However, human activities also produce molecules like carbon monoxide and methane, both of which are also greenhouse gases. “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. Answer: Photosynthesis is a method of transforming light energy into chemical energy by phototrophs, which is later used to fuel cell functions. This time these are membranes of the thylakoid. Explain the mechanism of photosynthesis. Light reaction occurs in grana fraction of chloroplast and in this reaction are included those activities, which are dependent on light. Within the context of photosynthesis and respiration – this is mainly carbon dioxide. ← Prev Question Next Question → +1 vote . 1 Answer +1 vote . In photosynthesis, the inorganic compounds of carbon dioxide, water, and sunlight are used by photoautotrophs to produce glucose, oxygen, and water. All green parts of a plant are involved in photosynthesis. 150 views. Oxygen is also released through the stomata. Best answer. 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. Explain the access mechanism of a Magnetic disk. ; () Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. C3 Photosynthesis. Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities. explain the mechanism of photosynthesis? Photosynthesis in Plants . Assimilatory powers (ATP and NADPH 2) are mainly produced in this light reaction. - 8783528 Criminology as a science its focused on how criminal behaviors develop and interact to the environment, therefore it should utilize other science like … Explain the mechanism of photosynthesis. Chemical energy is stored in the form of sugars, which are generated from carbon dioxide and water. In xerophytes like Opuntia, the stem is green and it performs photosynthesis. Water from the stem enters into the leaves through the xylem elements of petiole, veins and veinlets. Like in respiration, in photosynthesis too, ATP synthesis is linked to development of a proton gradient across a membrane. Over half a million chloroplasts are present in one square millimetre of a leaf. Factors affecting photosynthesis Rate of photosynthesis depends on many factors like light, carbon dioxide, water and chlorophyll. [2 marks] (b) Starting with water and carbon dioxide as the raw materials, describe how a green plant produces starch molecules. The process of photosynthesis is considered as an oxidation-reduction reaction activated by light absorbed by chlorophyll or certain other substances (e.g., phycocyanin, fucoxanthol), resulting in the evolution of oxygen from water and in the formation of reduced carbon compounds (e.g., carbohydrate) from carbon dioxide. Mechanism of Opening and Closing of Stomata MECHANISM OF TRANSPIRATION Water is absorbed by the roots and is conducted upwards through the xylem vessels. The factors which influence the process of photosynthesis are light, water, CO2 and Chlorophyll of the leaf. 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. Paul Boyer introduced binding change mechanism. Events in photosynthesis Photosynthesis can be split into three basic events. Quality of the light also influences the rate of photosynthesis. Photosynthesis is very important for life on Earth. ... To explain the mechanism of ATP synthesis, binding change or flip-flop model is one of the widely accepted models. [8 marks] (c) It is found that the process of photosynthesis contributes to the balance of nature. It is an endothermic (takes in heat) chemical process that uses sunlight to turn carbon dioxide into sugars. X. ATP synthase during photosynthesis activates, as the proton ion crosses the thylakoid membrane. Explain the mechanism of photosynthesis in easy language. Bariochemical Reaction of Calvin Cycle. Explain the purpose of the chloroplast during photosynthesis? Chlorophyll absorbs the light energy from the sun to … Carbon dioxide is obtained through tiny pores in plant leaves called stomata. answered May 26, 2017 by Vikash Kumar (254k points) selected Jun 5, 2017 by Kundan kumar . Chloroplasts are the actual sites for photosynthesis. The sugars are used by the cell as energy, and to build other kinds of molecules. Photosynthesis is essentially the only mechanism of energy input in the living world. 0 Ans Explain Blackman’s law of limiting factors. Photosynthetic organisms, known as photoautotrophs, capture the energy from sunlight and use it to produce organic compounds through the process of photosynthesis. The chemiosmotic hypothesis has been put forward by Peter Mitchell (1961) to explain the mechanism. Without photosynthesis, the carbon cycle could not occur, oxygen-requiring life would not survive and plants would die. In plants, photosynthesis occurs mainly within the leaves. Photosynthesis is the process by which plants and some microorganisms make substances like carbohydrates.
