A Lab Report On Plant Growth And Growth

Observing the Wisconsin Fast-Plants was a monitoring experiment, we were just observers to the natural life cycle of these plants, and we did not influence their growth in any way that would not occur naturally. We took notes and observations about each stage of

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

All five groups recorded the outcomes that they established. For our bench, we found that nine raddish seeds in the control dish, zero raddish seeds in the eucalyptus dish, and four radish seeds in the lemon dish germinated and sprouted. Our bench also found that the average seed length for the control was thirty one millimeters, for the Eucalyptus was zero. and for the Lemon was eight and a half. Below, is a chart and graph that shows the whole data as averages from all five benches. Each bench did the exact same experiment so we knew nothing would be biased.

Cotton, first domesticated in 2300-1760 B.C.E had been domesticated and heavily cultivated and manufactured into textiles for export (dying techniques had become prominent as

The results observed do not correspond with the outcome predicted by the hypothesis. Despite the nature of the subjects of the experiments, no substantial growth was observed. Only one seed of the 36 planted germinated, and it could only survive for a period of a week. The one seed that germinated reach a height of 1.2 cm. Table 1 presents the average growth observed in each quad. Each quad had a total of 12 seeds. No seeds were removed during the course of the experiment.

“ There are your radish seeds everyone.” Said Mr. Susick. The whole class looked around at each other with a blank confused face. It was the first day of junior year in my English class. Mr. Susick started talking about how our first assignment would be to grow radishes. We were all thinking, how in the world does gardening relate to English class. I had heard about this project from previous juniors but none of them said what the real reason was. All Mr. Susick said was that you need to let the project teach itself and get into nature. He left us with one bit of information along with the requirements to start. The main goal of the assignment was to extract your own universal truths. For the first time in English class,

There was no money crop whatsoever; the only variety of cotton that would grow in that region was the practically useless green seed variety. Ten hours of manual work was needed to separate one point of lint from three pounds of the small tough seeds. Until some kind of machine could be built to do the work, the green seed cotton was little better than a weed.

This experiment, which was used to explore the Theory of Evolution created by Charles Darwin. The use of natural selection was apparent in the artificial modification of an organism's traits which aided in this investigation. Through this experiment the Wisconsin Fast Plant was used. It is a fast-growing organism developed to improve the resistance to disease in cruciferous plants. This plant aids scientist in the exploration of environmental effects on population due to the speed to which is matures and reproduces. Artificial selection was stimulated by the selection against plants with few hairs(trichomes). Trichomes create a wider variation which means it is polygenic. The plants that had only a few trichomes were

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.

The low-density radish-collard mix pots contained four seeds of radishes and four seeds of collards. The high-density radish-collard pots contained 32 seeds of each species. While our group replicated this 3x2 design four times to total 24 posts, we incorporated the whole class data. Therefore, there were 16 replicates for each treatment. For each pot, we filled soil up until about one inch from the top. We placed the seeds in the pot and piled on around 2 or 3 cm of soil on top. In 3 species levels, seeds were spaced as evenly as possible. In the mixed species pot, the two species were alternated so that each one had the same access to space and nutrients at the other. For each pot, we wrote down our section number, group name, and the contents of the pot. Our group worked at the first bench in the greenhouse and also contained our pots that were spread out evenly in four rows. Our pots stayed in the greenhouse for about five weeks, captured as much sunlight as they could, and got their water source from sprinklers that automatically came on twice a

After gaining some knowledge about bacteria, we were giving an investigating bacteria growth lab to do. Our objective was to observe the conditions required for bacteria to grow and to test the effectiveness of substances that may be antibacterial, disinfecting, and or sanitizing. My group and I began our procedure by gathering all the bacteria by swabbing our necks and mouths. After this, we inoculated the culture by rubbing the bacteria on the agar, a nutrient rich gel made from sea kelp, on the bottom side of the container where we grow bacteria, the Petridish. We hoped for the results to come back with little or even no colonies and an immense zone of inhibition around the tiny circle cut out of filter paper covered in toothpaste, Neosporin, and Chlorhexidine Gluconate 4% Solution.

5. Weighing: Drag each ear on each of the plants to the weighing dishes to weigh its kernels. The yield of kernels of each plant is now on a weighing dish. Drag a weighing dish to the balance to read the weight of the kernels. Record the weigh of a Data Table. Proceed to weigh the kernel yield from all plants. Calculate the average kernel yield form each set of three identical plants that are grown under identical conditions from the same type of seed. Record the calculations on the Data Table.

This experiment is about bacterial growth. We will demonstrate a bacterial growth curve using a closed system. Bacterial growth usually takes up to 12-24 hours to get an accurate result so we will be monitoring this growth between two classes. We also used different methods to determine bacterial growth as well as a few different calculations. One way of receiving data is by using a spectrophotometer where we will record the absorption at a given time to create the bacterial growth curve. We also used the plate count method after performing a serial dilution to calculate the actual cell density at different times given. By using this method we can count the population number of the same given and see the maximum cell density

Cotton is the shortest commercial textile fiber. The cotton plant that is grown commercially grows to a height of about 1.2 meters. The cotton plant is fairly drought tolerant, though it requires a regular and adequate moisture supply to produce profitable yields. Cotton is grown in over 90 countries over the world, out of this 90 countries, 75 of them are developing countries. Although cotton is grown in both hemispheres, a higher percentage of cotton is cultivated in the Northern hemisphere. The times for harvesting and planting cotton are reversed in both hemispheres i.e. when it is the time of planting cotton in the Northern hemisphere, it is time to harvest cotton in the Southern hemisphere. Cotton is mostly cultivated between 37º N and 32 º S; however, its cultivation has been extended to 45 º N in China. US paper currency isn't paper at all; it is a blend of 75% cotton lint and 25% linen.
