Tillandsia Air Plant Lab Report

Plants are found everywhere on earth, up high on the ridge and down low in caves and caverns. The types of plants that live in these places depends on many factors. These factors are separated into two different categories, the biotic factors and the abiotic factors. Some of the biotic factors include, predation, competition, and habitat destruction. Plants with limited competition and large amounts of resources will be in a higher abundance than plants with limited resources and higher competition rates will be confined to areas and either out competed or will be the dominant species. Certain plants adapt to these factors and thrive and others don’t do as well. Some of the abiotic factors include, sunlight, water, temperature, and wind. These

1. For this experiment, what were the independent variable and the dependent variable? What were the constants?

4. The Independent variable is the dissolved oxygen and the dependent variable is the number of fish observed.

might affect the fitness of each variant. In other words which factors might increase plant growth, survival,

A plant's growth ability is dependent on its ability to acquire the resources it needs to survive. Competition such as interspecific and intraspecific, limiting resources, and population density affect the fitness level of a plant. This experiment was conducted in order to test the capability of collards and radishes to grow in manipulated densities under interspecific and intraspecific competition. I hypothesized that both collard and radish plants will grow more efficiently in single species pots under low-density conditions. I also hypothesized that in the mixed species plots the radishes will be more fit to survive and grow better than the collard plants in both the high and low-density pots. Both high and low density and single and mixed species plots were planted and results were observed. There was a significant

The independent variable is sugar concentration. This will be changed by using solutions with different amounts of sugar (2%, 6%, 10%).

When monosilicic acid and water travel throughout a plant’s root system and into the plant, the acid collects inside tissues. Developing microscopic inorganic silica molds; called phytoliths. Phytoliths are produced in almost every environment in the world, consisting of silicon dioxide, water, organic carbon, and trace elements of aluminum, iron, magnesium, and several others. The transparent molds can be one to over one-hundred micrometers in size. Phytoliths can serve the plant and us in several ways. It permits some plants to stand stiff and allows for sun exposure. It also assists the plant in trapping dangerous elements that could harm the plant. Fields including paleontology, archaeology, primatology, and environmental science greatly appreciate the existence of phytoliths. Phytoliths live long after the plant dies; they exist for tens of millions of years, and in extreme temperatures. Ecofacts such as phytoliths are tremendously beneficial when finding a plant’s family, genus, species,

The figure 6 represents the dry weight of the plants. This graphs shows that the dry weight of cabbages is greater than the onions. The dry weight of the control groups (pot 5 and 6) are similar in weight. Finally, the tomatoes weigh more than cabbages.

In Encyclopedia Britannica, the Elodea plant viewed as a waterweed. An intrusive water plant starting from the North American mainland. There utilized as a part of analyses and in aquariums in view of a lot of oxygen that the plants produce. As indicated by the Colorado Master Gardening system's cultivating takes note of, the blend of daylight, carbon dioxide from the air, and water from the dirt respond with each other to deliver oxygen. The paper likewise expresses that the measure of oxygen delivered is reliant on the measure of light and water accessible. Elodea, being a water plant, the measure of the oxygen is fundamental to people for the utilization of submerged investigations and circumstances in which a man may require the oxygen

In this study, Plant A, which received twenty-four hours of artificial light every day, will reach the maximum height amongst all plants. Due to the maximum access of light, Plant A will therefore have the most access to energy, which is a vital source of food to the bean plant. With more energy available to the plant, photosynthesis can provide an abundance of food availability which will cause the plant to thrive more successfully.

The hypothesis was that carbon was the factor that impacted plant mass the most. According to the data, this is accurate. although the plants that had 10 tablets grew the least, they still had the most mass, meaning that the carbon increased the mass of the plant regardless of how much it grew. The first set of data showed that the amount of carbon affected the more carbon, the more mass there was. The second set of data mirrored this. The first set of data for the mass gain for the control was 6.9 grams, the plant with two tablets had a mass gain of 10.6 grams, the plant with five tablets had a mass gain of 16.3 grams, and the plant with ten tablets had a mass gain of 30.6 grams. For the second set of data, the control had a mass gain of 6.5, the plant with two tablets had a mass gain of 8.5 grams, the plant with five tablets had a mass gain of 5.4 grams, and the plant with ten tablets had a mass gain of 46.5 grams. The average mass gain for the control was 6.7 grams.

Among numerous environments there can be certain plant species that are found in high abundance. The reason for this is most likely due to competition and in certain environments that a specific plant species is in competition with the other species. One of the major reasons for competition among plants species is for resources (Aerts, 1999). If the environment has dense canopies and is abundant in nutrients then the competition among plants will be mainly for sunlight (Aerts, 1999). In nutrient-poor environments where water and soil nutrients are scarce there will most likely be competition among the plants for those limited nutrients (Aerts, 1999). A paper written by Aerts (1999) discussed competition, the purpose of which was

Our lab investigated the morphological characteristics of leaves found in the sun and shade on various species of maple and oak trees around campus. Our null hypothesis was Acer and Quercus acclimate similarly with regards to SLW (specific leaf weight), size, and sinuosity. Our hypothesis was Quercus acclimation is greater than Acer SLW, size, and sinuosity. We tested these hypotheses by picking small sections of a branches from both maple and oak trees. A group was assigned either a maple or an oak tree, and needed a total of three different trees per group. Once three different trees were chosen, groups needed three shade leaves and three sun leaves of off each different tree. In total, each group should then end up with 18 leaves for testing. After collecting the leaves, we ran them through the LiCor 3100 leaf area meter to identify the area of each leaf. Major results found by the classes’ mutual data was each one of our p-values were greater than .05. This means that we failed to reject the null hypothesis. Thus, the lab results do not support our hypothesis that Quercus acclimation is greater than Acer SLW, size, and sinuosity.

Leaves of different species were weighed in mg and recorded, then placed into a mesh bag in three separate areas of bag, separated by plastic string weaved through mesh. Rock was placed into middle segment to weigh bag down over the three areas.

Measurements to determine lodging tolerance are mostly taken around bud to mid-bloom stage (Johnson et al. 2008). They reported two methods used in carrying out these measurements and subsequent rating; 1) spaced plants trial and 2) solid seeded plots. In the spaced plant method, rating was done based on the percentage of erect stems within plant rows while in the solid seeded plots method, plots were rated based on percentage of erect stem within the plot.
