...Photosynthesis The sun is our most powerful source of energy, the ultimate source of energy for nearly all life on Earth. Sunlight can be used for heating, lighting and cooling homes and other buildings, generating electricity, water heating, and several other processes. Plants and certain other organisms are able to capture solar energy and carry on photosynthesis, a process that transforms solar energy into the chemical energy of nutrient molecules. Animals and plants get energy by metabolizing nutrient molecules made by photosynthesis (Mader, 2012). Most of this solar radiation is in the form of invisible ultraviolet and infrared frequencies, as well as the spectrum of visible light. But the most important use of solar radiation by living organisms is photosynthesis, the direct conversion of visible light into usable energy for plant and animal life, and oxygen to breathe. Only a vanishingly small part of the total amount of radiation given off by the sun actually reaches earth, and only a portion of that is utilized by photosynthesizing organisms (Shields and Teng, 2012). Photosynthesis is the process of producing and releasing oxygen in the air. It needs sunlight, carbon dioxide and water. During the process of photosynthesis, the plants decompose the molecules of hydrogen and carbon-dioxide into hydrogen; carbon and oxygen produce glucose which forms the source of their energy, growth and food. For plants their main source of energy is photosynthesis, which is used...

...Introducing Photosynthesis: What is Photosynthesis? Animals and plants both synthesize fats and proteins from carbohydrates; thus glucose is a basic energy source for all living organisms. The oxygen released, with water vapor in transpiration, as a photosynthetic byproduct, principally of phytoplankton, provides most of the atmospheric oxygen vital to respiration in plants and animals, and animals in turn produce carbon dioxide necessary to plants. Photosynthesis can therefore be considered the ultimate source of life for nearly all plants and animals by providing the source of energy that drives all their metabolic processes. The discovery of photosynthesis in cells began with the findings of Joseph Priestly. Joseph Priestly, a chemist and minister, discovered that when he isolated a volume of air under an inverted jar, and burned a candle in it, the candle would burn out very quickly, much before it ran out of wax. He further discovered that a mouse could similarly "injure" air. He then showed that the air that had been "injured" by the candle and the mouse could be restored by a plant. In 1778, Jan Ingenhousz, court physician to the Austrian Empress, repeated Priestly's experiments. He discovered that it was the influence of sun and light on the plant that could cause it to rescue a mouse in a matter of hours. In 1796, Jean Senebier, a French pastor, showed that Carbon Dioxide was the "fixed" or "injured" air and that plants in photosynthesis took it up. Soon afterwards...

...Monica Feggins 10/28/14 Linkage between Photosynthesis and Cellular Respiration The link between photosynthesis and cellular respiration is an inverse relationship. Each cycle depends on one another in order for the "entire cycle" to take place. The completed cycle make certain that life continues to exist on the planet. Both are necessary for living organisms. Photosynthesis is the process by which carbon dioxide is converted into organic compounds from sunlight. Photosynthesis occurs in plants, algae, and some bacteria. The process of photosynthesis is also the source of carbon in organic compounds in human bodies, as well as animals. Photosynthesis provides the oxygen for life and for the process of cellular respiration. The simplest way to explain photosynthesis is (Carbon dioxide + light energy → carbohydrates (sugar) + oxygen). Without photosynthesis, humans would cease to exist. Cellular respiration, in contrast, takes glucose (sugar) and other organic compounds oxidizing them to create carbon dioxide. Cellular respiration can be defined as metabolic reactions in organic cells which converts biochemical energy into adenosine triphosphate, better known as ATP. Cellular respiration also releases carbon dioxide into the atmosphere allowing plants, algae, and bacteria to process the carbon dioxide back into oxygen. The simplest way to explain Cellular Respiration is (Glucose + 6Oxygen --> 6Carbon Dioxide + 6Water). Photosynthesis and cellular respiration is a...

...the “body” of the organism consists of a variety of types of cells, each type with its own specialized function unlike the unicellular form. We also find colonial protist which consist of cells that are similar with similar function. Kelp a brown multicellular algae; Volvox, which is a green colonial algae and Spirogyra also a green algae with filamentous. Most unicellular are small in size but have a highly complexity level. Species such as Amoeboids and ciliates have a unique organelles that re contractile that assist in water regulation. Protist are all eukaryotes, (consist of true nucleus or membranous organelles) water based organisms. They are aerobic with mitochondria for cellular respiration and some have chloroplast for photosythesis. Most usual have an asexual life cycle reproduce or grow by mitosis, and some reproduce by meiosis and fertilization. Spore formation normlly occurs in hostile enviroment to incerease chances of survival y being resistant in adverse condition untill favourable conditions, many form Cysts such as protoazoans. Protist vary in size from microscopic algae and protoazoans to kelp that can be over 200 m in length. In this study of pritist cowdung culture i will be studying their abudance over 3 different week treatments.

...occurring on the planet. Let's see why. Let's begin with some basic questions & answers about photosynthesis. QUESTION | ANSWER | What is photosynthesis? | Photosynthesis is a chemical reaction in which light energy is converted to chemical energy in glucose. It is the means by which the energy in sunlight becomes usable to living things. Living things can eat glucose, we can't eat sunlight. | Exactly why is photosynthesis so important? | Two big reasons. One product of photosynthesis is glucose (sugar), which provides the basis for most food chains. The second product of photosynthesis is oxygen which comes in handy if your happen to be an aerobic organism that requires oxygen for survival. | Where does photosythesis occur? | This question can be answered on various levels. On the planetary level, most photosynthesis occurs in the oceans, because the oceans occupy the vast majority (70%) of the earth's surface. In terms of organisms, photosynthesis occurs in autotrophes that contain the green pigment chlorophyll. This would include the entire plant kingdom, "half" of the...

...Causes of Global Warming and its present and future impacts on South-West Western Australia Global Warming is an issue at the heart of modern civilisation. The prospect of a rapidly changing global enviroment is enough to cause considerable concern towards life on earth for future generations. Therefore it is important to understand how climate change works, what is causing the climate to change, what effects these changes are having, and how they may continue to affect the global environment. What causes the environments on earth unable to support life? What can be done about these predictions of climates in the future? How will these climate changes affect South-West Western Australia? How does climate change work? Climate change is a natural process that has been functioning on earth for billions of years, it is the regulator of the earth's abililty to support life by the cycles of The Greenhouse Effect. The Greenhouse Effect has made the earth an environment for supporting life through the cycling of energy from the sun via short-wave radiation, which heats the earths surface, then is released into the atmopshere as long-wave radiation. This cycle is made possible by the prescence of Greenhouse gases, which redside in the earths atmopshere, and absorb most of the long-wave radiation given off by the earth, with the remainder being expelled into space. This process cycles the heat from the sun around the earths atmosphere and a climate is the result, without this circulation...
