How Does Caffeine Affect Plants

Introduction
It seems that in our day and age humans rely on caffeine for many things from that morning cup of coffee, soda with popcorn, caffeine infused skin products and many other applications. Our premises are that if caffeine can help with our skin and energy boost then wouldn’t the same apply to plants? The goal of this biology project is to examine the effect of caffeine on plant growth. Caffeine comes from a plant so it would seem that it could help plant growth. A plausible prediction is caffeine will support plant growth by providing a source of nitrogen or carbon dioxide through its the catabolic breakdown. Could the use of caffeine aid in accelerating and benefit the plant growth?
Method
To test our hypothesis, we set
We measured the plants everyday (possible) that we were in the lab, which ended up being for a period of four weeks. The quantitative observations were height measured in inches and is portrayed in the included data (Figure 2).
The overall health of the plants that received treatment appeared marginally more deteriorated: stems appear a diminutive in proportion to the control plant. The petioles of the higher concentrations seem shorter. Each plant was removed from its soil and root structure was observed. Upon observation of the roots we noticed a substantial difference in the health as well as the fact that the roots of the plants receiving caffeine. The caffeinated plant roots were markedly smaller and thinner than that of the control plant. A sample of each of the plant roots was obtained from both the uppermost root to the tip for scrutiny under a microscope. The slides were stained prior to observation. The objective was to view cellular structure and see if any significant differences could be seen. On all three slide we were unable to see any cellular differences or damages. We were unable to proceed further, as more sensitive equipment would have been required and was not
