Effec | Effect of caffeine on plant growth | Description This science fair project was performed to find out the effect on plant growth of adding caffeine to the soil. The experiment was done by using mung bean plants and watering them daily with water, water mixed with caffeine and with a coffee mixture. Hypothesis The mung beans watered using the coffee mixture will grow the fastest. Overview Caffeine and plant growth The effect of adding caffeine to the soil and its effect on plant growth
the three plants. The special feature of the fruit is the particularly high content of caffeine that coffee can no longer compete. Guarana is actually a vine plant and loves the tropical and subtropical climate. Guarana is not a tree but more like a shrub which can be up to 15 meters high. Especially as a young plant, the branches are lignified, hairy, soft and Brown. As the plant becomes older, the more the branches are softer, so they remind of lianas. The leaves of the plant are about
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
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
Caffeine is a plants toxic defense mechanism that is commonly consumed by humans. This caffeine is located in the nectar of plants and is use to prevent herbivores from eating the plant. In this study they observed two caffeine producing plants, Citrus and Coffea in order to provide evidence that the caffeine compound alters pollinator behavior by enhancing their memory due to this “caffeinated award”. They had measured caffeine in nectar of three species of Coffea (C.canephora, C.arabica and C
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
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
Abstract: The experiment was conducted by a number of individuals to see how the effects of a substance would have an effect on a Daphnia. The Daphnia’s were placed in multiple different substances environment to see the effect it would have on their heart rates. When doing the experiment the first step was to take the Daphnia and put it a Water solution to observe the heart rate of the Daphnia and record the heart rate. Recording of the heart rate were taken for when the Daphnia were in the Water

The partial charges throughout caffeine molecules create dipoles, which in turn affect the intermolecular forces between caffeine molecules. Caffeine’s polarity permits the formation of dipole-dipole interactions between two caffeine molecules. The partial positive end of one caffeine molecule will be attracted to the partial negative end of another caffeine molecule, creating a relatively strong intermolecular force. The strength of this force will increase sublimation and melting points and decrease
