Recommended: Research essay on soil ph and plant growth

In my hypothesis I previously believed that the lower the lower the pH level the more seeds would germinate, due to the extra hydroxide. But more seeds actually germinated in the pHs closer to neutral. Some problems in the experiment was the towel drying out and the seeds no longer absorbing the pH, rewetting the towels with the solution could prevent this. Some experimenter errors that occurred is the seeds falling out of the towel which resulted in seeds germinating or not germinating. Also, air getting into the bags and drying out the towel faster could have been prevented by making sure the bag was closed. Lastly, the seeds did not get put in the bag exactly like the previous time which could have affected the germination. To improve this lab, measuring out the same amount of solution for each pH could have made it more accurate. To further this experiment we could have had another set of seeds in the same pH solutions but in the sun to see …show more content…

Also, on the second day we observed that the seed in pH 5 was turning to a lighter color compared to the other seeds which stayed the same. Then again on day 5 pH 5 seedling stem was more white compared to the others which were more green. Lastly, in all of the different pHs at least 3 seeds germinated from each one. The differences in all of the solutions was the pH, the lower the pH the hydroxide the solution had but the higher the pH was the closer it was to neutral. The results of our experiment varied from solution to solution, but the closer the pH was to neutral the longer the seedling was. The control group in the lab were the seeds that were not soaked in any solution because the control group has nothing done to it, and the experimental group was the seeds in the

    One thing I could have done to improve my experiment was to have used a more secure lid on the growth tray to have ensured that all moisture would have stayed in the appropriate area. This makes me less confident about my data because there is a possibility that it could have disrupted the moisture levels in the soil and could have minorly diluted or concentrated

    An example of this was with some seeds not growing. I felt like our error was that we over watered our seeds, causing some of them to drown, and to not grow properly. In order to fix this error in future experiments, we would need to drop the water within a flask to measure it, or to have a set amount of water to give to the seeds. Another error present in our experiment was improper spacing of the seedlings. In our experiment, our seedlings were very close to each other, and they were probably too close to grow out a stem. In order to fix this, it would be better to place seedlings within the petri dish one by one or a couple at a time. This would reduce the clumping of seeds, and could allow seedlings to grow their stem properly instead of getting stuck in a small place. A couple ideas for further experiments could be to see how far an albino seed can grow in light conditions. Since they have no chlorophyll present, I feel like it would be interesting to see if it would even grow properly since it can't go through photosynthesis. To add on to that, another experiment test if the seed with chlorophyll grows faster since it goes through photosynthesis. It could test to see if photosynthesis really speeds up the growth of a

  • Compare And Contrast The Levels Of Non-Germinating Seeds And Crickets

    220 Words  | 1 Pages

    The graphs helped show the levels of oxygen and carbon dioxide in the bottle when it came to testing germinating seeds, non-germinating seeds, and crickets. For the germinating seeds, the oxygen levels were rising and the level of carbon dioxide was slowly rising. This relationship shows that the germinating seeds were in the process of cellular respiration. The O2 is a product of the germinating seed while water and oxygen are the reactants needed to start respiration and make ATP. The non-germinating seeds, however, didn't show any drastic change in O2 or CO2 levels, when it came to the graphs. The reason why this occurred was because non-germinating seeds aren't growing, but are rather dormant. However, very little oxygen was being used,

    We then proceeded to construct a device to measure the amount of oxygen used for each of these 6 groups. To do this we acquired 6 vials which were waited with a metal washed on the base. At the bottom of each vial, we placed an absorbent cotton ball which contained a few drops of KOH. KOH, also known as potassium hydroxide which absorbs carbon dioxide. e then placed a non absorbent cotton ball on top of the absorbent cotton ball in each of the vials. Each of our separated groups were then placed in a vial, one per group. All of the vials were finally topped of with a rubber stopper and a pipette which ran through the stopper. The pipette contain units of measurements in mL which show how much oxygen was lost by looking at the water moving towards the organisms in the vial. This device is called a respirator. We then filled out two black trays with water. One contained normal room-temperature water and the other contained ice water. Paper towels were then placed at the bottom of the tray to increase visibility of the markings on the pipette. Then one vial from each of the pairs created were placed into the room temperature water. These vials contained beads, beans and dry beads, and germinating beads. Water would then enter the pipette and would be recorded when its advance towards the vial significantly stopped. Each of the vials measures were then recorded every 4 minutes until 16 minutes had passed from the start of the vials submergence The same was performed with the vials not yet submerged, but they were placed in cold water. We then compared and analysed the data with each other and our expectations and drew a conclusion using this new

