The chloroplast of mesophyll cells are normal. Photosynthesis is essential as it not only is the primary source of food for living entities but it also releases oxygen into the atmosphere which is required to breathe. Algae, protists … (3). This results in the formation of AMP (adenosine monophosphate) instead of ADP (adenosine diphosphate). ‘Photo’ means light and ‘Synthesis’ means to make. Answer:   At a very high oxygen concentration, the rate of photosynthesis begins to decline in all the plants. Thus, it seems to be a wasteful process. your funny XD. (c) the rate of photosynthesis equals the rate of respiration, Answer: (c) the rate of photosynthesis equals the rate of respiration. This phenomenon is called “Warburg effect.” Increase in the concentration of oxygen inhibits the fixation of carbon dioxide by RuBisCO. To Study What is photosynthesis? Goes through photosystem II. Oxygen is also released through the stomata. Can these be passed on to the progeny? 8. 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. You can also find What is photosynthesis? Malic acid is transported to bundle sheath cells, where it is decarboxylated by NADP and specific malic enzyme to produce pyruvic acid and carbon dioxide. Photorespiration takes place only in the presence of light whereas respiration continues both in dark and light. Hence, in C4 plants, chloroplasts are dimorphic in nature. Free photosynthesis process review. Biology Short Answer Practice Questions Photosynthesis Author: learncabg.ctsnet.org-Dennis Eichmann-2020-12-07-16-34-10 Subject: Biology Short Answer Practice Questions Photosynthesis Keywords: biology,short,answer,practice,questions,photosynthesis Created Date: 12/7/2020 4:34:10 PM C4 leaves are characterized by the presence of tightly packed, thick-walled bundle sheath cells all around the vascular bundle (Kranz anatomy). c. Name the metabolic processes taking place in the places marked (1) and (2). 2. C4 leaves are characterized by the presence of tightly packed, thick-walled bundle sheath cells all around the vascular bundle. Oxaloacetic acid is reduced by NADPH2 to form malic acid in the presence of enzyme, malate dehydrogenase. Roots aren't exposed to light, so there's no point for a plant to put chlorophyll in them. Which one of the following is the main product of photorespiration in C3 plants? 9. Levels of carbon dioxide (a reactant) will fall, and levels of oxygen (a product) will rise. perfect preparation. In short, our Sun God (Suraj Devta) has given us this life through Photosynthesis. d.oesophagus is the other name of food pipe. If the concentration of NADP+ is low, then FRS instead of transferring its electron to Fd, transfers electron to cytochrome b. 4. 4. Biology, 14.08.2020 21:07, mohit81281 What is photosynthesis Very short answer type. (ii)Water: Plants absorb water from soil through roots and transport to leaves. Flowers serve a reproductive purpose, so again, there's no reason for plants to use them for photosynthesis. e.oral rehydrating solution is the full form of ORS. of What is photosynthesis? Answers.
