The Effect of Caffeine on Plant Growth

the Greek language; Allele means two sided harm, and pathy means suffering (Willis, 2010). The release of chemicals by one plant that can affect the growth of another plant is called allelopathy (Ferguson, 2003). The chemicals released from a plant which possess allelopathic influences are termed allelochemicals or allelochemics (Johnson J, 2012). Different parts of a plant can secret allelochemicals. They can also be released naturally (Cipollini, 2012). They can be found in leaves, pollens, roots

Is Caffeine good or bad for living organisms? This is a topic that has been debated all around the world. Plants are essential to life on earth because of their ability to make food. They make food by using a process called photosynthesis. Some plants can also produce caffeine on their own. Caffeine speeds up regeneration in Planaria. Caffeine is used to stimulate the central nervous system. Caffeine is consumed in large quantities daily, but it can have both positive and negative effects on living

Caffeine is the most used drug in the world. Caffeine is used to fuel the human body, making people feel more awake and energetic. This addictive drug was discovered in 1819 by a man named Friedlieb Runge. Friedlieb found this substance while examining mocha beans. Caffeine can make people more awake, alert, and able to concentrate. Throughout the day, a chemical called adenosine builds up in the human body. The nervous system has special receptors to monitor adenosine levels. As the day goes on

Plant compounds play a very important role in the defense of plants and in this experiment the plant defense compounds of caffeine and Kava-kava were tested on Daphnia magna to test if there was a change in heartbeat of the organism. The purpose of the experiment was to see how these compounds affected the Daphnia magna. The t-values for both the caffeine and Kava-kava were calculated to be 1.82 and 1.62, which were both smaller than the obtained t-critical value of 2.57. A conclusion was drawn

trimethylxanthine, better known as caffeine is defined as a drug or a stimulant compound found in coffee, tea and cocoa naturally (Dash, 2008). Caffeine is an alkaloid, which is a substance that is produced as end products of nitrogen metabolism in some plants. Caffeine can also be found added to soft drinks and medicine. The consumption of caffeine has several effects on the human body. One of the most important effects is the inhibition of phosphodiesterase. It has been reported that caffeine can be considered

All plants have caffeine enzymes. These enzymes are members of N-methyltransferases. When leaves drop off plants that contain caffeine, this will fertilize the soil with caffeine. (Grant, 2016) The amount of caffeine that the soil is contaminated with will determine the growth of the plant. Too much caffeine in the soil may have a bad effect on the plants growth and structure. Caffeine affects the ability for plants to photosynthesize and collect it’s nutrients. (Grant, 2016) Caffeine increases the

article talks about how caffeine works and how it may be considered a drug. The article starts out by saying that billions of people are addicted to caffeine and then explains the history of caffeine. It was originally used to protect against insects because the amount of caffeine in plants is toxic to bugs. Then, when the caffeine was absorbed into nearby soil, the plant growth of nearby plants would be hindered. Because of this more and more plants evolved to contain caffeine and eventually it was

Christian O. Zipagang, Lance Harvey O. PROBLEM: How Caffeine affects a Gold-fish Chapter 1: The Problem and Its Background * Background of the Study * Caffeine is becoming a common chemical found in the environment but, little research has been done to understand the environmental effects of caffeine, including dissolved caffeine in aquatic systems. The goal of this research study was to begin to understand how caffeine may interact with aquatic

Biology HL How Does the Presence of Caffeine Affect the Growth of Bacteria of the Digestive System? Student Name: Bixiang (Sean) Cheng Session Number: 000537-0010 Supervisor: Ms Julie Cavell Word Count: 4000   Abstract Caffeine is the most widely consumed legal psychoactive drug across the world. It is widely used to ward off fatigue and increase focus. Although it is considered to be a harmless substance, and sometimes beneficial, it has been shown that caffeine has antibiotic properties against
