How the Photosynthetic Process Works in Trees

How the Photosynthetic Process Works in Trees Photosynthesis is an important process that permits plants, including trees, to use their leaves to trap the suns energy in the form of sugar. The leaves then store the resulting sugar in cells in the form of glucose for both immediate and later  tree growth. Photosynthesis represents a beautifully wonderful chemical process in which six molecules of water from roots combine with six molecules of carbon dioxide from the air and creates one molecule of organic sugar. Of equal importance is the by-product of this process- photosynthesis is what produces oxygen. There would be no life on earth as we know it without the photosynthetic process.   The Photosynthetic Process in Trees The term photosynthesis means putting together with light. It is a manufacturing process that happens within cells of plants and within tiny bodies called chloroplasts. These plastids are located in the cytoplasm of leaves and they contains the green coloring matter called chlorophyll. When photosynthesis takes place, water that has been absorbed by the trees roots is carried to leaves where it comes in contact with the layers of chlorophyll. At the same time, air, containing carbon dioxide, is taken into leaves via leaf pores and exposed to sunlight, resulting in a very important chemical reaction. Water is broken down into its oxygen and nitrogen elements, and it combines with carbon dioxide in the chlorophyll to form sugar. This oxygen released by trees and other plants becomes a part of the air we breath, while the glucose is carried to the other parts of the plant as nourishment. This essential process is what will make of 95 percent of the mass in a tree, and photosynthesis by trees and other plants is what contributes nearly all the oxygen in the air we breathe.   Here is the  chemical equation for the process of photosynthesis: 6 molecules of carbon dioxide 6 molecules of water light → glucose oxygen The Importance of Photosynthesis Many processes occur in a tree leaf, but none more important than photosynthesis and the resulting food it manufactures and the oxygen it  produces as a byproduct. Through the magic of green plants, the radiant energy of the sun is captured in a leafs structure and made available to all living things. Except for a few kinds of bacteria, photosynthesis is the only process on earth by which organic compounds are constructed from inorganic substances, resulting in stored energy.   Roughly 80 percent of the earths total photosynthesis is produced in the ocean. Its estimated that 50 to 80 percent of the worlds oxygen is generated by ocean plant-life, but the critical remaining portion is generated by terrestrial plant life, particular the earths forests  Ã‚  So the pressure is constantly on the terrestrial plant world to keep up the pace. The loss of the worlds forests has far-reaching consequences in terms of the compromising the percentage of oxygen in the earths atmosphere. And because the process of photosynthesis consumes carbon dioxide, trees, and other plant life, are a means by which the earth scrubs out carbon dioxide and replaces it with pure oxygen. It is quite critical for cities to maintain a healthy urban forest in order to maintain good air quality.   Photosynthesis and The History of Oxygen Oxygen has not always been present on earth. The earth itself is estimated to be around  4.6  billion years old, but scientists studying geologic evidence believe that oxygen first appeared about 2.7 billion years ago, when microscopic cyanobacteria, otherwise known as blue-green algae, developed the ability to photosynthesize sunlight into sugars and oxygen. It took roughly a billion more years for enough oxygen to collect in the atmosphere to support early forms of terrestrial life.   It is unclear just what happened 2.7 billion years ago to cause cynobacteria to develop the process that makes life on earth possible. It remains one of sciences most intriguing mysteries.

