Aerobic cellular respiration is required for the survival of all organisms. The rate of respiration differs for different types of organisms, based on the functions of the organisms. Plants, represented by germinated and ungerminated Pisum sativum seeds in this experiment, do not require as much respiration as animals, represented by Zophobus morio larvae, as animals require higher respiration rates to be able to move. As temperature increases in both organisms, the rate of respiration will also increase. In this experiment we observed the effects of iodine on the surface of a cotyledon of a germinated P. sativum seed. We also observed how 20℃ water affected ungerminated P. sativum seeds. Furthermore, we compared the effects of heat on respiration for live and dead P. sativum seeds. Finally, we tested the effects of different temperatures on germinated P. sativum seeds and Z. morio larvae. Our results indicated that germinated P. sativum seeds and Z. morio larvae both had increased respiration rates as temperature increased. Their lower and upper temperature limits differed slightly, based on the organism’s typical environment. In conclusion, we found that it is important for plants and animals to have different respiration rates to suit their functions, such as the ability for animals to move.
In this cellular respiration experiment, we used germinated and ungerminated P. sativum seeds to explore the effects of temperature on respiration rate. P. sativum seeds are cool-weather plants from Europe and Asia. Due to the cool environment they live in, they have a tolerance to cold temperatures. Even with that tolerance, survival is difficult for them. P. sativum seeds that live in temperatures ranging from 25℃ to 45℃ have low surviva...

...rate of the germinated P. sativum seed increased as temperature increased. Similar to the larvae, the respiration rate began to decrease at around 40℃. This is due to the effects of the seeds getting hot. As the water around the test tube begins to boil, the germinated seed gets dehydrated and starts to die; germinated seeds require water to survive, and dehydration deprives them of water.
Our results indicate that animals, indeed, require higher respiration rates than plants, as animals have movement and plants do not. Animals require a faster respiration rate to help them to make up the energy that they lost when they move around (Lindeman, 1942). Since plants do not tend to move around, the respiration rate must be slower than animals. Therefore, our results indicating that animals have changed their rate of respiration faster than the plants did not surprise us.

The Effect of Temperature on the Rate of Respiration in Yeast Essay

- The Effect of Temperature on the Rate of Respiration in Yeast There are two types of respiration in yeast: Aerobic: [IMAGE] Anaerobic: Glucose [IMAGE] Carbon dioxide + ethanol + energy Respiration is controlled by enzymes, which are proteins which speed up one or more biological reactions. Within any cell many chemical reactions are going on at any one time. Yeast has many different types of enzymes that speed up respiration. Prediction I predict that as temperature increases, the rate will also increase, until a certain optimum temperature, after which, the rate will decrease until the rate is zero as respiration has stopped completely....   [tags: Papers]

Essay on The Effect of Temperature on the Rate of Respiration in Yeast

- The Effect of Temperature on the Rate of Respiration in Yeast I have chosen to investigate the affect temperature has on the rate of respiration in yeast. I will use an experiment to determine whether the yeast's rate of respiration will be quicker, slower or if it does not change when the temperature is varied. Scientific Knowledge The first thing to say about enzymes is that they are proteins and they are found in all types of organisms from humans to viruses....   [tags: Papers]

Essay on The Effect of Photosynthesis and Respiration on the Environment

- The Effect of Photosynthesis and Respiration on the Environment The environment can be defined as the surroundings in which as organism lives, including the climate, the physical and chemical conditions of its habitat and its relationship with other living things. Given the above understanding, it is therefore important that the right environment factors are in existence for some chemical reactions to take place. In the absence of optimum environmental factors, organisms would be compelled to adapt themselves to the prevailing environment....   [tags: Papers]

Essay The Effect of Different Sugar Sources on Yeast Respiration

- ... Since 2006, there have been 1,500 species of yeast identified by scientists. Yeasts make up only one percent of all fungal species found in the fungi kingdom. Yeasts can be found anywhere, throughout nature, on top of plants, in soil, and more commonly on the bodies of humans and other animals. Yeast is commonly used when brewing alcohol (beer, wine, and whisky), and for making leavened bread and cheese. Carbohydrates are a major molecule in biological systems, made up of saccharides that can be strung together into disaccharides, trisaccharides, and polysaccharides or as small molecules called sugars....   [tags: sugar substitutes, saccharin]

Lab Experiment: The Effect of Temperature and Respiration Essay

- Introduction: Respiration commonly known as the inhalation and exhaling or breathing has a more little known definition. This is the definition that involves the cellular level of eukaryotic cells. Cellular respiration may best be described by the following equation: C6h1206+602-6CO2+6H20+36ATP. ATP that is the energy needed for a cell to function as part of cellular respiration. ATP is needed to power the cell processes. If cells are denied energy they will die. The second law of thermal dynamics says energy is lost in the form of heat whenever energy changes form....   [tags: essays research papers]

Two Categories of Organisms: Poikilotherms and Homeotherms Essay example

- INTRODUCTION Every living organism has a metabolism. Metabolism is the sum of the chemical reactions in one’s body, including both anabolic and catabolic processes (Pfleugal, 2014). These processes require energy that is obtained through the organism’s respiration. Because an organism’s respiration is linked to its energy consumption, researchers can observe changes in the metabolism of organisms by looking at their respiration rates. It is possible to measure respiration by looking at either the change in oxygen or carbon dioxide concentration in a closed environment....   [tags: metabolism, anabolism, fish]
