Photosynthesis & Solar Photovoltaic Technology
hat is photosynthesis and how does photosynthesis work? How is process of photosynthesis linked to photovoltaic technologies? How are they the same and how are they different? This paper will delve into those issues and provide answers to the questions.

Photosynthesis is the process in which green plants create their own food thanks to sunlight shining on them. Animals eat other organisms for their nutrient intake, but plants make their food thanks to the fact that they have chlorophyll. Chlorophyll is the pigment that creates the green color in plants and it "…captures the Sun's energy and uses it to make sugars out of carbon dioxide from the air and water" (Ohio State University, 2008). The sugars are vital to the process because they provide fuel for the roots of the plant, the stems and leaves of the plant, and allow the plant to continue to grow.….

However, unlike chlorophyll, silicon cannot be used for energy-generation in its raw state, and must be processed by humans. Silicon is favored "because it remains a good conductor of electricity even after it has been heated. In order for silicon to be used for solar cells, it must be heavily heated to separate it from oxygen so that it can be further processed" (Stier 2009). Although solar energy is widely touted as a 'green' technology, the actual manufacture of silicon cells is relatively labor-intensive and results in the burning of a considerable amount of fossil fuels. In contrast, the photosynthesis that takes place in plants is truly 'green' (no pun intended). "Plants are able to create their 'solar panels' relatively inexpensively, so much so that in seasonal climates they regularly shed their leaves and rebuild them the following year using a clean, low-power energy source; out of locally-available and….

Conclusion

An autotroph is an organism that uses sunlight and/or other inorganic features of its environment to create/convert the energy it needs in order to survive, such as most plants including the spinach that was used in this experiment (Kent, 2000; Dalton, 2012). A heterotroph, on the other hand, is an organism that needs to consume other organisms in order to meet its internal energy needs; humans are one obvious example of autotrophs, as is almost every member (perhaps every member) of the animal kingdom (Kent, 2000; Dalton, 2012). In….

Photosynthesis is a process in plants, algae, and some prokaryotes, that coverts solar insulation into chemical energy stored in glucose or other organic compounds. Photosynthesis occurs in slightly different ways in higher plants relative to photosynthetic bacteria. Photosynthesis is an important process because it harnesses the sun's energy into utilizable forms of energy on earth. Most biological organisms such as animals and fungi are unable to directly use light energy to power biological processes such as active transport, cell division and muscle movement. ATP is used to power these processes. Photosynthesis converts light energy into chemical energy in the form of glucose and then the process of cellular respiration converts energy in glucose to energy in the form of ATP which is ultimately used to power biological processes. The energy produced by photosynthesis forms the foundation of virtually all terrestrial and aquatic food chains. As a result, photosynthesis is the….

Photosynthesis is critical for the survival of all life on earth. The process of photosynthesis within plants consists of two processes, one which begins with energy from the sun in the form of visible light, and another which is light-independent and capture carbon dioxide for glucose production (Audesirk, Audesirk, & Byers, 2008).
Plants are green because they absorb the red and blue wavelengths of visible light, thereby reflecting the color green (University of Idaho, 2008). In the light-dependent phase of photosynthesis, oxidative phosphorylation occurs when light pigments are absorbed by plant chloroplasts and converted into ATP and NADPH in the thylakoid membranes (University of Idaho, 2008; Audesirk, Audesirk, & Byers, 2008). The light-independent phase, also known as the carbon fixation reactions, uses the ADP and NADPH to produce glucose from fixed and reduced carbon dioxide and the enzyme uBisCo (University of Idaho, 2008; Audesirk, Audesirk, & Byers, 2008). Water is necessary….

Photosynthesis
Why There Would Be No People Without Plants.

Plants play a crucial part in the life circle of animals and human beings and their importance in life cannot be undermined, they contribute to the global food chain as the primary source of food and are the reason that life exists. The lives of all the living organisms and human beings are dependent on plants, hence an explanation as to why plants are placed at the bottom of the food chain. Apart from the plants, no living creature can derive or make its own food, it is only the plants which are self sufficient and can manufacture their own food for survival (Anne, 2007).

Plants through the process called photosynthesis take in water, carbon dioxide and light to produce sugar which is in form of glucose and release a lot of oxygen into the air. Photosynthesis takes place in the chloroplasts using the….

Color

Discussion of Graph:

The graph tracks the different heights. Blue light shows better results than red or yellow light. Blue is part of the white light spectrum, so it is understandable that the results would be similar. hite light had to be used as a control factor

Conclusion

Soybean development under blue light was similar in several respects to that of shaded plants. It was consistent with an important role in the regulation of growth. Therefore, soybeans from blue light conditions partitioned relatively more growth to leaves than red and blue only. The results confirm the general hypothesis. Experimental design was a key factor in the success of the scientific inquiry due to control and uniformity. The investigation can be replicated due to the ease of acquisition of the experimental materials and the uniformity of conditions. The replication of an experiment is an evaluation of validity because it eliminates chance occurrence as….