101.Should talking and texting on a cell phone without a hands-free Essay

101.Should talking and texting on a cell phone without a hands-free device while driving be illegal - Essay Example More alarmingly, recent years of the road safety issues are derived from the mismanagement of communication devices during driving. A careless and distracted driving practice associated with talking or text messaging while the vehicle governance is on the rise in every part of the world. More noticeably, use of handheld devices during driving is more dangerous than permissible levels of drunk driving because the former holds the preoccupation of the driver indulging in impulsive variations. Thousands of lives are lost and many more are left permanently disabled due to the negligence of drivers of public transportation particularly. At this wake, it is essential to make an over view of the impact of the culpable practice of careless driving and raise an alarm in the minds of people about the peril closely following it. Severe violations of driving ethics from drivers cause damage to life of people from utter carelessness. In an accident, the impact of the negligence of one drover is born by either party involved and usually, the lighter vehicle gets most of the reward of the evil. As Barrouquere (Sep 14, 2011) reports, in Kentucky, a tractor-trailer crash on a van claimed nine lives on the spot in Interstate 65 on 26th March, 2010 – the reason was that the truck driver had just made and outgoing call that lasted for a second when the truck hit the van. The Kentucky accident alerted the authorities which came forward with bills banning the use of hand held communication devices, especially mobile phones during driving. Presently, there are many regulations of the use of handheld devices while driving but most of them are limited to marginal amount of penalty that prove insufficient to curb this problem. The identified reasons for increasing car and truck accidents reveal the role of employers, parent and consignees who make frequent and unexpected calls to the drivers of both commercial and private vehicles. At the moment,

International Production and Trade Essay Example | Topics and Well Written Essays - 750 words

International Production and Trade - Essay Example The author in the chapter sought to identify the basic features and issues forming the international production and trade structure. While discussing the changes taking place in the production of goods, the author uses the case of Thomas Friedman to explain the post-world war II changes that have taken place. Technology is arguably one of the most significant steps that man has discovered so far. As such, it has revolutionized both the production process and the communication channel. While the internet connects people in a previously un-imaginable way, new products such as cars and clothes go through mass production. Another notable change in the production process is the level of fragmentation and specialization taking place. With the increased level of interdependence between different countries and regions around the world, production methods have spread in all parts of the globe. Statically, the World Bank demonstrated the effects of this growth and increase in production throug h the 2005 world’s gross domestic product, which was approximately $44.3 trillion. Of this, 78% came from the developed countries, while the middle and low income, countries contributed only 22 percent. Five years earlier, the level of production was fives lower as it was in 2005. McGrew, an expert observes that there have been changes in the trends of FDIs, which have subsequently contributed to the capital mobility. In this mobility, firms now migrate from the industrialized countries and set up production plants in less developed countries due to labor issues as well as environmental issues. International trade, which is trade that takes place between different countries, help in the unification of countries. Since trade ties countries together, it generates significant political, economic, as well as social interdependence between countries. As such, many states use it as a means of gathering income, opting to regulate it in an effort to safeguard their interests. The int ernational trade structure, by pulling international leaders, IO and the NGO officials, pulls three perspectives of trade at the same time. Despite their conflicting arguments, these perspectives have contributed to the understanding of the development of trade in the international front. International trade rules came into effect in the sixteenth through the eighteenth centuries. Tariffs and quotas existed back then, as there was a restriction of importing intermediate goods. This aimed at protecting local industries from unfair competition. One of the international trade policies launched in the eighteenth century advocated for a laissez-faire type of policies. Proposed by Adman Smith and David Ricardo, the liberal trade policy still applies in the case of the Britain markets. These were the developers of the comparative theory, which advocated for opportunity cost of production. Proponents of opportunity cost theory pointed out that for a country to produce a particular commodity ; it had to forego a particular commodity that was rather expensive to produce. As such, introducing trade restrictions was an unjust way of treating other nations. However, the mercantilists challenge the arguments of comparative advantage, even currently. They argue that states can

Improving Life in the United States Essay Example | Topics and Well Written Essays - 750 words - 1

