write the mechanism of photosynthesis class 10

(ii) Quantum requirement in photosynthesis = 8, i.e., 8 quanta of light are required to evolve one mol. 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. Light energy is absorbed by chlorophyll molecules and is utilized for splitting water molecules into hydrogen and oxygen. The translocation takes place in the sieve tubes with the help of adjacent companion cells. The transport of soluble products of photosynthesis is called translocation. Light reaction is the first stage of photosynthesis process in which solar energy is converted into chemical energy in the form of ATP and NADPH. Mechanism of photosynthesis Report ; Posted by Dr. Jasmine Kaur 10 months, 2 weeks ago. Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. The total carbon dioxide available to plants for photosynthesis is about 11.2 x 10 14 tonnes. (ii) To remove all starch from the leaves of the plant. The process of photosynthesis occurs in two phases – the light reactions and the dark reactions.. Light reactions – As the name suggests, this reaction takes place in the presence of light. The process of light reaction is given below- CBSE > Class 10 > Science 2 answers; Dr. Jasmine Kaur 10 months, 2 weeks ago. (iii) Hence quantum yield = 1 /8 = 0.125 (i.e., a fraction of 1) as 12%. CO2, water, light, and chlorophyll are the raw materials for photosynthesis. Best Answer. For any plant performing photosynthesis, four factors influence this process. (iii) (1) To kill the cells. Answer of Write the Mechanism of Photosynthesis. The other three factors do not play a critical role in it. Out of this only 2.2 x 10 13 tonnes are present in the atmosphere @ 0.03%. of O 2. The substances are transported to the storage organs of roots, fruits and seeds. Magnitude of Photosynthesis: Only 0.2% of light energy falling on earth is utilized by photosynthetic organisms. Report ; Phloem transports soluble products of photosynthesis, amino acids, and other substances. Students (upto class 10+2) preparing for All Government Exams, CBSE Board Exam, ICSE Board Exam, State Board Exam, JEE (Mains+Advance) and NEET can ask questions from any subject and get quick answers by subject teachers/ experts/mentors/students. Answer: (i) That light is necessary for photosynthesis. In this page, you can find CBSE Class 10 Science Chapter 6 Extra Questions and Answers Life Processes Pdf free download, NCERT Extra Questions for Class 10 Science will make your practice complete. But, in case of light dependent reaction or light reaction of photosynthesis, it is most influenced by presence or absence of light. Emerson effect and Red drop: R. Emerson and C.M.
