The Effect of Caffeine on Plant Growth

Add three seeds to the potting mix and cover seeds with little remaining potting mix. After the addition of the potting mix, use a dropper filled with water and water each cell until water drips from the wick. Then place the quads on a watering tray under the fluorescent light bank. Each cell should have an equal distance from the light bank. Quads should be three inches below the fluorescent light; the light should also be left on all day. Make sure all wicks are in contact with the mat that sits on the watering tray. Also watch out for the watering system regularly throughout the experiment. After four to five days record plants in the quads, giving their phenotypes in a table for each cell removed all but the strongest plant.

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 biological process in plants. Caffeine may increase the pH level in the soil which may be toxic to some plants because of the acidity in the soil. Caffeine may also keep insects off the plants. (Grant, 2016)

The purpose of this research is to find out how nutrients, such as phosphorus and nitrogen affect plant growth. To find out how the plants are affected by growth in the different nutrient treatments. With the results found, what does this suggest about how people should fertilize the soil in which people grow food crops. Using the species of grass rye, the research investigates the effect of the absence of nitrogen and phosphorus.

Question- Do Lima beans grow faster when they are watered with sugar water rather than tap water?

In my experiment, I needed to have five tomato plants that were all roughly the same size. I also needed five different liquids to water them with; I chose to use soda, salt water, tap water, carbonated water, and river water. I then needed five different pots each with

Have you ever wondered how energy drinks, acidic juices and water affect plant growth rates? You’ve probably never wondered about that because it is not that common. So get ready to learn!

Coffee has an effect on more than just the brain, caffeine also affects a person calcium level. Calcium is good for a person’s bones and teeth. Calcium is used tom send signals between neighbouring molecules. Caffeine may trigger the plants to release a lot of calcium inside themselves and this could have a major effect on the growth of a plant.

The figure 5 represents the wet weight from the control and experimental groups. The data shows that cabbages weigh more than onions for pot #3 and #4. For pots #2 and #5, tomatoes weigh more than cabbages. For the control groups, 4 cabbages (pot #2) weigh more than 8 cabbages (pot #6).

The effects of caffeine, especially caffeinated coffee, on human performance have been widely studied. Another study has been conducted to

Hypothesis: My hypothesis is that plants will grow faster with a higher amount of caffeine.

INTRODUCTION In this experiment, a combination of solid/liquid extraction and liquid/liquid extraction will be used to extract caffeine from tea leaves. After “crude” caffeine is obtained, the caffeine will then be purified through the process of sublimation. DATA AND CALCULATIONS MASS OF CRUDE CAFFEINE: ______0.0189g______________ APPEARANCE OF CRUDE CAFFEINE (color, etc.): ____forest/olive dark green color, slightly yellow_______________ MELTING POINT OF CRUDE CAFFEINE: ___171.8° C-209°C____________ MASS OF SUBLIMATED CAFFEINE: ____0.0073g_____________________ APPEARANCE OF SUBLIMATED CAFFEINE (color, etc.): __on centrifuge “cold finger”: dark brown color, not dry powder_________ __in flask: off-white color, dry powder, more

Coffee does not actually slow down the growing process. Caffeine stimulates the nervous system. There are actually many vitamins in coffee that help cellular growth.

However, we wondered how fast it would take place over the course of seven days. We eventually came to the conclusion that coffee had the stimulant of caffeine within it and could possible stunt the growth of the duckweeds. Then on Day 3, we noticed a trend: the plants were growing roots, which was a good sign as they continued to do so until the end. We also noticed the unexpected color and mixture of the coffee changing within in each beaker. The coffee began to turn green and murky, a oily film even began to develop over the top of it. As the days increased our group took notice of the dissolved plants within bigger concentrations. On Day 5, we then began to notice a few unexpected dead duckweeds in higher toxicity levels. We discussed and reasoned since coffee includes many different ingredients, such as; potassium and phosphorus the duckweeds would increase in growth (Caffeine Informer Staff, 2017). Many of the duckweeds formed roots and began to expand in size which was a result of the coffee mixture. We also realized caffeine is a chemical stimulant and can enhance the biological process not only in humans but in plants at a stable rater: however, it can also kill plants due to the increase in acidity, which is toxic to the plants. When humans have caffeine it stimulates our central nervous system but due to the ingredients within it, it has a similar yet

The study “Caffeine levels and Plant Mortality” explains how caffeine can affect plant mortality during germination. In the study, high doses of caffeine reacted with the plants causing plant death. In the article scientists

This same substance makes the used coffee grounds an excellent fertilizer. If you mix used coffee ground with the soil you are going to use for planting, you will speed up the growth of the microbes in the soil. The nitrogen will provide the plant with nutrients as well.