Improving Life in the United States - Essay Example One of the major concerns of America today is the growing number of obese people. Children are not exempted from such and this calls more attention to how American families are raising their children. Doctors and researchers all agree that American diet have drastically changed, relying on easy to prepare foods or the readily available victuals from fast foods. They are now promoting changes in how Americans eat, going back to how our ancestors, decades ago, ate. On a parallel, as this problem is being resolved, similar attention is solicited to a much wider scope of concern. The production and consumption of local farm products is advertized at a higher level because of its effect on the various aspects of American living. First, from health advocates who suggest that home-grown fruits and vegetables are far healthier because they are locally available while they are still fresh, with more nutrients as compared to imported products that have undergone various stages of preservation. Secondly, by environmentalists who suggest that local production and consumption will create a tight-knit interconnection between producers and consumers, enabling accountability between them (Morris, 641). Such a situation will create awareness about how the products are produced and transported and therefore will demand high standards of maintaining quality services from farmers and producers. Such awareness in turn, will help consumers appreciate the efforts of farmers and producers. Thirdly, from economists who argue that buying locally grown food is not only good for local economy but on a global level as well. Although there are beliefs that local production will kill developing countries’ economies especially those who rely on exportation for their economic growth, Morris says otherwise. To prove his point, he cites CARE, a non-profit organization that works to fight global poverty which refused to accept tens of millions of dollars in federal money for food aid in Af rica, arguing that such help undercuts farmers, making their situation worse and not better. He thus suggests that local production to make Africa self-sufficient is rather the solution to their problem and not reliance on exportation or help extended by successful countries (642). The environmentalist’s perspective mentioned earlier reflects in part the argument of Al Gore in his Nobel Lecture in 2007. He informed the American people that on the day he delivered his lecture, 70 million tons of global-warming pollution has been dumped and a larger amount will be dumped again the next day (721). If such an increase has been constantly growing for the past five years, imagine how large both American producers and consumers contributed to such pollution. The lack of accountability and awareness in the production and consumption of imported goods surely is a great factor to this global crisis. Therefore, in response to Al Gore’s call for the Americans to forge a united eff ort, with great individual involvement, everyone should become aware of this impending crisis that might dim the future of the next generation. Being accountable, this generation should act and, act quickly, together (724). The modern American lifestyle has improved a lot when one evaluates on the basis of technological advancements. However, there is no denying that such achievements have destructive consequences not only individually and locally but also globally. The fast-paced modern

Fighting Against Animal Cruelty English Literature Essay

Fighting Against Animal Cruelty English Literature Essay Fighting against animal cruelty is something Im particularly passionate and sensitive about. Some people may argue with me and tell me Im over reacting. However, I couldnt actually be bothered! People like myself are what our world needs to protect these creatures with no voice. In China dog control officers may kill any unaccompanied dogs on sight. There are no government supported charitable organisations like the RSPCA, which monitors the cases on animal cruelty. Animal abuse is on the increase in South Africa, and many of the perpetrators are young children. In 2006, three Randburg school girls set alight a mouse and watched as it burnt to death. They recorded the incident on a cell phone and their laughter is clearly audible as they enjoy the spectacle. Issues like THESE make me SO upset and angry! It kills me to see how people especially girls who are nurtures, can take it upon themselves to act this way! This is why taking care of or helping abused and abandoned animals is my most essential goal in life. My passion in life is to live in Paris in some little attic in someones house, and every morning wake up, set up my canvas and paint on the sidewalks. Ive wanted to do this since I was a little girl. Watching Aristo Cats and 101 Dalmatians has opened my mind to bigger things, and has showed me how free artists are in Europe. I want to paint and draw pieces that arent going to be assessed or moderated by people who are going to bring me down. I want to paint how I want to and what I want to, and then selling my artworks to people around the world and HOPEFULLY making money to open up an animal shelter or maybe more. Not only will I provide a home for all these poor lost and neglected animals; Im also going to go out and fight for them by being a part time animal cop. I can sit for hours and bawl my eyes out while I watch animal cops SA, MIAMI, HOUSTEN and PHOENIX on Animal Planet. This is what made me realise what my ambition was. Friends and family will tell you that I would sacrifice my life for an animal. And to you that may sound ridiculous, however it is the truth. Ive actually had two occasions when I felt like an animal cop. One of them was when I was in town one morning when the sun was blistering hot, I felt like I was baking! While walking along the pavement, I came across a puppy curled up in the corner of an open van. She had no water, no food and no shelter. This made me SO mad! I went back without my mum and confronted the man in that uncontrollable state. My mum was too scared to do anything about it so I stayed mad with her until she had to call my dad, who then told me to go to the nearest police station. This fortunately for me was across the road. I laid a charge by myself and those men were charged with animal abuse. After attending the circus 3 times when I was a little girl, Ive never been back since. Seeing animals being ill-treated in such an immoral and horrible way upset me terribly and my dad and I made a pledge that wed never go back to the circus again. Small things like this make a HUGE difference to our society and our world. The second incident when acting as an animal cop was when I went to my friends house to see her new kitten on a rainy night. Before I got there I had assumed that she was looking after this poor kitten that was found in the gutter. However, she was dumped in the Wendy house with no food, no water and no litter box! I found her behind some tools took her into the shower and washed her off all that dirt and grime. Shes now, living at home, with me. Her names Piglet because her nose is like a pig and she EATS like her pig! I d like to add that my cat has a bit of an identity crisis as she does no know whether shes a cat or a dog! She plays fetch with a rolled up cling wrap ball. When you throw it for her she skids and slides after it and brings it right back to you and drops it into your hand for more rounds. She sits in the shower with me because she LOVES WATER! She even plays catchers and hide and seek with me. I need say more. My mum told me that I was the animal farms weekly visitor without fail. Animals arent there for you to take your frustrations out on or to just feed them and leave. However they WILL sit there and listen to you when youre mad. upset and have no one to talk to. Whether you pass over that eagerly awaited walk in the park for the following day†¦ they still forgive you and will ALWAYS come running back into your arms. I hope that every one of you pay special attention to your animals, because just as much as they love you, they want you to love them back the exact same way without the voices to tell you so†¦

