Controlled Group Height Lab Report

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

The hypothesis behind this experiment is that the Gibberellic acid has a positive growth effect on the plant and causes it grow larger in height.

The ravg for the experimental group was 0.1613 and the ravg for the control group was 0.2047. The results indicated that our predictions were correct; duckweed that received less light exhibited a lower rate of

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.

4.    After 5 days, measure the height of the 10 plants in each pot. Add up the individual heights and divide by 10 to obtain the average height. Record the average heights in a table, as shown below.

Throughout this experiment, we are researching the effect on the growth and survival of Wisconsin Fast Plants using fertilizer pellets to help with the growth of the plants. Wisconsin Fast Plants is a plant member of the crucifer family which is related to other plants (vegetables) such as cabbage, broccoli, turnips, etc. This plants are small and can grow very easily because they go through their cell cycle around 40 days. Wisconsin Fast Plants Fertilizers are different materials used that can provide plants with the nutrients it need to grow. (1) These plants are a good model system to study because they grew very quickly and didn’t need a lot of resources to grow making them the perfect plant to use for studies. (4) By using the fertilizers,

This experiment began on the first day of lab by planting 12 total seeds from the F1 generation in six individual cells. Potting soil was added until each cell was a little

A reason as of why the experimental group grew taller would be that maybe the seeds in the control group did not get as much water as the experimental group did. Although there was a controlled amount of water put in each petri dish, there was an extra layer of paper towel on top of the seeds in the control group dish that could have soaked up more water than the experimental group. This factor could deprive the seeds of necessary water, therefore making the seed germination process much harder and could take longer. Also, there was one seed in the control group that did not germinate at all. The water could possibly not have reached that seed in particular. The water was most likely absorbed in the paper towels or other seeds before it even reached that seed in particular.

What water level did you select for plant growth during your first attempt? Describe the observations of your plants at this water level. Based on your data, was the level you picked the best choice for optimum

The number of dwarf plants recorded from a class average was 44, and the number of tall plants recorded was 48 as shown in figure 2. Using chi-square analysis can help determine if the results are valid to either accept or reject the hypothesis. The equation used to determine if the hypothesis is accepted is:

The first experiment was supposed to determine which cell fraction had the most

Throughout the experiment the experimental was rejected and the control was the successful on that made progress. The fact that I predicted that it good to use this made me wonder what, we could have done a little better to make both plants grow in the same length. The data that was collected was different because, everyone in the classroom had a unique way for their experimental plant which I saw (lemons, propel water) and in one of the groups plant grew mole. Which was gross but again each group had their way of experimenting with varied materials. The results were different because one of the groups in the afternoon class plants grew fast.

The aim of this practical was to test whether a Scarlet Globe Radish will grow higher in cm when watered using different types of water and the hypothesis was that scarlet globe radishes should grow higher when watered with sparkling water as it contains co2 however that hypothesis was proven incorrect. From results it can now be concluded that the control patch surprisingly produced the highest plants in terms of height with an average ground to leaf height of 2.2 cm while the sparkling water patch produced 1.86cm and the filtered water patch with an average height of 1.18. However, from research it was shown that sparkling water was more likely to make radishes grow at a faster rate. A faster growth rate would’ve made the radishes taller

According to a study, an experiment was done over the course of six years on the growth, needle, carbon, and nitrogen, chlorophyll, and

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
