Gibberellic Acid Vs Rapa

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.

Plants are found everywhere on earth, up high on the ridge and down low in caves and caverns. The types of plants that live in these places depends on many factors. These factors are separated into two different categories, the biotic factors and the abiotic factors. Some of the biotic factors include, predation, competition, and habitat destruction. Plants with limited competition and large amounts of resources will be in a higher abundance than plants with limited resources and higher competition rates will be confined to areas and either out competed or will be the dominant species. Certain plants adapt to these factors and thrive and others don’t do as well. Some of the abiotic factors include, sunlight, water, temperature, and wind. These

It is also affordability, convenience, and effectiveness in nourishing plants; however it can also have disadvantages when using chemical based fertilizers. Plants will show signs of lacking nutrient the inorganic fertilizer was separate help over organic choices, it depends on soil organisms to first, break down the organic substance before the nutrients can be out. Inorganic fertilizer’s fast delivery elements and minerals eliminate this potential problem. Inorganic fertilizer, which is often reasonably priced, consists of mineral-based nutrients manufactured for instant application on crops. Unlike the organic variety, inorganic fertilizer does not need to decompose over time to supply nutrients to plants. Inorganic fertilizer contained balanced amounts of nitrogen, potassium and phosphorus to supply plants and to grow it faster. These are the substance of chemical gain from the processes in cultivating the first one is urea. Nitrogen as urea can be lost to the atmosphere if fertilizer urea remains on the soil surface for total periods of time throughout warm

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.

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.

In order to test this hypothesis and prediction, an experiment was conducted using a heterozygous F1 generation of Brassica Rapa seeds. The seeds were planted, pollinated, harvested (F2 generation) and germinated for observation. When leaves were visible, phenotypes (green vs. purple) were counted and recorded. The experiment took place over 13 weeks, spanning the full semester of General Biology Lab I. The sections that follow will detail the materials and methods used, the results of the investigation and an in-depth discussion of the outcomes.

Plants and animals are very important to human life. Plants and animals developed natural forms

Michael Pollan, author of The Botany of Desire: A Plant’s View of the World, addresses four major plant groups that have both changed for human needs and simultaneously changed human’s needs. While most gardeners, genetic engineers and other plant related professionals have long-believed that plants have evolved based on what we want or need to survive and in other words what we have “domesticated”, Pollan appeals to the plant’s view. Plants’ survival has been solely based on what humans desire both depending on their visual and stimulatory appeal along with their appeal to an appetite. Conversely, plants have used humans as a strategy for “getting us to move and think for them (page xx)”. Many plants have successfully maneuvered humans for

The Botany of Desire by Michael Pollen uses examples of four plants including the apple ,tulip, marijuana, and the potato, to describe evolution and how mankind works to help plants reproduce. We are a slave to things of sweetness, beauty, intoxication, and control. These four things are described by the different plant chapters in the book. We as people are driven to these kind of things because of the product we get, we subconsciously are working to make these plants more fit and therefore helping in their reproduction and evolution. With each plant chapter Pollen goes into depth about its contribution to the world and history behind the plant within human evolution. By using the examples he provides in the book helps demonstrate the ideas of how these plants contribute to the human body systems, evolution and ecology. To further explain these topics I chose to explore the apple, tulip and cannabis plants.

The tobacco plant like many plants contain a cell callus. A cell callus contains somatic undifferentiated cells and can be used to differentiate into specialized tissues of the tobacco plant, or any plant used, by being induced with the addition of different types of hormones, such as cytokinin and auxin. Cytokinin and auxin are mostly used in plant tissue culture simultaneously to provoke the formation of a plantlet or callus. There is a common use of Kinetin in plant tissue culture since when added it will promote cell division to initiate shoot tissues from calluses of the plant. Kinetin is a type of cytokinin hormone. In regards to auxin related hormones, Indole-3-acetic acid (IAA) is also commonly used since it promotes the initiation of roots for the root tissue of the plant. In this

Plants and animals are part of human's everyday life, their in almost everything humans use. There was a time that plants and animals were used only for food and some basic needs such as clothes, and protection. Later the doom of animals and plants would be when humans became smart enough to know how to domesticate both plants and animals. Animals who were once free roaming became controlled and plants who once were wild became secluded to a certain amount of land. This revolutionary idea brought about farming and invention of new tools as well as new purposes for animals besides meat. Domestication was important to early humans it meant that food surplus could be controlled and regulated. This is evident from the many fossils from settlements being found containing animal bones and seeds.

The novel "They came before Columbus" by Ivan Sertima is an essential part of understanding the key role plants play in life. Without even getting deeper into the novel one can interpret the title as saying plants were the first essential element and life form here on earth. Plants role in the human life is so important because they contribute to our economy more than anything else in the world. Plants provide food, oxygen, shelter, medicine, crops, and even clothes. The role of a plant is so essential because, they allow for the economy to thrive fully. Ivan Sertima was quoted saying, " The adoption of a plant is no simple matter". By Sertima quoting this he was demonstrating the complexity of plant life as a species. Sertima understand the

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.

     Plants are autotrophs that mean they are able to synthesize food directly from inorganic compounds, instead of relying on other organisms. They use carbon dioxide gas and water to produce sugars and oxygen

This means that humans not only need plants for eating, but also need their created oxygen to break the food down efficiently.
