Introduction:
Artificial photosynthesis could revolutionize our energy source and could solve the global warming crisis. Since the artificial photosynthesis is a renewable and clean energy with zero carbon dioxide emission and only harnessing the sun energy. This innovative works that mimic the process of plants by splitting the water molecules and produce products of Hydrogen and oxygen only by using the energy from the sunlight. With this the technology, it can produce products of hydrogen that can be converted into fuels that give many benefits to human for instance, transport, electricity generation and industries. In the process of artificial photosynthesis also give out a by-product of oxygen to the surrounding that reduce the level of carbon dioxide. However, there are several issues regarding this artificial photosynthesis one is the materials to manufacture it and the other one is the energy require to split the water molecules perform by this technology. Through breakthrough of advance research and nanotechnology, scientist and technologists are able to tackle these problems and make artificial photosynthesis a reality and one day could be used as an energy resources.
The comparison of artificial photosynthesis with nature.
Photosynthesis is a wonderful process that takes place in nature for examples in plants bacteria and algae. Where it capture the energy from the sun and convert (carbon dioxide and water) to chemical energy and storing it in the bond of sugar (fruits). The process of the photosynthesis takes place in the chloroplasts, specifically using chlorophyll (the green pigment. Human are familiar with the utilized the sun energy by using solar energy system ...

Conclusion:
Research in artificial photosynthesis show some significant development over the past decades in efficiency, material of catalysis which are cheaper and abundant, and also the storage of hydrogen. Artificial photosynthesis could be the holy grail of human energy resources, with is renewable resource and long term energy use. The commercial of artificial photosynthesis could be happening I the near future.
The majority of life on Earth depends on photosynthesis for food and oxygen. Photosynthesis is the conversion of carbon dioxide and water into carbohydrates and oxygen using the sun’s light energy (Campbell, 1996). This process consists of two parts the light reactions and the Calvin cycle (Campbell, 1996). During the light reactions is when the sun’s energy is converted into ATP and NADPH, which is chemical energy (Campbell, 1996). This process occurs in the chloroplasts of plants cell. Within the chloroplasts are multiple photosynthetic pigments that absorb light from the sun (Campbell, 1996).
Photosynthesis consists of the following equation: Sun light Carbon dioxide + Water = = == == ==> Glucose + Oxygen Chlorophyll Chlorophyll is a substance found in chloroplasts, found in the cells of leaves.
Experiment #1: The purpose of this experiment is to investigate the effects of baking soda and light intensity on the rate of photosynthesis of green spinach leave through the observation of floating disk.
An Analysis and Evaluation of Data from Photosynthesis Experiments Graph analysis This is my analysis for the investigation in to the affect of light intensity on the rate of photosynthesis to the Canadian pondweed, elodea. In the results the pattern is that when the light intensity is higher the readings are generally higher. On the graph the less the light intensity the lower the gradient of the curve. the equation for the photosynthesis process is; CO2 + 2H2O + Light Energy = =
So, after learning about what photosynthesis is and how it truly works is something that is remarkable and how plants are really the only living thing that uses this process. Such as photosynthesis is the process of taking in carbon dioxide (CO2), which is a gas that is exhaled from animals and goes into the air and is absorbed into a plant, water (H2O) which is absorbed through the roots of a plant or known as capillary action, sun light is absorbed through chloroplasts which contains chlorophyll or better known as the leaves of the plant. Sun light is what helps break down and rearranges the atoms of these two, which produces sugars (glucose, C6H12O6), and this is photosynthesis at its finest. With the photosynthesis process the plant can create a by-product known as oxygen gas which is released through the little pores into the atmosphere (Simon, Dickey, Hogan & Reece, n.d.). Photosynthesis is something that helps the plants to grow but it is also very beneficial to us for the fact that we need to breath oxygen to maintain our functions of life. Plants produce an abundant supply of energy that is stored because they are what I would like to call savers/hoarders. Plants store the extra energy that they produce into different things such as potatoes, carrots, and other different types of food in which we use to
The process of photosynthesis is present in both prokaryotic and eukaryotic cells and is the process in which cells transform energy in the form of light from the sun into chemical energy in the form of organic compounds and gaseous oxygen (See Equation Below). In photosynthesis, water is oxidized to gaseous oxygen and carbon dioxide is reduced to glucose. Furthermore, photosynthesis is an anabolic process, or in other words is a metabolism that is associated with the construction of large molecules such as glucose. The process of photosynthesis occurs in two steps: light reactions and the Calvin cycle. The light reactions of photosynthesis take place in the thylakoid membrane and use the energy from the sun to produce ATP and NADPH2. The Calvin cycle takes place in the stroma of the chloroplast and consumes ATP and NADPH2 to reduce carbon dioxide to a sugar.
