Cellular Respiration Lab Report

This scientific experiment is to gauge the amount of kernels popped when the storage temperatures of the kernels are changed. Does freezing popcorn kernels for 24 hours yield more or less popped kernels than popcorn kernels stored at room temperature? By performing this experiment we can decide how to maximize our food potential. We will purchase six identical brands of popcorn from the local food store that have the same ingredients, weight and brand name. We will take three of the bags of popcorn kernels and store it in a standard household freezer for twenty four hours. The temperature

Cellular respiration is going on in every cell in plants. It is interesting to know there is several of factors that affects cell respiration in plants for example ph. levels, temperature, oxygen, sugars. Germinating seeds carry out cellular respiration processes in much the same way as plant and animal cells do (Jeanty). Plant seeds respiration requires enough to maintain food or nutrients. The experiment that was done is testing the rates cellular respiration of germinating lentils that were soaked in different liquids which are water, juice, cola, Gatorade and milk. The hypothesis one is the highest rate of respiration is going to be the germinating lentils in water. The second highest rate of respiration is juice. The third is Gatorade. The fourth highest is milk. The lowest rate of respiration is going to be with the germinating lentils in cola.

According to Figure 1, the production of carbon dioxide changed based on the temperature the chickpeas were placed in. It seemed that the chickpeas placed into the ice bucket at 5°C produced the most carbon dioxide; however, this is not the case since the figure is only showing measuring the amount of ppm’s recorded by the carbon dioxide sensor. To get an accurate determination if temperature affected cellular respiration of chickpeas, finding the slopes of the lines was necessary which was done in Table 1. This is done by using the mathematical formula m=(y2-y1)/(x2-x1) with the “y” being the y-coordinate and “x” being the x-coordinate. To be consistent the coordinate points at the 10 second and 240 second mark were used to find the slope

Figure 1. Rate of oxygen consumption of boiled and unboiled germinating peas. As cellular respiration occurs, more oxygen is consumed, with more oxygen being consumed (high rate of aerobic respiration) by the unboiled germinating seeds compared to the boiled seeds which virtually respired (lower rate of oxygen consumption compared to unboiled peas).

Although, some factors that could have influenced this experiment was heat given off by the lamps, the restriction of the gas chamber, and how much CO2 there was in the chamber. Photosynthesis is also very heat sensitive, which is why when recording the O2 rates in the dark the lamp still needed to be on. The gas chamber restricted the flow of the natural environment along with already having a certain amount of CO2 in the chamber that wasn’t measured. These could have influenced the

A light bulb was used to create the hot temperature, one of the windows inside my house was used to create the room temperature, and my refrigerator was used to create the cold temperature. The seeds were in the various water temperatures for an hour each, every day for 14 days. The seeds were dried in between. This study showed which of the tested seeds germinated the most in the different water temperatures. The sweet corn germinated the most seeds in the room temperature tests, while the watermelon seeds germinated the most in the hot water temperature. The sweet corn germinated the most seeds again, in the cold-water temperature. The green bean seeds did not germinate efficiently in the hot or cold-water temperatures. All three seed types germinated well at the room temperature. Since light is also a factor that affects seed germination, the individual cups were placed in three different lights: with a light bulb, near a window and with little light. Based on the results of this study, the seeds that required sufficient amount of water temperature and light were able to germinate the

To begin the Cellular Respiration lab, have the lab set up as ordered on the lab manual. After reading its beginning instructions, the lab should be ready for testing the carbon dioxide concentration that is inside the chamber. Procedure should follow by weighing 10 grams of the germinating mung beans then the beans should be placed inside the Testing Chamber. Next, insert the carbon dioxide sensor with the germinating mung inside the Testing Chamber and form a closed seal. Start the machine by pressing play and collect the corresponding data. By following this procedure, calculation of the carbon dioxide concentration for dormant mung and glass beans are eligible. The variables that are controlled in this experiment are the quantities, such

This article synthesizes the effects of temperature on the rate of cellular respiration. The method used employed the use of gas sensors and a respiration chamber to test how different temperatures influenced the rate of cell respiration in worms. Based on this experiment, it was noted that temperature indeed does affect the rate of respiration in cells. Low temperatures were seen to slow down the rate of respiration while extremely high temperatures were also noted to slow down the rate of respiration. The results of the study are important in finding the optimum temperatures in which organisms can thrive in and also contribute significantly to the discipline of respiratory biology which contributes to understanding of biological connectivity

We had three sets of ten spinach chads that were submerged in CO2 water and put under different wattages of light: forty, seventy-five, and one hundred . Chads under the forty wattage only had six rise out of ten, chads under the seventy-five wattage light had all ten rise, and chads under the one hundred wattage light had all ten rise under ten minutes.

Our hypothesis was rejected because the plant in the cold temperature of 0°Celsius, had the greatest amount of oxygen produced from the starting point of 24% with a 1.60% increase. The room temperature of 23.33°Celsius was a close second with a 0.70% increase from the initial amount of 24%. The hot temperature of 40°Celsius was the lowest with a decrease of -2% from the starting amount of 24%. We noticed that the amount of oxygen produced increased as the temperature decreased. Though we believe if the temperature was lower than 0°Celsius then our results would be different, and the plant wouldn’t produce as much oxygen. The rate of photosynthesis depends on: light intensity, temperature, and the availability of carbon dioxide, and water. When

If we take 50 germinating wheat seedlings, incubate them at 37°C for 30 minutes, we take another 50 germinating wheat seedlings and keep them at 25°C, put each group in five separate respirometers (each containing 10 seedlings), add five drops of NaOH to each respirometer, submerge the open tip of the respirometer in water and wait for 30 minutes, then the group of germinating wheat seedlings that were incubated at 37°C will have a lower specific respiration rate than the group of germinating wheat seedlings at

The method used for this experiment was the one listed above. Although some of the results vary in some figures, there is evidence that the temperature of the water is linked to increasing the rate in osmosis in the onion cells. Shown in Figure 1 and 2 the cells have swelled, as a result of the increase in water temperature. This may be explained by the Kinetic Theory

It is hypothesised that the dicots (dwarf beans) will have a faster growth rate then the wheat. The aim is compare the growth and germination rates between the monocots and dicots. It has been found and clearly visualised so far that the beans are germinating faster. It also clearly visualises that the wheat seeds are continuously no make much progress. During the experiment currently many changes had have to been made. One example of the change made was adjusting to more or less water due to a public holiday on the 19th of October. Throughout this experiment the days the plants were watered on were Mondays and Fridays. Each time when watering the plant, the measurements, such as height, length and so on were observed and recorded into a

In terms of having the greatest output of carbon dioxide and net evolution of oxygen, the second plant with the 40% level of rubisco carboxylase was the highest. It was the second plant that reached almost forty with the first plant never getting past thirty and the third plant barely getting to ten. It seems 40% level of rubisco carboxylase offered the second plant peak operating performance. This is the key difference from plant one and plant two. They share similar growth rates in the charts and allow for close to the same levels of performance, but differ in the efficiency of said performance. In terms of plant metabolism, there is slightly more carbon dioxide absorbed in the tobacco

To test our hypothesis, we begin our experiment with planting Mung beans and provide them the equal amount of
