Baking soda (sodium bicarbonate, Na HCO3) breaks down to release CO2 when mixed with water, so adding it to the water increases the availability of CO2.By placing the Elodea plant into water containing varying levels of baking soda, we can also investigate the effect of carbon dioxide availability on the rate of photosynthesis.…
In the lab with germinated and dry peas along with glass beads, determining the rate of respiration in each different type of seed was the goal. The hypothesis stated that since the germinated peas were still alive, they would contain a higher rate of respiration needed to remain healthy compared to the dried peas and glass beads.…
In experiment one, involving the rate of respiration of germinated peas when exposed to a variety of different temperatures. From a general standpoint the data collected matched the hypothesis formed, as the temperature increases the rate of respiration will increase as well. This was shown as the average ppm of oxygen was taken from each group. Comparing the data from the class is shows the effect of human error on the results. For example group #4 seemed to have back wards results this may have been due to an improper seal on the oxygen sensor.…
Objective: To calculate the rate of CR from the data. To then relate gas production to respiration rate. Then test the rate of CR in germinating versus non-germinating seeds in a controlled experiment and then test the effect of temperature on the rate of CR in the germinating versus non-germinated seeds in a controlled experiment.…
The rate of respiration in mealworms from the twelve experimental tubes in the light treatment ranged from 0.0489 mL O2/g/hr to 1.1611 mL O2/g/hr. The average rate of respiration was determined to be 0.4034 ± 0.1886 mL O2/g/hr. The rate of respiration in mealworms from the six control tubes of light treatment ranged from 0 mL O2/g/hr to 0.0859 mL O2/g/hr. The average rate of respiration of them was determined to be 0.0208 ± 0.0068 mL O2/g/hr. The CI bars of the experimental tubes and the control tubes in this treatment did not overlap, so they were determined to be significantly different from each other.…
Due to the control, non germinating peas/beans are releasing less CO2 ppm than the 24 hour and 48 hour germinating peas/beans. This can be seen when the control from 0-5 minutes was at -76 ppm, while the 24 hour beans were at +374 ppm. The alaskan peas also saw this same type of pattern from 0-5 minutes. The control for the peas was at -176 ppm and the germinating peas were at +1,056 ppm. Since this lab was conducted with precision, and the sensors were not broken, or tampered with before, during or after the experiment, this data is accurate which leads to precise…
Abstract: This report examines Cellular Respiration and its functions as well as its function in germinating and non-germination peas. Cellular Respiration can best be described as a complicated string of chemical reactions. The complete Cellular respiration process begins with Glucose being oxidized, and the potential energy is transferred to the ATP molecule. The ATP molecule is now free to supply energy to the various processes within the cell. Water and Carbon dioxide are released during the process. This experiment aimed to conclude whether or not non-germinating peas are undergoing Cellular Respiration before they begin germination. This particular experiment required the following equipment: A thermometer, an Oxygen gas sensor, and a Carbon dioxide gas sensor. Temperature was also a factor in this experiment, as the effects of temperature on the rate of Cellular Respiration was also under study. The conclusion(s) of the study was/were as follows: Germinating peas experience Cellular respiration at a much faster rate than non-germination peas (however, non-germinating peas do undergo cellular respiration, but a much slower rate); it was also found that cooler temperatures affect the rate of respiration by slowing the process down.…
photorespiration rates increase with increasing temperatures in C3 plants, the loss of CO2 by photorespiration in C4 plants…
Notes about bean germination: * The time to germination will decrease if you soak the beans overnight * It may take 7-10 days for the beans to ‘sprout’ * Make sure the paper towels remain moist for the duration of your experiment…
Germination in plants is the process in which dormant seed begins to grow and sprout under certain growing conditions. The English pea, also known as the garden pea, is a member of the legume family and is known to grow roughly three to four inches long. Research shows that it only takes approximately 1 week for the seed to start to germinate. There are many things that can affect, the growth of the pea seed such as; temperature, moisture, planting depth and sunlight. The pea grows best in temperatures between 7˚C -14˚C, any lower or higher temperatures may affect the seed germination. Often it is recommended for the seed to firstly be planted indoors, where there is a controlled environment. Similar to most living things the English pea needs moister to survive. Pea seeds deprived of water shrivel and die, while those that receive too much water become water-logged and start to decay. Proper watering ensures that the soil around the bases of the pea vines is damp but not saturated, with additional watering scheduled during dry weather.…
