The carrying capacity of Wisconsin Fast Plants (Brassica Rapa) in a 2-liter bottle growing environment Introduction In this lab we conducted an experiment in which we created a habitat in which plants grown; We will determine if the plants will grow successfully in this habitat. We will plant “Wisconsin Fast Plant”seeds, also known as (Brassica Rapa). The Wisconsin Fast Plants are a small, fragile sized plant that has a short growing period and produces seeds at a high density. We will observe them as frequently as possible and record the heights each day we make observations.…
The purpose of this lab is to examine cross sections from the leaves of C3 and C4 plants and to determine the morphological differences between them while relating those differences to their metabolism. In C3 plants the carbon dioxide is first incorporated into a 3-carbon compound. Their stomata are open during the day and photosynthesis takes place throughout the mesophyll cells. In comparison C4 plants, the CO2 is first incorporated into a 4-carbon compound. Their stomata are open during the day and photosynthesis takes place within the inner cells.…
Pinto beans or in other words common beans are the most abundant beans in both Americans, making it major source of daily nutrients for large number of civilians. This experiment was done to examine if the number of seeds used in a specific area would affect the growth process using two pots (Control, Experiment). Control pot had two Pinto beans, while the Experiment pot had four seeds. Both pots were placed in the same room with same amount of water supply and light.…
Average Metabolic Rate Difference of Goldfish in Dark vs. Ambient Light Introduction Metabolism is an interesting field of study to better understand what is happening inside of the body of different organisms that keep them alive. Goldfish (Carassius auratus) were used for this experiment since these small animals metabolism can be easily influenced by different variables. This is due to the fact that goldfish are poikilothermic whose internal temperature is influenced by their surroundings. Oxygen consumption was used to measure the metabolic rate when goldfish are in ambient light as the control and dark as the experimental variable.…
4. Write out the balanced chemical equation for photosynthesis (no peeking!). Sunlight energy + 6H201 + 6C1O2 —> 6O2 + C6H12O6 5. Based on the simulation experiments, what factors can affect the rate of photosynthesis in a plant?…
In this lab, we took four separate onion bulbs, labeled them A,B,C, and D, and put them in a beaker filled with water. We recorded the growth in number of roots and their average length for days one, two, and five. Then we put Bulbs B, C, and D in beakers with different amounts of caffeine and left Bulb A in water. We then recorded the number of roots and their average length on days two, three, and four. After that, we took and onion root form Bulbs A, B, C, and D, stained them, and looked for cells going through mitosis.…
Population Growth Lab Populations of different species interact with their environment in a myriad of ways. This may also impact the population, especially concerning its size. The question trying to be answered was how changes in the amount and nature of the plant life available in an ecosystem does, in fact, influence herbivore population growth over time. Answering this question will determine which environmental factor has the greatest impact on the population growth of herbivores. In this lab the herbivores, are rabbits, and the plant life is grass and weeds.…
The trendline shown is barely decreasing, which shows a negative correlation between the amount of carbon dioxide and and the percent of growth from the plants. However, it can be perceived that this trendline was negative for many other reason besides the limited amount of carbon dioxide. This proves that there were not enough constants in this experiment for reliable results; preventing the ability to draw conclusions from this…
Introduction: Leaf Disk float in water alone. When a solution consisting of a small amount of sodium bicarbonate is added to the water it causes the leaf disk to sink. As photosynthesis continues in the leaf disk it releases oxygen and causes the leaf disk to rise. While cellular respiration is occurring also the rate that the disk raise is an in implicit measurement of the net rate of photosynthesis. The independent variable in this lab is the solution and the light because it can be controlled.…
When comparing red light to white light, the rate of photosynthesis did have a significant change. However, white light was still more effective than either of the light treatments. This is because white light is composed of all colors, giving the photosynthesis to opportunity to absorb more from its specific wavelength that provides for the best rate of photosynthesis. A similar experiment was done with changing the color of light by using plastic covers on the lights. They also concluded that the results were inconclusive due to the minute change for the rate of photosynthesis.…
Research this chemical and state why you believe it was added to the tubes in both of these experiments. I believe it was added because it is an indicator that can change color in the presence of carbon dioxide and acts as an indicator of photosynthesis. Examine the three graphs below. Which do you think most accurately represents the results you would see if you were to increase light when performing Part A of the experiment? Why?…
its color led to the formulation of this experiment. The experiment utilizes chloroplasts of spinach leaves to test the different color lights’ effects on photosynthesis. Green light is said to be the least effective at driving photosynthesis on the electromagnetic spectrum due to being mostly reflected and transmitted instead of being absorbed. Conversely, red light and white light is more effective at driving photosynthesis (Reece, 2011). Thus, a hypothesis was created stating that the rate of photosynthesis will be greater with a red light bulb compared to a green or white fluorescent light bulb.…
The purpose of the Light, Color, and Solutions experiment was to determine how to use a spectrophotometer, understand the relationship between a solution’s visible color and its color absorption, and to derive, understand, and use Beer’s Law. Some background information that would be helpful included that the color of a solution was determined both by the colors it absorbed as well as the colors it transmitted. For example, if a solution was viewed as the color red, then red light was transmitted by the solution while the complementary color, green, was absorbed. Beer’s Law stated that the amount of light that passed through a sample was limited by the light’s wavelength,…
Discussion The purpose of our experiment was to compare the rate of photosynthesis and respiration of Brassica rapa in ambient carbon dioxide concentrations, but grown in variable CO2 concentrations. The results we concurred from this experiment were the same as we had hypothesized, the variable growth conditions of the B. rapa plants had no significant difference on the rates of respiration and…
