During photosynthesis, oxygen gas is liberated out into the environment and is utilized by humans, animals and other living species during the process of respiration. Structurally, a leaf comprises a petiole, epidermis and a lamina. Photosynthesis takes place in two stages, namely light-dependent reactions and light-independent reactions. Light-dependent reactions are also called light reactions and occur during the day time. 2. A short summary of this paper. (ii) Quantum requirement in photosynthesis = 8, i.e., 8 quanta of light are required to evolve one mol. There is a total of 7000 x 109 tonnes of carbon dioxide in the atmosphere and photosynthesis fixes 100 x 109 tonnes per year. Chlorophyll absorbs the sunlight. Under the light-dependent reactions, the light energy is converted to ATP and NADPH, which are used in the second phase of photosynthesis. Hence, the photosynthesis reaction is considered to be an endothermic reaction. But, there are few plants who cannot and are called heterotrophs. Heterotrophs Chlorophyll is a green pigment found in the chloroplasts of the plant cell and in the mesosomes of cyanobacteria. Light-independent reaction is also called the dark reaction or the Calvin cycle. clear. The hydrogen from water molecules and carbon dioxide absorbed from the air are used in the production of glucose. Photosynthesis – A Two Fold Process.
