explain the mechanism of photosynthesis

Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. The sugars are used by the cell as energy, and to build other kinds of molecules. Explain how air pollution may have an effect on photosynthesis and the balance of nature. The results in this study further explained how the photosynthesis reaction was decreased by these flavonoids. Authors: Muller, A Publication Date: Tue Jan 01 00:00:00 EST 1963 OSTI Identifier: 5054671 Resource Type: Journal Article Journal Name: Proc. Oxygen is also released through the stomata. ATP synthase during photosynthesis activates, as the proton ion crosses the thylakoid membrane. asked May 26, 2017 in Biology by Kundan kumar (51.1k points) life processes; Share It On Facebook Twitter Email. 150 views. “Photosynthesis Steps:” During the process of photosynthesis, carbon dioxide enters through the stomata, water is absorbed by the root hairs from the soil and is carried to the leaves through the xylem vessels. Explain the mechanism of photosynthesis. [8 marks] (c) It is found that the process of photosynthesis contributes to the balance of nature. 0 Ans Explain Blackman’s law of limiting factors. 0 Ans Give the schematic representation of photorespiration. Chemical energy is stored in the form of sugars, which are generated from carbon dioxide and water. Water from the stem enters into the leaves through the xylem elements of petiole, veins and veinlets. Photosynthesis is essentially the only mechanism of energy input in the living world. Best Answer. X. Photosynthetic organisms, known as photoautotrophs, capture the energy from sunlight and use it to produce organic compounds through the process of photosynthesis. This time these are membranes of the thylakoid. 2.85K views Ahmed asked August 14, 2017 Plant Physiology Photosynthesis. Table of Content: Light Reaction. answered May 26, 2017 by Vikash Kumar (254k points) selected Jun 5, 2017 by Kundan kumar . The model provided good simulations for rates of photosynthesis and pool sizes of intermediates under varying light, CO(2) and O(2). However, human activities also produce molecules like carbon monoxide and methane, both of which are also greenhouse gases. ← Prev Question Next Question → +1 vote . Quality of the light also influences the rate of photosynthesis. Over half a million chloroplasts are present in one square millimetre of a leaf. Share 27. a) Light: Visible spectrum of the sunlight ranges from 380 to 750 nanometres in wavelength. Water is then distributed throughout the leaves through veinlets. Mechanism of Opening and Closing of Stomata MECHANISM OF TRANSPIRATION Water is absorbed by the roots and is conducted upwards through the xylem vessels. Paul Boyer introduced binding change mechanism. Sign in. Photosynthesis is very important for life on Earth. Light Reaction. (a) State the meaning of photosynthesis based on the schematic diagram. Best answer. Explain the mechanism of photosynthesis?. Bariochemical Reaction of Calvin Cycle. Algae also use photosynthesis to turn solar energy into chemical energy. The factors which influence the process of photosynthesis are light, water, CO2 and Chlorophyll of the leaf. Answer: Photosynthesis is a method of transforming light energy into chemical energy by phototrophs, which is later used to fuel cell functions. Explain the mechanism of photosynthesis. Explain the access mechanism of a Magnetic disk. Ask questions, doubts, problems and we will help you. Photosynthesis is the process by which plants and some microorganisms make substances like carbohydrates. 3.04K views Ahmed asked August 14, 2017 Plant … Roy. In xerophytes like Opuntia, the stem is green and it performs photosynthesis. In the process of photosynthesis, the carbohydrates are synthesized from CO2 & H2O in presence of sunlight & chlorophyll and O2 is released. Like in respiration, in photosynthesis too, ATP synthesis is linked to development of a proton gradient across a membrane. Factors affecting photosynthesis Rate of photosynthesis depends on many factors like light, carbon dioxide, water and chlorophyll. Explain the purpose of the chloroplast during photosynthesis? 1 Answer +1 vote . Ask questions, doubts, problems and we will help you. Explain the mechanism of photosynthesis in easy language. Quantum Yield. Events in photosynthesis Photosynthesis can be split into three basic events. How is this access mechanism different in RAID level 5? Chloroplasts are the actual sites for photosynthesis. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds. In plants, photosynthesis occurs mainly within the leaves. ADVERTISEMENTS: Photosynthesis: The Process Of Photosynthesis Explained (With Diagrams)! C3 Photosynthesis. It is an endothermic (takes in heat) chemical process that uses sunlight to turn carbon dioxide into sugars. 2.70K views Ahmed asked August 14, 2017 Plant Physiology Photosynthesis. - 8783528 Criminology as a science its focused on how criminal behaviors develop and interact to the environment, therefore it should utilize other science like … In the atmosphere, many carbon-based molecules serve as greenhouse gases, which reflect heat back onto the Earth. The chemical reaction for photosynthesis is 6 CO2 + 12 H2O + light energy -> C6H12O6 + 6 CO2 + 6 H20 If the input water is labeled with a radioactive isotope of oxygen, 180, then the oxygen gas released as the reaction proceeds is also labeled with 180. Since photosynthesis requires carbon dioxide, water, and sunlight, all of these substances must be obtained by or transported to the leaves. Chlorophyll the green-coloured pigment present in plants is responsible for performing photosynthesis because it has the ability to absorb sunlight and convert it into food. Photosynthesis is important to living organisms because it is the number one source of oxygen in the atmosphere. ... To explain the mechanism of ATP synthesis, binding change or flip-flop model is one of the widely accepted models. Chlorophyll absorbs the light energy from the sun to … There is one difference though, here the proton accumulation is towards the inside of the membrane, i.e., in the lumen. Explain the effect of light and temperature on the rate of photosynthesis. Without photosynthesis, the carbon cycle could not occur, oxygen-requiring life would not survive and plants would die. Leaves are the most important organs of photosynthesis. But if the process of photosynthesis is viewed as a game, we see that a match fixing takes place between the factors of photosynthesis to produce the end product called the glucose/ starch, which gives life to the world of living organisms.
