How Does Caffeine Affect Plant Growth
My hypothesis that the lima beans watered with the coffee mixture would grow the fastest was proven true. Using grounded coffee in other plants is a common practice to make plants grow faster. However, coffee also contains other ingredients like potassium, which are known to improve plant growth. Experiments on plant growth using only caffeine have resulted in the plant leaves becoming wrinkled, turning brownish and exhibiting stunted growth.

    The purpose of this lab was to explore the growth and developmental differences in different liquids when exposed to a lima bean over the course of 10 days. by looking at the results it is evidence that the pond water is the greatest factor of liquids compared to milk and sprite. My hypothesis of pond water being the best liquid to grow a lima bean plant was correct the lima bean had grown to 13 centimeters but while doing this experiment I was surprised with the results of milk hoping it to be better and hoping for more growth due to its nutrient content before completing this lab I had the impression that milk would be the second most growth in the plants due to it protein and nutrient content. But I believe that these results were not…

    Caffeine is a bitter, white crystalline xanthine alkaloid that is a psychoactive stimulant drug. Caffeine is found in varying quantities in the beans, leaves, and fruit of some plants, where it acts as a natural pesticide that paralyzes and kills certain insects feeding on the plants. It is most commonly consumed by humans in infusions extracted from the cherries of the coffee plant and the leaves of the tea bush, as well as from various foods and drinks containing products derived from the kola nut. In humans, caffeine has a stimulant effect, causing increased amounts of stimulatory neurotransmitters to be released. If the consumption of caffeine is…

It is found most commonly in cocoa, tea and coffee, but is also artificially added to some soft drinks such as cola to act as a flavour enhancer.

    Lima Bean Experiment

    The lima beans with more calcium added also germinated quicker than the ones with minimal amounts or no calcium at all. The data recorded supports the hypothesis that if calcium is added in greater amounts, that the lima beans will grow taller and healthier. The plants in groups 4 and 5 grew much quicker and faster than all 3 of the other groups. The lima beans in groups 4 and 5 germinated in the second day while the 3 other groups took 3 days to germinate and sprout. The total amount each plant grew in the different groups is directly correlated with the amount of calcium added to each group of plants because certain variables were kept constant to ensure that each plant had the same environment. The benefits of calcium in plant growth are numerous. Calcium helps in the metabolic uptake of nutrients vital to plant growth. It also helps in creating a strong cell wall and membrane in the plant’s cells which help in fighting against diseases and fungi’s. For these reasons and more, that is why calcium plays such a big role in plant growth. The results are noticeably different and show clearly that calcium aids in lima bean growth. A few flaws in my experiments design were that the scale was not a .001 accuracy scale which means that the amount of calcium added could have been less accurate than possible. Also since the plants were…

    The amount of water for growing a plant has always been questioned regarding how much of it is most effective to grow the plant to its greatest potential. Too little water will not effectively grow the seed because it would require more water for photosynthesis. If there is not enough water, photosynthesis will not occur as much and will not produce as much C6H12O6 (sugar) it needs to construct cellulose for its cell walls (its structure), produce ATP (energy) molecules from respiration, and make organic molecules. Too much water would also be dangerous for the plant because oxygen wouldn 't be able to get through the overwatered soil and get to the roots, thus suffocating them. Oxygen is vital for respiration, the process of making energy (ATP) for the plant. Also, overwatering can kill the seed by drowning it and making its tissue fragile to rotting, not even growing the plant. From these researched observations, it can be assumed that the in-between amounts of water are favorable to the growth of the seed and plant lifespan.…

    I found out in an article by Mary Gavin that in fact coffee or caffeinated drinks do not stunt growth but in fact it stimulates the central nervous system which can lead to growth stunt but very rarely does it. Caffeinated drinks also have some short and long term affects to it. Speaking short term effects, caffeine starts affected your body after an hour on an empty stomach and last usually 4-6 hours. Since caffeine acts as a stimulate, most people in these few hours experience increased alertness, blood pressure, and breathing rate. Caffeine also leads to increased urination which can lead to dehydration. There are also a few long term effects which include nervousness, insomnia, stomach irritation, and fatigue. (Trustees of Princeton,1) All of these effects are not periment and all depend on the amount of coffee a person…
