flocked to get their hands on it. Human Growth Hormone “HGH” did yield some bad effects, but that did not stop Dorian from using it. It has been shown to increase the amount of smooth and cardiac muscle surrounding the organs, which makes them have to work harder in order to maintain their regular functions. One of the biggest concerns is the enlargement of the heart (also known

Human growth hormone, a substance produced in the human body, is now being sold over the Internet. Companies are marketing the product as an anti-aging product. At the web-site, http://www.awakenhgh.com, the company claims that there is a possibility that one can "stop the aging process." On the home page, they claim that the product can reduce fat and cellulite, increase energy and muscle tone, elevate mood, improve sexual performance and sleep, remove wrinkles, balance cholesterol, re-grow and re-color hair, and more. The product is a dietary oral spray that they claim contains a product that is "identical to the growth hormone manufactured in the human body" and is designed for oral consumption. They also

This data shows a strange outcome, in the hypothesis; it says that “If acid is introduced to the seed during germination, then the roots will not grow as long as the seeds that are given water”. This statement proves to be untrue, because the roots grew longer with stronger acid than weaker acid, and in some, cases, grew better with strong acid than it did in water. This may be true because of the acid growth theory. The acid growth theory states that auxins cause the elongation of stem cells by promoting wall loosening. It was determined that this wall loosening is caused by hydrogen ions. This idea and subsequent supporting data gave rise to the acid growth theory, which states that when exposed to auxins, susceptible cells excrete protons into the wall at an enhanced rate, which in turn decreases the pH in the wall. The lowered wall pH then activates the wall loosening process which is essentially doing the same thing as the auxin hormone.
