However, for each quad, the fertilizer used for the control was added altogether with the fertilizers being studied. Since the only plant that presented growth was in the control quad, it becomes necessary to explore the effects of excess fertilizers, and furthermore, excess nitrogen, would have in the development of the fast plants. Although Nitrogen is one of the elements most living organisms require, some studies have showed high levels of nitrogen can cause toxic stress to some plants, to the point where growth can be inhibited. (Yu et al.

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,

Gatorade is less helpful than water at making plants grow. The sugar causes a build-up of mold and thickens the soil to the point where the plants cannot grow very well. The 200 milligrams of salt in Gatorade also inhibits plant growth by preventing the plant from absorbing water. Therefore, the plant must expend extra energy to obtain water, and cannot grow as well as a plant that easily obtains water. The other main ingredients in Gatorade, including electrolytes and citric acid, do not have a major effect on the growth of a plant. The water content in Gatorade is the only thing that assists a plant in growing. Tap water is fine for watering most plants, but it may contain trace amounts of chlorine and is likely fluoridated--and both of these

It is determined that the higher concentration of saline, that is added to the bean plants, the faster that they will die off. With the saline concentration of 1%, 1.5%, 2% and 3%, 2 plants on each concentration will be examined. Overtime a change in the length of stem, width of leaves and how many leaves should change over time. Osmosis plays a big part in the role of absorbing minerals and water into the plant.

I signed up to take AP Environmental Science this year because I was more interested in taking it than expanding on solely biology or chemistry. This course includes several different fields of study which is why I thought it would be very interesting and I would learn about several subjects compared to just one. Before completing any work for this course, my definition of environmental science would have been, the study of elements of the environment such as climate, soil, and water. I also would have thought that the term environmentalism meant simply protecting the environment. The difference between environmental science and environmentalism is that environmental science is the study of the environment which runs more tests and experiments

In such a project are the following problems that may or may not occur: whether to ozonator properly infuses the water fully, the effect of the water will wear off after a few days, and from one source ,”Ozone is very harmful to the lungs,”(CDPH, 8.). The same source says that this is safe to use in water because, ”the reactions are taking place underwater, where people are not generally exposed,”(CDPH, 8.). The best method for measuring the plant growth is through a height test because the only other option is to do a mass test and that would be hard to calculate with the soil and water inside. The best method for qualitative data is to take pictures because it would be hard to write down every single detail that

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

How did complex life cycles in trematodes evolve? (What are the hypotheses to explain how these life cycles evolved to include multiple hosts and larval stages?)

At first, I believed science and I were never going to be a compatible match. I’ve always enjoyed learning the topics, but I struggled at times to keep up with content. After taking AP Environmental Science, I was exposed to a different point of view of the science world that impacted my perspective on my own actions.

We know that light is an important part of both terrestrial and aquatic ecosystems. In a forest system both the canopy and the understory absorb light. The type of forest and leaf cover present determines the amount of light that reaches the understory. This can be measured using the LAI (Leaf Area Index), which is the amount of leaves per unit ground area. Light quantity in forests is affected by several factors such as tree species, age, and density.

The main purpose of this experiment is to examine how certain components in an environment can affect the growth pattern of a plant, or in this case, the Lemna minor, or duckweed. In this experiment, we use the pH level as a variable component to examine the population growth of the duckweed.

Plant cells react differently to osmosis than animal cells. When an animal cell is placed in a hypertonic solution, water will leave the cell causing it to shrink, this is known as crenation. When a plant cell is placed in a hypertonic solution the cell membrane will pull away from the cell wall, making the plant flaccid, this is known as plasmolysis. When an animal cell is placed in a hypotonic solution, water will rush in to the cell, causing it to swell and sometimes burst. A plant cell placed in a hypotonic solution will also swell due to water rushing in, but will resist rupturing due to the rigid cell wall. Plant cells become more rigid in a hypotonic solution.

Biodiversity presents occurrence of variety of species and their natural community in which they live. By the definition it is “The degree of variation of life forms within a given species, ecosystem, biome, or an entire planet. It is a measure of the health of ecosystems and is in part a function of climate.” (Rutherford) Ecosystem is on the other hand, “ community and its abiotic environment”( Rutherford). Biodiversity exists in every ecosystem, weather it is big one, or just ecosystem of one garden, it has the same importance because without it nature loses its ability to perform major functions needed for life on Earth, as it is oxygen production. Trough this investigation, two different ecosystems will be explored and
