Photosynthesis is the process by which plants make their own food using carbon dioxide, water and sunlight. Why is the Sky Blue? Photosynthetic organisms are a possible means to generate clean-burning fuels such as hydrogen or even methane. If this process did not occur, life on the planet would not be possible.The main idea of photosynthesis and the development of the process. Test Your Knowledge - and learn some interesting things along the way. photosynthesis Their restriction to shallow marine environments suggests that photosynthesis was the primary means of organic matter production for these benthic communities. noun The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. The leftover hydrogen combines with carbon dioxide to produce carbohydrates, which the plant uses as food—as do any animals or humans who might eat the plant. The breaking of chemical bonds between the 2nd and 3rd phosphate groups provides most of the chemical energy used by a cell. In the field of biology, photosynthesis refers to the ability of plants to transform the light energy of the Sun into chemical energy. ‘Stomata are involved in two of the most important plant processes, photosynthesis and transpiration.’ Follow our simple guide for students to learn more about the process of photosynthesis, where plants use energy from the sun to make their own food. Plants absorb water in two ways: through the roots that are in contact with the soil or through the stroma in the form of water vapor. Recently, a research group at the University of Turku in Finland, tapped into the ability of green algae to produce hydrogen. Curious Answers To Simple Questions, What is photosynthesis? Photosynthesis is a metabolic process carried out by some cells of autotrophic organisms to synthesize organic substances from other inorganic ones. Therefore, in photosynthesis, there are two different stages: one that depends on light and one that is independent of it. 3) in the leaves there are small pores through which the carbon dioxide of the air enters. Throughout this process, the plants expel oxygen that is released into the atmosphere and with which life is possible in all living beings. and water – using light energy.

[ fō′tō-sĭn ′thĭ-sĭs ] The process by which green plants, algae, diatoms, and certain forms of bacteria make carbohydrates from carbon dioxide and water in the presence of chlorophyll, using energy captured from sunlight by chlorophyll, and releasing excess oxygen as a byproduct. Photosynthesis is a chemical reaction that takes place inside a plant, producing food for the plant to survive. Photosynthesis is a metabolic process carried out by some cells of autotrophic organisms to synthesize organic substances from other inorganic ones. In this sense, sunlight is captured by the chlorophyll of plants. The process of photosynthesis occurs in two steps. 2) once the water and mineral salts have been absorbed, the plants create the crude sap that circulates through woody tubes towards the leaves. External factors that influence photosynthesis include temperature, light intensity, lighting time, water shortage, and the concentration of carbon dioxide and oxygen in the air. Photosynthesis is defined as the process, utilized by green plants and photosynthetic bacteria, where electromagnetic radiation is converted into chemical energy and uses light energy to convert carbon dioxide and water into carbohydrates and oxygen. The Greek roots of photosynthesis combine to produce the basic meaning "to put together with the help of light". Build a city of skyscrapers—one synonym at a time.
