In Burns Bog and Watershed Park, the light was blocked at certain times because of the cover of the trees. Light intensity affects the rate of photosynthesis as with more sunlight, more carbon dioxide can be produced for the plants to grow. The types of vegetation is affected by light intensity as when the amount of sunlight decreases, the growth decreases as well. This is why SWMA has more grass plants such as, Aster and Colonial Bent Grass. According to the Spearman's Rank Correlation Coefficient, the correlation coefficient of light intensity and Aster is 0.4.
Results The data obtained from the experiment had undergone statistical analysis using t-tests and the results were recorded in Figure 1.0 and Figure 1.1 above. According to the data obtained in Figure 1.0, the p-value is less than 0.05 in all 5 treatment solutions. It is also shown intensity Figure 1.0, the calculated t-value of each concentration of NaHCO3 in each treatment is greater than the critical t-value.
The most important result from this experiment is that it suggested that the increase of Carbon Dioxide, will drastically increase the growth mountain maple in the covered (from the sun) parts in a forest, in the meantime any increase in the temperature of the soil will nullify the increase of light, as we know is to be the main ingredient for photosynthesis. 5.

How did different colors of light affect c02 consumption in spinach leaves? Background Photosynthesis is a process by which plants and other autotrophs make their own food using sunlight energy. Plants take in water, carbon dioxide, and use sunlight energy to create glucose and oxygen. Plants use the glucose as energy and release the oxygen as a by-product.
Photosynthesis/Scientific Method Worksheet 1. State and explain your pre-experience hypothesis: We were supposed to place (Elodea) in two tubes, which one should closer to a light source and the other with no light on it. The experience consisted in observe and count the amount of bubbles coming out from the plant in both tubes.
All organisms use food molecules, like glucose to produce ATP. The production of ATP occurs during cellular respiration. ATP provides the cells with energy that is necessary to produce oxygen. The seeds/plants are autotrophic organisms, which produce their food from the energy that the light provides them. To release the stored energy within the food molecules, the germinated seeds carry out respiration and the release of carbon dioxide.
The plants with 200 ml topsoil were projected to have the highest average height according to the original hypothesis of increased plant growth due to an increase on the amount of topsoil added. Moreover, the original hypothesis was refuted as the plants with no topsoil in the control had a higher average height than the plants with 25 ml topsoil. The mixed red and green color on the leaves of the plants with 25 ml topsoil indicated possible deficiencies in phosphorus which might have slowed their growth. Moreover, the mixed red and green color on the leaves of the plants in both 100 ml and 200 ml topsoil also indicated a possible phosphorus deficiency which may have resulted in the slower growth of the plants despite having greater amounts of topsoil. The experimental results might have skewed due to the over fertilization of the radish seeds which might have led to excess nutrient levels which are unsuitable for radish plants as they require little to no fertilization for growth (Chase, 2018).
Because carbon dioxide is absorbed by the plant during photosynthesis less carbon dioxide present in the chamber is a sign that photosynthesis is working. The four lights used for this experiment range across the light spectrum on both sides in order to test a wider variety of wavelengths. All lights will be placed directly on the spinach leaf at the same distance so as not to give any spinach leaf a different light intensity, which could affect the data. This experiment will be able to show which light, ranging across the light spectrum, will allow the Spinach to perform photosynthesis more efficiently.
photosynthesis and cellular respiration are extremely important in the cycle of energy to sustain life simply because nutrients would not metabolize in a productive manner. Both have numerous stages in which the process of energy occurs, and relationships with organelles located in the eukaryotic cell. Photosynthesis is a process by which green plant and other organism manufacture their food using sunlight to synthesize foods from carbon dioxide and water while cellular respiration is the oxidation of organic compounds that occurs within cells, producing energy for cellular processes. Photosynthesis occurs within organelles called chloroplasts. These organelles can absorb light, and are located inside of leaves.
Introduction Purpose The purpose of this lab is to study soil PH, soil salt concentration, osmosis and light. To identity potato weight change in sodium chloride. To determine the growth of plants scientist, farmer and business owners often work to determine the optimal conditions for their plants, which involves a variety of test and a large amount of trial and error over many years.
(Levitt, 2004, p. 182). His statistics are compelling, but the reasoning seems slightly irrelevant, as argued by Baumer and
The purpose of this lab was to measure the amount of CO2 gas given off by germinated peas under certain conditions of light. We conjectured that the more amount of light the peas are exposed to, the higher the respiration rate they will have. Our data supported this because it showed that the germinated peas that were exposed to light 24 hours before the experiment had a steeper slope (as seen in table 1), therefore having a greater respiration rate. The peas that were not exposed to any light 24 hours before the experiment had a reduced rate because of its lack of exposure to light. Both pea’s respiration rates showed that the more light the peas were exposed to, the greater respiration rate they would have (Figure 1).
Introduction: In this task I will be researching the effect that acid rain has on the rate of plant growth. Acid rain is any type of precipitation with a high pH, with high levels of nitric acids. The reason why I had chosen this topic was because acid rain seems to have a great effect on the effect of plant growth, and plants play a very important role in our ecosystem. Acid rain is a major problem in our environment when we are not able to neutralize the acidity.
Research Question: How does the presence of light impact the rate of transpiration in plants? Aim: The aim of this experiment was to investigate how the presence of light affects the rate of transpiration in plants. Hypothesis: As light intensity increases, the rate of transpiration (water uptake) in a plant increases.
Introduction Plants are a major necessity in the balance of nature, people’s lives, and our terrain. We may not realize it, but plants are the ultimate source of food for almost 95% of the world population so says the National Group of Food. It’s a fact that over 7,000 species of plants are being consumed today. Plants are one of the reasons that we get clean water; as they help regulate the water cycle.
