The overall goal of photosynthesis is to convert light energy from the sun into a chemical energy of sugar and other organic molecules. For example, apple trees use photosynthesis to produce both oxygen and fruit. Animal life needs oxygen…
Photosynthesis: The formation of carbohydrates in living plants from water and carbon dioxide, through the action of sunlight on chlorophyll in those plants, including algae.…
1. Form hypothesis: During photosynthesis, light energy is used to synthesize carbon dioxide (CO2) and water (H2O) into glucose (C6H12O6) and oxygen (O2). The complex series of chemical reactions is summarized by the following formula:…
Photosynthesis releases oxygen as a byproduct. The oxygen results from the splitting of water during the light reactions of photosynthesis. The oxygen released in the air can be used by organisms that respire aerobically to release energy stored in molecules, these organisms release water and carbon dioxide as a byproduct. The carbon dioxide is necessary for the synthesis of carbohydrates in the organisms.…
Wavelengths between 500 nm and 600 nm will be the least productive wavelengths in theoretical oxygen production. The four main photosynthetic pigments are carotene, chlorophyll a, xanthophyll and chlorophyll b (Light). The pigments are the contents in this experiment. We kept them cold to prevent any other reactions from occurring while in the spectrophotometer. We changed the wavelength on the spectrophotometer to see how well the light could pass through. The efficiency of the pigments are contributed to how little light travels through the tubes, otherwise, how much they absorb. We found that the pigments had a similar affect. They followed the same line and was more affective in common wavelengths. We found that the wavelengths that mimicked green light, around 520 nm and a little further, were not absorbed. Although there was some light still absorbed there was very little efficiency. Our hypothesis held precise, testing that there was little theoretical oxygen production when the pigments were given green light.…
Photosynthesis is the process whereby plants utilize C02, H2O and Sunlight to create food in the form of a sugar called glucose. As a byproduct of this reaction, the plants also release oxygen.…
While photosynthesis creates sugar with the sun's energy, cellular respiration utilizes the chemical energy in sugar to meet the energetic needs of organisms. During respiration, sugar is combined with oxygen, resulting in energy and carbon dioxide. Note that the equation for respiration is the opposite of photosynthesis, indicating the products of photosynthesis become reactants in respiration, and vice-versa.…

he process of converting light energy captured from the sun into chemical energy that can be used to synthesis glucose is called photosynthesis. This process is used by plants and other organisms for synthesis of lipids and amino acids or can be metabolized during cellular respiration to produce ATP. This process takes place in chloroplasts, which is a plastid that contains chlorophyll and involves two interlinked reactions, which are light dependent reactions and light independent reactions. Throughout our lab experiment, we focused on the affect access of light has on carbon dioxide during photosynthesis. Carbon dioxide levels decrease as oxygen levels increase and glucose is produced when light dependent reactions occur.…
Photosynthesis is the storage of energy in carbon compounds. In photosynthesis, the sun's energy is converted to chemical energy and stored in glucose molecules. In photosynthesis, we see energy associated with electrons or being released from association of electrons. There are two pathways associated with photosynthesis: light and dark reactions. I will concentrate on the non-cyclic light reactions of photosynthesis. Light reactions are driven by light energy. This pathway produces ATP and a reduced electron carrier (NADPH + H ). The overall reaction is solar energy + 6CO + 6H O -> C H O + 6O + heat. Where photosynthesis takes place in specific groups of organisms, cellular respiration is done by all cells. In respiration, the energy stored in organic compounds may have been produced by the cell itself or…
Photosynthesis is an anabolic process where plants produce sugars from carbon dioxide, light energy and water. The sugars are used for other anabolic reactions e.g. protein synthesis and the energy required for these reactions comes from ATP which is synthesised from chemical energy into ATP during respiration. The ATP used in plants is made from the conversion of light energy from the sun, to chemical energy by plants, into the form of organic molecules during respiration in all cells. The ATP produced can then be used by cells to perform useful work e.g.…
During photosynthesis, plants use the energy of light to produce glucose (C6H12O6) from carbon dioxide (CO2), and water (H2O). Glucose is a simple sugar that plants use for energy and as a building block for larger molecules.…

In plants, cells called chloroplasts collect energy from the sun and use water and carbon dioxide (photosynthesis) to make sugars.1 Light energy (called photons) hit single chlorophyll pigments in the cells of the plant leaves. 2 Photoautotrophs is the term used for plants that create energy out of sunlight. Plants that do not use the sun’s energy are called chemoautotrophs.3 For photosynthesis to begin a few conditions must be met; enough water must be available in a plant’s body, there should be direct sunlight on its leave, the leaves are green, and the leaves need to have access to carbon dioxide in the air.4 When the light energy has stimulated enough of the chlorophyll it is brought to a singular part of the chloroplast. The light energy combines with the water molecules, carbon dioxide molecules, and adenosine diphosphate and creates a chemical reaction.5 This chemical reaction produces oxygen and adenosine triphosphate, or ATP.6…
We can put so briefly the process saying that the organisms use the energy from sunlight to produce sugar, which cellular respiration converts into ATP, The conversion of no usuable sunlight energy into usable chemical energy, is associated with the actions of the green pigment chlorophyll. Most of the time, the photosynthetic process uses water and release the oxygen that we absolutely must have to stay alive…