    Two members of the group were instructed to visit the laboratory each day of the experiment to water and measure the plants (Handout 1). The measurements that were preformed were to be precise and accurate by the group by organizing a standardized way to measure the plants. The plants were measured from the level of the soil, which was flat throughout all the cups, to the tip of the apical meristems. The leaves were not considered. The watering of the plants took place nearly everyday, except for the times the lab was closed. Respective of cup label, the appropriate drop of solution was added to the plant, at the very tip of the apical meristems.

    We used wheatgrass were 40 wheatgrass seeds, two empty pots, soil, and water. We first added soil for both pots and 20 wheatgrass seeds in each pot. My partner and I decided that we label pot one experiment which is “sugar and water” and pot two control which is “water” only. The experiment was for almost four weeks we had to make sure both get the same room temperature and water, so we can see the results after this amount of time. Both pots had same room temperature so both can have the same amount of sunlight also, the same amount of water which is a glass of water from the sink once a week. In the experiment pot we added a glass of water with one teaspoon of sugar and the control pot glass of water. Every week we used to see both pots grow almost the same. At the end of the experiment, my partner and I measured the length for both plants and we recorded the average for each plant, so we can know the rate of growth

    Yes the hypothesis was supposed, which was "Germinating seed would take in more oxygen because they are actively going through cellular respond growing. This is shown in the data when looking at the Corrected Difference at 5 minutes germinating peas was at .05 and dry peas with beads was only .01, then looking at the data at the end at 20 minutes germinating peas were at .24 and dry peas and beads were at .04. The germinating were ahead of the dry peas with taking in more oxygen. The independent variable was the germination of the peas. The dependent variable was the amount of oxygen consumption. Germinating peas are growing and going through cellular respiration at a higher rate, this effects oxygen consumption because because the higher the

  • Watermelons

    In seedless watermelons, rudimentary seed structures form but remain small, soft, white, tasteless and undeveloped tiny seed coats that are eaten virtually undetected along with the flesh of the melon. Seed production for these seedless types is an extremely labor intensive process that makes the seeds relatively expensive. Because germination of these types is often less vigorous than normal types, it is recommended that they be started in peat pots or other transplantable containers. Here the germinating conditions can be closely controlled. Once transplanted, cultivation is similar to that for regular watermelons.

    These seeds were germinated for around five to ten days, depending on the conditions applied. The reasoning behind the germination conditions is not fully explained. After germination, all parts of the plant, including the germinated seeds, cotyledons, plumules, hypocotyls and radicles were separated from one another to be tested. The main methods used for this study were ELISA and Western blot analysis.

  • Examples Of Seed Dispersal Lab

    The data for this lab was taken from Table 1. The highest time that was recorded for the glider method was only 4.10 seconds, and the longest distance traveled for the seed was 283 centimeters. Looking at Figure 1, time varied from 2.41 seconds to 4.10 seconds which indicates that 100% of the data for time was greater than the control group but less than five seconds. It can be inferred that using the glider method for seed dispersal increases the time taken for the seed to reach the ground. It can also be inferred that a different design for the glider could have made it possible to reach five seconds. According to Figure 2, there was a great variation in distance, ranging from 27 centimeters from the starting point to 283 centimeters. The variation shows the importance of the variance of the landing spots of the seeds in nature, because if all the seeds landed the same distance away from the point of origin, less seeds would have a chance of growing in a habitable area. About 30.4% of the trials had a greater distance traveled than the control group. A possible reason for the low amount of trials that surpassed the control group in distance was the lack of wind because of the tests being indoors. Also, wind could increase the time that the glider stays in the air, which
