If you would be keen on discovering more regarding photosynthesis, you should try this quiz. Explain why photosynthesis is so important to energy and material flow for life on earth. Photosynthesis is the process by which plants make their food (starch or sugar). Write the events take place during photosynthesis. Photosynthesis is the process by which plants make their own food using carbon dioxide, water and sunlight. Solution: Biosynthetic phase of photosynthesis : • It occurs in the stroma of chloroplasts. Answered Explain the process of photosynthesis grade 7 … Q6. Become our. Recommendation. Photosynthesis can be explained in four simple steps, as follows. Business Enquiry (North) 8356912811. Business Enquiry (South) 8104911739. Business Enquiry (West … Photosynthesis is also in charge of balancing oxygen and carbon dioxide amounts in the atmosphere. What Is the Basic Role of CO2 in Photosynthesis? The process of photosynthesis is similar to that of C 4 plants but instead of spatial separation of initial PEPcase fixation and final Rubisco fixation of CO 2, the two steps occur in the same cells (in the stroma of mesophyll chloroplasts) but at different times, night and day, e.g., Sedum, Kalanchoe, Opuntia, Pineapple (Fig. Food, but is equally important for plants, Algae and certain bacteria that convert light energy to make from.
