I need a clear and concise definition of photosynthesis. From the Greek: photo, “light”, and synthesis, “putting together”. Selina Concise Biology Class 7 ICSE Solutions are given for the students so that they can get to know the answers to the questions in case they are not able to find it.It is important for all the students who are in Class 7 currently. A Dictionary of Chemistry », Subjects: It occurs in the chloroplasts (most of which are in the leaves) and there are two principal types of reactions. Breaking down photosynthesis stages. The unit of light absorbed by the chlorophyll during photosynthesis is the proton. Photosynthesis is the process by which plants and certain other organisms make glucose from carbon dioxide and water. (Oxidation refers to the removal of electrons from a molecule; reduction refers to the gain of electrons by a molecule.) Photosynthesis: Definition & Reactions. [T]he body of the work has been rendered into English with fidelity, the only change of moment being the substitution of the word "photosynthesis" for that of "assimilation." The electrons and protons produced by the photolysis of water are used to reduce NADP:2H++2e−+NADP+ → NADPH+H+. Photosynthesis definition: Photosynthesis is the way that green plants make their food using sunlight . Plants in which this form of photosynthesis occurs are referred to as C3 plants. Want to see the step-by-step answer? The light-dependent reactions. Photosynthesis, derived from the Greek words photo, meaning "light," and synthesis "putting together," is a process used by plants and some bacteria to harness the energy from sunlight to convert water and carbon dioxide to produce sugar (glucose) and oxygen. C3 cycle or C3 photosynthesis is the type of photosynthetic reaction observed in a majority of plants (80-90 percent of all plants). It occurs in the chloroplasts (most of which are in the leaves) and there are two principal types of reactions. Head of the School of Plant Biology, University of Western Australia, Crawley, Western Australia. | Meaning, pronunciation, translations and examples You could not be signed in, please check and try again. The Calvin cycle. The chemical process by which green plants synthesize organic compounds from carbon dioxide and water in the presence of sunlight. Featured here are vibrant charts illustrating the photosynthesis process, the equation of photosynthesis, precise and apt definitions of key terms in photosynthesis and activities like label the process, complete the paragraph, differentiate between light and dark reactions and much more. Photosynthesis Process and Reactions. n. [ Biol., Biochem.] This is the currently selected item. Cellular respiration. Photosynthesis review. Chemistry, View all reference entries Learn more. Photosynthesis Show Less. Photosynthesis evolution. Most plants, most algae, and cyanobacteriaperfo… See Answer. check_circle Expert Answer. Conceptual overview of light dependent reactions. The electrons released by this reaction pass along a series of electron carriers (see electron transport chain); as they do so they lose their energy, which is used to convert ADP to ATP in the process of photophosphorylation. Plants absorb carbon dioxide (CO2), more water (H20), more photons or sunlight. Instead they make their own food in a process called photosynthesis. In this lesson we'll cover the definition of photosynthesis, the equation for photosynthesis, as well as the reactants and products. Biochemistry (esp. the process by which green plants turn carbon dioxide and water into food using energy obtained from light from the sun Collocations The living world Topics Biology c1 See photosynthesis in the Oxford Advanced American Dictionary See photosynthesis in the … (False, The unit of light absorbed by the chlorophyll during photosynthesis is the photon or quantum.)
