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 ...

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).
When light energy is converted into chemical energy due to the presence of chloroplast, the specialised cell structure found in plants, can be described as photosynthesis. During the day, the input includes carbon dioxide, water, and light, whilst the output consists of glucose and oxygen (Encarta Encyclopaedia 2000). At night, photosynthesis stops and plant-cells consume oxygen as animal cells. Photosynthesis is the process in which plants, algae and photosynthetic bacteria converts sunlight into chemical energy through the absorption of wavelengths. The processes of photosynthesis occur in two stages of Light reaction (Light dependent) and Dark reaction (Light independent). Light reaction results in a series of electron transfers resulting
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 = =
Photosynthesis and cellular respiration help sustain life on planet earth as both are metabolic processes in their own way. Photosynthesis is the process by which plants and other organisms use energy from the sun to form glucose from water and carbon dioxide. From there, glucose is then converted to ATP by way of cellular respiration. To convert nutrients that are biochemical energy into ATP, a process such as cellular respiration that has reactions needs to take shape in the cell of an organism, releasing waste products at the same time. For the continuous energy cycle that tolerates life on Earth as we know it Photosynthesis and Cellular respiration very essential. They have a few stages where energy and various connections occur within the eukaryotic cell. Cellular respiration takes place in the lysosome, an organelle that is found in the cytoplasm of eukaryotic cells. It uses enzymes to break down biomolecules including proteins, nucleic acids, carbohydrates, and lipids. Photosynthesis involves the chloroplasts, which contain pigments that absorb the sunlight and then transfigure them to sugars the plant can use. Those specific processes are crucial in how far and diversified evolution has
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.
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 consists of two things, Light Dependent Reactions and Light Independent Reactions which both take place inside of chloroplast cells. Photosynthesis is the process in which autotrophs, organisms that make their own food, use sunlight to process their own food. Water, sunlight, and oxygen are all substances that undergo change during photosynthesis and oxygen and glucose are the products of the reactants. Chloroplasts, the cell where photosynthesis takes place, contains thylakoids, the granum, and the stroma.
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.

According to scientists, photosynthesis is “the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.” ("pho•to•syn•the•sis,")
