Essay On Spinacia Oleracea
Spinacia oleracea, is a highly adaptable organism, with the ability to grow virtually universally. While S. oleracea can tolerate a relatively high range of growth temperatures, it generally thrives in cooler environments of approximately 20ºC. As global warming becomes an increasing issue of global concern, it is becoming increasingly essential to determine the effects environmental temperature change will have on these globally depended upon organisms. The process of photosynthesis allows plants to synthesize glucose, and ultimately, ATP within of the presence of light, utilizing a series of 3 stages that can either be categorized as either light-dependent or light independent reactions. By testing the effectiveness of these reactions within chloroplasts, the ability of spinach to thrive in varied temperatures was determined. The hypothesis, which predicted the decrease in efficacy and productivity of the photosynthesizing activity in spinach leaf chloroplasts placed in …show more content…
While S. oleracea can tolerate a relatively high range of growth temperatures, it generally thrives in cooler environments of approximately 20ºC. Environmental temperatures deviating either far below or far above this optimum will see a decrease in overall photosynthetic activity and productivity. Global warming, or the systematic increase in standard air temperature globally, is rapidly becoming an increasingly urgent topic of international concern. While the progression of global warming, and consequently, the greenhouse effect has, and will continue to place a wide range of impacts on both our planet and society as a whole, its impact on agriculture cannot go unnoticed. [Hikosaka et al.: 2005] As spinach is heavily consumed as well as a global staple, it is important to determine the effects of potential environmental change on its photosynthesizing capabilities, and ultimately,

    In this experiment, the effect of climate change on Brassica Rapa will be tested. The Brassica Rapa plant is a member of the cruciferae family, or mustard family. The flowers on the plant are in the shape of a cross, which is why it is named crucifer (CFIA 2014). The brassica varieties are important to the canola industry, for they contain less fiber and more oil and protein than traditional canola (Stringam et al. 1974). These characteristics are vital for canola to be more competitive in the oil industry (Bell 1993). Brassica species also show their use and importance in that they have been developed accordingly, based on their conditions, for…

    More specifically, however, this experiment focused on the photo part of photosynthesis, or the light dependent reactions in chloroplasts. Light dependent reactions require the presence of light to function, so that this light can be taken to create ATP and to reduce NADP+ to NADPH. Consequently, light dependent reactions shut down in the absence of light, thereby stopping the production of ATP and NADPH (Sadava et al. 2012). With this information, an experimental hypothesis can be formed that the presence of light will cause the redox activity of the spinach chloroplasts to increase, while the absence of light will cause this activity to decrease. One possible null hypothesis could be that there will be no significant difference in redox activity between spinach chloroplasts that are under light and in the dark. Therefore, the alternative hypothesis must be that there will be a difference in this activity between the two groups of chloroplasts. To test these hypotheses, chloroplasts were extracted from spinach leaves in order to create enriched chloroplasts, which were a vital…

    Introduction: In this experiment, the goal was to determine the answers to two questions: (1) Do non germinating peas experience Cellular Respiration? And (2) does temperature affect the rate at which a pea undergoes Cellular Respiration? The original hypotheses were: “Cellular Respiration will occur at a faster rate in Germinating peas than in non-germinating peas” and “A lower temperature will slow the rate of Cellular respiration”. Cellular Respiration is essentially the “opposite” of photosynthesis; in other words, the equation is made up of the same parts as photosynthesis, but the “parts” are set up in reverse order as shown:…

    DPIP will be used to determine the rate at which the cholorplasts are being reduced. The spectrophotometer will establish the wavelength of light that penitrats the chloroplast solution in turn determining the amount of electrons reduced. In the dark reactions, the spectrophotometer will measure the amount of light passing through a darker solution of DPIP and chloroplasts. In the light reactions, the lighter solution, caused by reduction of the chloroplasts, will allow a larger amount of light to pass through to the photocell of the spectrophotometer. Thus, the spectrophotometer will prove wheter the light or dark reactions affect the rate of photosynthesis in chloroplasts. We will also be using a reference solution made of water, phosphate buffer, and active chloroplasts. The purpose of this solution will be used to set the transmittance level for the experiment. The control solution, which is different than the reference solution, is comprised of water, phosphate buffer, and DPIP. It will be…

    Data Analysis: Graph 1 indicates the relationship between the dependent and the independent variable to be; as the concentration of sodium bicarbonate in the solution submerging the leaf discs is increased, the average rate of photosynthesis of the leaf discs increased in a linear trend. As it is the sodium bicarbonate which decomposes into carbon dioxide necessary for photosynthesis, it is reasonable to consider from Graph 1 that as carbon dioxide concentration of the solution increases, the rate of photosynthesis will also increase in a linear trend. Carbon dioxide concentration is shown to be directly proportional to rate of photosynthesis ([CO2] ∝ rate of photosynthesis). The line of best fit in Graph 1 illustrates that at 1% sodium hydroxide…

    Four months ago in the small town of Newtown, Conn. twenty first graders and seven adults were shot dead by a mentally challenged teenager who committed suicide right after. Earlier that day, he also killed his mother. A NRA member, who for some reason had military weapons at her house. The town lost some of their children, but America as a whole grieved. Not too long after, people started pointing fingers. Who’s to blame? The NRA? The mentally challenged? The school system , who did not have an armed police officer onsite? The mother who had guns at home? Video games? The government for not having strict gun laws? It’s a delicate situation and it is very hard to hold someone responsible. But one thing is for sure; when the worst things happen, in order to comprehend the facts, people always need someone to blame.…
