Only 1% of the water that is taken in is used during photosynthesis and remaining is lost by transpiration. Long Answer Type Questions. Life on Earth is solar powered. It is easy to think of light as something that exists and allows living organisms, such as humans, to see, but light is a form of energy. Light-dependent phase is also known as the Hill reaction or photochemical reaction. This phase occurs in the thylakoids of the chloroplast. In a situation in which the respiration rate is greater than the photosynthesis rate, glucose consumption is higher than glucose production. You need to include mechanisms of how each process is done. reduction of co2 to carbohydrates. Therefore, C 4 plants dominate grassland floras and biomass production in the warmer climates of the tropical and subtropical regions (Edwards et al., 2010). How did you reach this answer?