In this lab we are measuring the amount of oxygen used in both germinating and non germinating peas. We are measuring the oxygen consumption by taking a reading of a respirometer submerged in two water baths. The first bath will be cold water and the second warm to determine the effect of temperatures on oxygen consumption. Our negative control will be glass beads to measure to increase or decrease in atmospheric pressure or temperature changes. There is a direct relationship between oxygen consumption and Carbon Dioxide produced, therefore the more O2 consumed the more CO2 produced. To keep the amount of CO2 produced from canceling out any pressure gained or lost from the consumption of CO2 we are adding KOH(Potassium Hydroxide) to the respirometers. Since the CO2 will be selectively removed the change in the volume of gas in the respirometer should be directly related to the oxygen consumed. In this experiment the germinating peas, in both water baths, should consume much more oxygen than the non-germinating peas or the glass beads, because germination has began thus accelerating cellular reactions and the rate of respiration. The cold water bath should slow the respiration down in all three respirometers.…
This study was undertaken in order to compare the respiration rate of the field cricket, Gryllus bimaculatus, to that of the house cricket, Acheta domestica. This was done by observing the CO2 output levels (in microlitres/min) of both cricket species. Our results showed that the field cricket, Gryllus bimaculatus, had a greater CO2 output than the house cricket did, which suggests that the field cricket has a faster rate of respiration than that of the house cricket. There may be sever possible factors that contributed to these results such as the physical fitness of the particular cricket, the medical condition of the cricket, and…
The 95% confidence intervals describe the extent of experimental errors within this experiment. Experimental errors give imprecise measurements for result analysis. If the actual temperature recorded was not exact compared to the desired temperature, the results may give false belief. Other experimental errors that can affect cricket respiration rate is how far the respiration chamber is submerged in the water baths, not allowing the crickets to acclimate at new temperatures before recording CO2 concentration, incompetency in eliminating previous CO2 from different temperature stations before starting a new trial, and the possibility of the drierite dessiccant failing to absorb excess moisture. Even though experimental errors are inevitable, the results do show that as temperature increases, cricket respiration rate also increases. Since crickets are ectotherms, they tolerate inconsistent body temperatures depending on the amount of heat gained from their environment. Crickets use the heat absorbed as a source of energy for their bodies to function and increase metabolism. The more heat absorbed the more energy for cells to do work, such as respire. This explains why the cricket’s respiration rate was the fastest at the warmest temperature 40°C. The results of this experiment support the hypothesis relating temperature and respiration rate of crickets. If respiration is a process of metabolism, then the crickets have a higher metabolism…
I eat some corn during lunch and then cellular respiration takes place. During the process of cellular respiration the glucose and oxygen I took in will be turned into carbon, water, and ATP. I will expel this carbon through my lungs. This carbon then is used by photosynthesis of phytoplankton in the water. During the photosynthesis that takes place, sunlight, water, and carbon are taken in by the plankton and then a fish eats this phytoplankton and this organism dies. When the fish dies it decomposes, and when organisms decompose they release carbon dioxide into the air. When the carbon dioxide is in the air it is used by some spinach plants. The spinach plant uses the carbon dioxide during a process called photosynthesis.…
This report discusses an experiment to study the rate of aerobic cellular respiration in aquatic organisms which are Elodea (aquatic plant), Snail, and Goldfish, by measuring carbon dioxide production. Because ectothermic organisms (Elodea, snail, and goldfish) were placed in completely covered beaker, each organism would produce different amount of carbon dioxide. The objective of the experiment is to measure carbon dioxide production in three aquatic organisms, and to determine and compare the rate of cellular respiration in each organism. Aerobic respiration is the process which body obtains energy by using glucose + oxygen; this reaction takes place in mitochondrion in a cell; And the result of the reaction are carbon dioxide, water, and energy in the form of ATP ( adenosine triphosphate) (Hoefnagels, 2012). According to Biology 6th Edition, plants use light to convert atmospheric carbon (CO2) into carbohydrate (Johnson, 204). So I predicted snail would respire at the fastest rate and produce more CO2 because its weight was heavier than other two…