Photosynthesis is the process by the help of which plants make their own food by capturing the solar energy. Solar cell as compared to the plants coverts the sunlight into electric energy in order to be used by the human beings. This paper aims to highlight the differences and similarities between a plant cell and a solar cell in addition to the application of laws of thermodynamics to each system.
Laws of Thermodynamics

In the case of photosynthesis and the solar cells, three laws of thermodynamics are applicable. According to the first law of thermodynamics, energy, or mass cannot be created nor they can be destroyed (ana, 2008, p. 67). The first law of thermodynamics is fulfilled by the plant cells as no new energy or mass is being created but solar energy is being converted into chemical energy or electric energy in the case of solar cells. Second law says that….

Excited electrons are captured by primary electron acceptor of the Photosystem II electron transport chain. This system also splits molecules of water into 1/2 O2, 2H+ and 2 electrons. This process is termed noncyclic because the electrons that pass through here do not return to the original photosystem. Photolysis, an ultraviolet light-mediated nonenzymatic reaction, generates H+ ions replacing those lost in the photosystems. This is explained through the chemiosmosis theory which states that as electrons are transported to the electron transport chain some energy is released which are used to pump protons across the thyalakoid membrane from the stroma of the chloroplast. This produces a proton gradient or what is called, proton motive force. This same force is used to generate ATP from ADP and Pi.
What are the roles of NADH and NADPH in cellular respiration and photosynthesis?

NADH, together with FADH2 is produced from three processes, namely: glycolysis, fatty….

Cellular espiration and Function
Every living organism needs energy to survive since all cells require energy in order to perform the necessary biochemical reactions that sustain homeostasis within an organism. Cellular respiration and photosynthesis can be described as processes through which living organisms gain and utilize energy. However, photosynthesis is the process through which plant cell obtain and utilize energy from the sun and make it available to all living things. During this process, plants capture energy from the sun and transform it into chemical energy. Moreover, photosynthesis entails combining carbon dioxide and water into simple sugars like glucose through the use of energy from the sun (Editorial Board, 2012, p.51). In contrast, cellular respiration is the process through which cells are allowed to tap into the energy stored during photosynthesis. This process entails chemical reactions that break down glucose before converting it into a huge amount of ATP. The ATP….

Cellular respiration is the process whereby living cells gain energy through the oxidation of organic substances, which maybe, carbohydrates, proteins or fats. The preferred source of nutrient for most cells in the body is glucose. (ussell, 2004)
The first step in cellular respiration is glycolysis. The end product in this stage of respiration for cells with mitochondria and an adequate supply of oxygen is Pyruvate. This is a series of ten reactions that yields two NADH and two ATP molecules. Oxygen is required here to re-oxidize the NADH formed during the oxidation of glyceraldehyde 3- phosphate. This is called aerobic respiration. Alternatively, in cells with decreased or absent oxygen molecules, glucose is converted to pyruvate, which is reduced to form NADH to form lactate. This is called anaerobic glycolysis since there is no net formation of NADH. Anaerobic respiration occurs in oxygen deprived cells and in red blood cells because they….

The hypothesis here is that it is the quality of the light, not the quantity of the light that makes a difference, and having a lot more light will not necessarily make photosynthesis occur any faster.
Discussion

With an experiment like this there is always room for error. Measurements taken incorrectly is the biggest problem, because there are multiple steps to be taken each time the light source is moved, and it is very important to ensure that this is being addressed correctly. The quality of the plant and its health could also affect whether it produced photosynthesis rates that are appropriate and generalized for its species, as well. These are variables that can only be controlled to a certain degree and, as such, have to be accounted for.

How do different cultures and age differences affect workplace relations?

Just like no workplaces project is alike, no project team is alike in terms of the background and values of the individuals that make up the team. All too often it is tempting to assume that our personal values are universal values. Something as simple as personal space can feel very intuitive, even though what is considered the 'correct' distance is actually culturally determined. In many societies, such as Mediterranean cultures, a very close distance between two conversing parties is normal. In other cultures, a respectful distance is demanded, particularly between superiors and subordinates. A Japanese-American manager might find his Italian-American employee to be excessively familiar and confrontational, simply because the man stands too close to him and….

The Golgi receives new proteins and lipids from the ER, finishes them up, addresses them and sends them to their final destination. In this way, the Golgi could be the postal service of the city. Lysosomes get rid of unusable waste within the cell and recycles those materials that can be reused, making it the recycling and garbage center of the city. Mitochondria are where ATP, the main energy molecule, is made. It could be considered the city's power plant. Then we have the cell's cytoskeleton, which gives the cell its shape, strength and its ability to move. It can be looked at as the roadways and bridges of the city.

The work of Manahan (2005) explains that there are four traditional environmental spheres including the hydrosphere, atmosphere, geosphere and the biosphere. It is related however, that a fifth sphere should be included and that is the anthrosphere, which consists of "the things humans make and do." (Manahan, 2005) The atmosphere is reported as a very thin layer compared to the size of Earth, with most atmospheric gases lying within a few kilometers of sea level. The atmosphere serves a vital protective function in that it absorbs highly energetic ultraviolet radiation from the sun that would kill living organisms exposed to it.

A specifically important aspect of the atmosphere is that the atmosphere serves a vital protective function in that it absorbs highly energetic ultraviolet radiation….
