The Statement Of Purpose Of The Bean Plant Experiment

In this experiment we are testing the effect of fertilizer on the speed of plant growth. We prepared a 4 quad cell, 1 control group and 3 experimental groups. So, we had one with no fertilizer, one with three seeds of fertilizer, one with six seeds of fertilizer, and lastly, one with nine seeds of fertilizer. The plants that we grew were called Wisconsin Fast Plants, members of the crucifer family. These plants are small and easy to grow, but for optimal growth they require continuous fertilizer, water, fluorescent light, and temperature between 18 degrees Celsius and 26 degrees Celsius 24 hours a day. Fertilizers are substances that are put into soils to increase the growth of the plant. There are two different types of fertilizers, synthetic

Four cups of equal size were filled with one cup of garden soil. Lima beans were planted at an equal depth (one inch as instructed on the bag). Every day, for 33 days, each plant received one half tablespoon of the specified liquid. Beans one and two got one half tablespoon of water each,

In the dishes, I dropped the appropriate treatment into the center, where the marks were made. Next, I closed the petri dishes, taped them up, and let them sit at room temperature for a week. Then I opened them up to take two measurements. The first measurement was the number of seeds germinated. The second measurement was to measure the seedling lengths.

Two treatment groups were covered with a screen in order to reduce light intensity. Both groups were kept under a controlled light source for fourteen days and plant counts were taken at regular intervals.

Introduction: Photosynthesis can be defined as a solar powered process that removes atmospheric carbon dioxide and transforms it into oxygen and carbohydrates (Harris-Haller 2014). Photosynthesis can be considered to be the most important biochemical process on Earth because it helps plants to grow its roots, leaves, and fruits, and plants serve as autotrophs which are crucial to the food chain on earth. Several factors determine the process of photosynthesis. Light is one these factors and is the main subject of this experiment. The intensity of light is a property of light that is important for photosynthesis to occur. Brighter light causes more light to touch the surface of the plant which increases the rate of photosynthesis (Speer 1997). This is why there is a tendency of higher rates of photosynthesis in climates with a lot of sunlight than areas that primarily do not get as much sunlight. Light wavelength is also a property of

The first lab was conducted to analyze how germination affects the rate of cellular respiration in lima beans compared to dormant seeds. In order to

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.

After finishing the entire lab experiment, I find that those were the only big problems I had. If I were to improve this experiment, though, I would find a good window ledge, buy a tape measure and have a better object to block the experimental seeds from the sun. Other than these factors, I feel this lab went very successfully and that the results were reasonably accurate.

First, before starting my experiment I did some research on the growth of lima beans, so that I could start the base of the project. According to research done at the University of

The purpose of this lab was to investigate and observe the effects of organic vs. synthetic fertilizers on plant growth by planting lima beans with added amounts of fertilizers, and to see how does adding different nutrients to the soil affect the growth of the lima bean? A significant difference was examined between the plants that contained manure and miracle growth, unfortunately the plant with no additional fertilizers (Plant #3) did not show any growth. The plant that grew the most was the one that contained manure, to an extent the one that grew the most in a short period of time was the one that contained miracle growth, as shown in figure I. The hypothesis explaining if the Lima Bean plant contains synthetic nutrients in the soil then

Take the bowl of water and the paper towels. Submerge your hand in the water, then pat the paper towel with your hand, to dampen the towels before planting but not to the point where the towels are soaked. Do this for each group of seeds soaked in the solutions (5).

While experimenting with the green beans, the seeds exposed to the organic plant food germinated within five days of the experiment and the seeds exposed to the chemical plant food germinated within six. The seeds that acted as the control had been expected to grow the least, however, it was surprising that they did not grow at all. Both the chemical and organic fertilizers proved to have positive results on the plants. It was also unexpected when the seeds exposed to the chemical plant food surpassed the height of the other experimental seeds after being shorter. The predicted reason for the increase in growth with seeds given Miracle Grow was because chemical fertilizers automatically store up the nutrients and disperse it constantly throughout

The third step that was taken was germinating the seeds. Two sets of paper towels were used to germinate the

In fact, it was Plant E which only received indirect sunlight. Plant A, by day twenty, had only grown to twelve and one-fourth of an inch whereas Plant B had grown to seventeen inches. Throughout most of the experiment, Plant A was never the tallest plant except for day(s) four and six. I believe the reason for this is due to the fact that since Plant A had a constant rate of light, it processed way too much energy for it to be a healthy intake. Therefore, my hypothesis was proven

At the beginning of this lab my group and I were instructed to go and cut 24 10cm coleus plants. After we had done so we put three in a 2½ pot making eight pots total, we then filled each pot with a clay media. After that we then labeled each pot assigning two pots to four different treatments. The first treatment was for the plants to receive fertilizer and heat, the second was no fertilizer with heat, third was fertilizer without heat, lastly to neither be given fertilizer nor heat. We left the plants to taken care of by the greenhouse manager Bronson, with the instruction to come in and take observations of the pant to make sure they are doing well.