Photosynthesis in simpler turns is the ability of a live plant to carry on its chemical process by the use of light energy. Photosynthesis can not take place when there is absolutely no light, instead it stores the light it captures during the day, and uses it when needed. Photosynthesis can take place in land plants and aquarian plants such as algae. There are many factors that influence the ability of a plant to go through photosynthesis, such as light, the color of light and amount of water and or light.
Photosynthesis is a process in plants that converts light energy into chemical energy, which is stored in bonds of sugar. The process occurs in the chloroplasts, using chlorophyll. Photosynthesis takes place in green leaves. Glucose is made from the raw materials, carbon dioxide, water, light energy and oxygen is given off as a waste product. In these light-dependent reactions, energy is used to split electrons from suitable substances such as water, producing oxygen. In plants, sugars are produced by a later sequence of light-independent reactions called th...
Energy, especially from fossil fuels, is a key ingredient for all sectors of a modern economy and plays a fundamental role in improving the quality of life in less developed economies. In 2007, India is ranked fifth in the world in terms of energy demand; accounting for 3.6% of total energy consumed, and is expected to grow at 4.8% in the future. India imports 70% of the oil it uses, and the country has been hit hard by the increasing price of oil, uncertainty and environmental hazards that are concerned with the consumption of fossil fuels. In such context, bio energy constitutes a suitable alternative source of energy for India, as large amounts of raw material are available to be harnessed.
Although Solar Energy is a flexible source of where energy could be directly or indirectly converted into forms of energy, it’s still not perfect. With its inefficiency, scientists are trying to find alternative solution to store solar cells for as long as possible. The main process of capturing solar energy happens at the nanoscale. With solar cells, it gets more efficient the tinier it gets. The converting rate of solar energy is equally price competitive as fossil fuel, with a dollar per watt of solar energy. With the help of nanotechnology, it could help raise solar energy conversion efficiency and help lower costs making it the ultimate method of raw energy conversion. To make sure the process of generating energy is kept at a low cost and energy output...
Photosynthesis is a process in which plants and other organisms convert the light energy from the sun or any other source into chemical energy that can be released to fuel an organism’s activities. During this reaction, carbon dioxide and water are converted into glucose and oxygen. This process takes place in leaf cells which contain chloroplasts and the reaction requires light energy from the sun, which is absorbed by a green substance called chlorophyll. The plants absorb the water through their roots from the earth and carbon dioxide through their leaves.

CONCLUSION With natural resources depleting, it is vital for human survival to look for alternatives, be it windmill to harness the wind energy, Solar panels to use them for heating and generating electricity etc.
This helps consumers called heterotrophs and autotrophs use organic molecules produced by photosynthesis as a building block for growth and repair and as a source of chemical energy for cellular work. (Mader, 2013) Photosynthesis produces an enormous amount of carbohydrate that humans use to convert it into coal.
An Experiment to Investigate the Effect of Light Intensity on the Rate of Photosynthesis. Introduction Photosynthetics take place in the chloroplasts of green plant cells. It can produce simple sugars using carbon dioxide and water causing the release of sugar and oxygen. The chemical equation of photosynthesis is: [ IMAGE ] 6CO 2 + 6H20 C 6 H12 O 6 + 6O2 It has been proven many times that plants need light to be able to photosynthesize, so you can say that without light the plant would neither photosynthesize nor survive.
Photosynthesis is a cycle plants go through converting light into chemical energy for use later. Photosynthesis starts in the chloroplasts, they capture chlorophyll, an important chemical needed for photosynthesis. Chloroplasts also take water, carbon dioxide, oxygen and glucose. The chlorophyll is taken to the stroma, where carbon dioxide and water mix together to make
