The Effect Of Temperature On Rate Of Photosynthesis Of Pondweed Plant Coursework

The Effect Of Temperature On Rate Of Photosynthesis Of Pondweed Plant - Coursework Example Literal meaning of photosynthesis is â€Å"to put together by light†. It is a process that involves capturing sunlight, in the presence of chlorophyll, CO2, water, and then producing starch and oxygen. This starch is then used by the plants either to produce energy, for storage, or to build them into a complex material and then producing starches, oils and proteins. Starch is the best way to store carbohydrates as it is compact and is easily broken down in the body. During the process of photosynthesis plants fix environments CO2 and release oxygen, which is essential for entire living beings for survival. Thus, more than 80% of plant material is synthesized by photosynthesis including respiration process also depends on its byproducts. Chlorophyll is the chemical, which traps light energy and then uses it to synthesize carbohydrates. It acts as catalysts to speed up the process of reaction. Chlorophyll is present in the chloroplasts of the palisade layer of leaves. The equati on for photosynthesis is: 6CO2+6H2O => C6H2O6+6O2 +energy Photosynthesis involves trapping of CO2 from the environment in the presence of Chlorophyll and the sunlight. If a light source is placed near the pondweed plant that acts as sunlight, then the plant will release more oxygen due to splitting of water molecule into hydrogen and Oxygen molecule. The Hydrogen molecule that is released in the process will then combine with the CO2 and produces carbohydrates. This process again gives off more oxygen. The whole process needs to be catalyzed by enzymes to speed up the reaction. Photosynthesis is a two phase procedure. Stage one is light reliant and it captures sunlight to manufacture high energy molecule. In the second phases, which are light free reactions, these molecules are used to incarcerate CO2 and convert them into originators of carbohydrates. There are various limiting factors that affect the rate of photosynthesis. Most important factor is the presence of CO2 in the envir onment i.e., 0.03% to 0.04%. Only at a certain rate can a plant takes up CO2 and proceeds with photosynthesis. Light intensity will also affect the rate as well as temperature. In laboratory experiments, volume of oxygen released per minute is used to determine the rate of the process, and this in turn can be used as the source for determining the effects of limiting factors (Kent, 2000). The law of limiting factor states that, â€Å"When a process depends on more than one factor to be favorable then its rate is limited by the factor at its least favorable value. For a process to go at its maximum rate, all factors need to be at an optimum stage.† Measurement of photosynthesis rate is required to determine the limiting factors that can affect productivity of the process as well as its response to environmental stresses. Most of the measurement techniques being used today involve the gaseous exchange of the plants as an indicator for the rate. Chemical pathway of intake of CO2 and water discharge is the same and hence these two pathways are involved in measurement of photosynthesis through stomata conductance and transpiration method (MILLAN, GUEVARA, TORRES, OSORNIO, 2009). These days modified methods are being used to conduct the analysis, which increases the precision and accuracy of the results. The purpose of this experiment is to determine the effect of temperature on the photosynthesis of pondweed plant. Basically, temperature does not pose an enormous effect on the rate of photosynthesis individually; it only affects the speed of the process by affecting the rhythm of chemical responses in the plants. This is because photosynthesis is a

Training needs analysis - Essay Example Training needs analysis involves assessing the needs of the Hospital Services Advisors, through a training programmme and evaluating the training needs analysis. The organisation which will be the focus of such a process is Ramsay Health Care UK. RAMSAY HEALTH CARE UK The founding of Ramsay Health Care (RHC) was back in 1964. The company has developed, and has over 117 hospitals. Furthermore, it has day surgery amenities in France, Australia, Indonesia, and United Kingdom. This made the organisation assume the status of a global private healthcare operator. In England, the company obtained Capio UK and its group of hospitals in 2007. By September 2010, RHC had employed more than 3500 employees, making it the top health care providers in the UK. This achievement provided a solid foundation for expansion. The company benefits from its established trade name because of its wide spread network. It competes effectively with regional players. Currently the RHC is in a lasting affiliation with the National Health Services (NHS), where it provides surgical and diagnostics services to both private and self-sponsored patients. In the year 2010, RHC had a 10% augmentation of revenue after getting revenue of 350.2 million in the 2009 financial year. During the Medibank Private Menders’ Survey, RHC was ranked among those who had the top honors. Moreover, RHC was also among the five finalists of the best Health and Wellbeing Strategy in the Australian Human Resource Award. Furthermore, it has an excellent ability to satisfy its customers’ needs. For this reason, it has constantly emerged the top three after rating the two hundred service companies in the private and public sectors. There has been an escalation of birth rates, growth of outpatients’ treatment and the increase of the ageing people. Consequently, the economic environment and the demand for private health care are steadily escalating. This forces the RHC to expand its hospitals in the UK so as to succeed in catering the needs of the public. Additionally, RHC has successfully maintained satisfaction for its staff by ensuring that the proper work place health and protection risks are on check. Consequently, RHC has had a reduction of the time wasted because of injuries. The aim of RHC is to be at the top in offering the highest quality clinical services among the private healthcare hospitals. Furthermore, the organisation responds to the requirements of its patients by providing the best customer services. For them to meet their objectives, the RHC conducts an operation measure every year toward improving the patients’ experiences, and clinical effectiveness. Additionally it acknowledg es the importance of investing in human capital. Therefore, this has been the reason for its current achievements and developments. Moreover, the RHC offers scholarships to its staff who wishes to further their studies. For example, the company recently offered sixty thousand dollars for the staff to pursue postgraduate at its will. The strengths of the organization incorporate its wide network since it has several outlets that offer the necessary services to the clientele base. This enhances its ability to compete within the health industry. Furthermore, its personnel are well versed with operational processes making it simple to embrace emerging technologies that enhance their skills. An additional strength pertains to the organization’s ability to attain increased revenues as illustrated in the financial outcomes. The most significant weakness arises from the inability to determine the patient’
