History and Application of Plant Tissue Culture HORT 306 Term Paper Huan Wu 1. Introduction Tissue Culture means the tissue or cells that separated form the origin organism. Tissue culture technique is a very important tool for human society. Tissue culture allows sample accurate and fast copy of advantage individual, making a lot of miracles based on science. It shortens the time for normal selection, and spread out controllable advantage traits. Tissue Culture plays key role in crop…

Epigenetics is defined as the study of changes in organisms resulting from modifications in gene expressions.The use of stem cells prove to be a vital part in the course of Epigenetics.Stem cells are characterized by two traits. They are self-renewal, able to divide into more identical cells and pluripotency, which allow the cells to become any kind of cell such as Erthrocyte or osteoclast.The relationship between epignetics and stem cells paved a pathway to an experiment relating to the…

Genetically modified organisms created by genetic engineering began with Watson and Crick’s model of DNA. “Some benefits of genetic engineering in agriculture are increased crop yields, reduced costs for food or drug production, reduced need for pesticides, enhanced nutrient composition…

The circadian clock regulate the biology and behavior of a living organism throughout a day (about 24 hours). It can be affected by external factors such as daylight or darkness of the environment. The circadian system can modify the behavior and physiological functions to adapt the environment. For mammals, the suprachiasmatic nucleus (SCN) are the central circadian clock of our body, which is located in the hypothalamus. Meanwhile, there are peripheral circadian clocks which located in most…

Gene modification is the process of altering the DNA of a living organism such as humans. CRISPR-cas 9 is a genome editing tool where scientist and doctors remove, add, or alter sections of the DNA sequence. It has the capability to treat chronic diseases, create designer babies, and improve the quality of life. Therefore, doctors should be allowed to perform gene modifications on humans. According to Centers for Disease Control and Prevention, in 2012 “one hundred and seventeen million people…

The study of microbiology requires not only understanding the microscopic organisms, but also the understanding of lab techniques and procedures used to identify, control, and manipulate microorganisms. The identification of microorganisms is not only important in microbiology lab, but also in the medical field to identify an agent of a disease that will help treat the patient by using the correct antibiotics to kill off the host. In this unknown lab report, techniques and procedures learned in…

The general term “microbes,” is used to describe any organism that cannot be seen by the human eye. While individual microbes cannot be seen, these microorganisms usually form colonies in which their species can be observed and categorized. In this experiment, the effect of environmental selection on biodiversity are measured and compared in two locations. The inside of an air vent and the top of a cabinet were passed over with cotton swabs, which were then used to streak agar plates to…

In the Disney animated classic, “Beauty and the Beast”, there is a scene where Gaston is talking to Belle and he takes her book away and says to her, “It’s not right for a woman to read. Soon she starts getting ideas…and thinking..” Gaston saying this wasn’t even the part that is wrong with the entire picture; it’s the fact that the entire village agrees with him because women reading was not something women should be doing back in that day. Women were seen as cookers, cleaners, and the ones who…

Invasive Species An invasive species is one that is not native to a particular ecosystem and that does or is likely to cause harm to the environment and/or the economy (Exotic Species in Illinois). For example, a Multiflora Rose (Rosa multiflora). This rose, also known as the baby rose, it is native to eastern Asia, and was introduced to the U.S. in the late 1700’s. The baby rose impacts an environment, by forming dense thickets that invade pastures, and crowd native species (Plants). Invasive…

Ever since life first roamed the Earth, any living beings with a working mind had made decisions. Choices, if you will, that are made for one’s own benefit. The fact of the matter is that it is purely instinct to place oneself before others. Instinct is the driving force; the core motivation to a being’s actions. Through a plethora of circumstances, instinct can be perceived as either good or evil; it has easily shaped itself into words as powerful as greed or intelligence. Right from birth and…
