Plant Competition

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.

The purpose of this simulation is to see how these three organisms will interact with one another in the same environment. We will see how the populations of these organisms change by modifying parameters specific to each organism and how changing

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.

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

Competition happens between two or more things. In talking about plants they compete with each to survive. When competing against each other to survive they are using soil, water, nitrogen, and space. In using theses resources and having theses available gives the plant a greater chance in living. Even though plants compete environmental wise it is still scene that there is a lot of unknown to why plants compete. Some researchers believe it could be because of the root size of an individual plant or the size of the seed, which gives it better competition in surviving (Miller, 1995). Different types of competition can happen between plants likes intraspecific and interspecific competition. Miller (1995) believes there is not enough research shown to make a determination as to why competition between plants happens and that there should be research done in looking at the evolution of plants in different environments where they can compete with each other. In looking at competition in plants in class the experiment that we conducted looks at the Brassica rapa in a intraspecific competition in different densities. Miller (1995) found that the B. rapa in intraspecific competition did have increase in the number of flowers that were produced. Comparing this to the finding of Miller, when looking at different densities of plants in a interspecific competition could the B. rapa have more of a change in growth because a higher density will have more seeds and the B.

The “Brassica rapa” is a fast plant known as the field mustard. This plant is well known for its rapid growing rate, which makes it an easy breeding cycle and easy to pollinate. In giving so this makes “Brassica rapa” a great participant for testing Gregor Mendel’s theories of inheritance. The “Brassica rapa” acts like a test subject in testing cross-pollination giving the understanding to the dominant allele of colored stems. There are different colors that are visible on the stem that are above the soil; the colors vary from green to purple. P1 seed was ordered, germinated and cross-pollinated until germination of the next off spring of plants were also done. It was

Each quad of soil had 2-3 seeds in it along with either 0, 3, 6, or 9 pellets of fertilizer in each quad to possibly get 4 plants total. Two types of fertilizer exist, organic fertilizer and synthetic fertilizer. Gardeners.com says that, organic fertilizers are made from organic materials. (1) Organic fertilizers also prevent the plant with a better structure, improving the structure of the plant. (2) Synthetic fertilizers are fast-acting fertilizers but also come in different forms such as granule, spike and pellet. (2) This kind of fertilizer is also known for seeing green in the plants quicker and quick-hit of nutrients for the plants. (2) There are advantages and disadvantages of using fertilizer. Plants can have a quick action of growth and are more defined when using fertilizer. (3) But sometimes there is a chance of using the fertilizer to much causing damage to the whole soil ecosystem. (3) Over two weeks we observed the growth of the fast plants and recorded the data of the height. By the end of the two weeks, we also recorded the weight of the fast plants. I hypothesized that each quadrant was going to be different plant growth, with the quadrant of 6 pellets (quadrant C) being the fastest growing plant. My individual results showed that the quadrant with 9 pellets (quadrant D) had the most results with growing in

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

This report discusses an experiment to study the relationship between the ecological niche and competition. The hypothesis formulated states that if competition traits are identical and resources are abundant than multiple species will be able to coexist, and if one species has an advantage over the others than this species will be more likely to out compete another species for resources. The objective of this experiment is to use a simulation model of a rabbit pen containing four different “species” of rabbits. The model establishes rules for each species that are based on a number of important characteristics reflecting their ecological niches and their competitive abilities. These

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

Ecology can be defined as the study of organisms in relation to other organisms and their surroundings. It is clear that there are many influential factors in species ecology, but maybe none more so than the role of resource competition. Competition occurs when there is a limited resource available to one or even multiple species. When there is a lack of available resources, species will often compete among themselves and with other species to gain the status of the top competitor. In this paper, we will review studies on how resource competition impacts the ecology of an assortment of species.

To survive in the wild, plants must form defenses to protect themselves from herbivory. The main physical defenses are thorns, used to harm the herbivore, or predator. This harm to the animal triggers a negative response, therefore causing the animal to avoid that plant in the future. Plants commonly eaten sometimes form a sour or bitter taste or odor to deter herbivores. This mechanism causes herbivores to stay away from such plants and avoid eating them. In addition, poison serves as an effective deterrent, causing animals to stay away due to its effects. These poisons may cause vomiting or extreme illness, and in some cases, death, which warns herbivores to avoid such plants through experience or from warnings by other animals. A final

A plant is any of the boundless number of living beings within the biological kingdom Plantae, these species are considered of low motility since this species generally generate their own food by sunlight. They incorporate a large group of commonplace life forms including trees, forbs, bushes, grasses, vines, plants, and greeneries. In this task we are experimenting the relationship between light and plant growth by growing plants in three different lights which are red light, blue light and white light. As I stated above that plants generate their own food by sunlight. Sunlight can be broken up by a prism into respective colors of red, blue, orange, yellow, green, indigo, violet and white. All this lights have specific