Misrepresentation of Love Essay -- Analysis, St. Augustine’s Confessio

â€Å"Our hearts find no peace until they rest in you† (21). The return to God, the means of doing so, and the manners by which man is turned from him in the first place, are central themes in St. Augustine’s Confessions; a historical work serving as confession, praise, and examination of faith. Autobiographical in nature, Augustine’s work retells the story of his life and of his spiritual journey in retrospect, considering each event and its importance to the larger framework of his religious philosophy, a result of the merging of Neo-Platonist thought and Catholic theology. Through this fusion, Augustine is able to reconcile God and â€Å"evil,† make a distinction between the physical and spiritual realms, and lay out his views on how one can come to know and love God the truest sense possible; how one returns to him. One of the main problems Augustine had as he began his examination of spiritual matters was the apparent existence of evil. Augustine was unable to reconcile the notion of God as unchanging and all-powerful with the evil that he saw in the world. If God was indeed omnipotent and the creator of all, how could evil exist if God did not have a hand in its making? Thus in his earlier years, Augustine fell in with the Manicheans, who held that God was not omnipotent, but rather in constant battle with evil and opposite force. Such ideas of evil and of God’s connection to the physical realm drove Augustine further from God. Fortunately, Augustine became dissatisfied with the Manicheans, whose flowery words proved to lack substance, and whose cosmological predictions proved less accurate than science and frequently a product of coincidence. Even after rejecting the dualism of Manichean thought, Augustine struggled to re... ...to be God-like, or even simply closer to God, being grounded in the tangible world, attempts are frequently and inappropriately invested in the physical realm, ultimately driving one further from God. Most sins are really just misdirected attempts to be like God. â€Å"Sloth poses as the love of peace...Extravagance masquerades as fullness and abundance†¦The spendthrift makes a pretence of liberality...The envious struggle for preferment†¦Grief eats away its heart for the loss of things which it took pleasure in desiring, because it wants to be like you, from whom nothing can be taken away† (50). Though introspection, we can pull ourselves from physical matters to spiritual matters, searching the soul for an inner memory of God, and thus better serve God (and the Force). Ultimately, love is not wrong, so long as love is through God. â€Å"Love them, then, in Him† (82).
