Review the structure of the chloroplast and know where the light reaction and the Calvin cycle take place. Ans:Light reactions take place in the thylakoid membrane of the granum. The Calvin cycle takes place in the stroma (cytoplasm of the chloroplast). The light reaction of photosynthesis begins when pigments in the chloroplast absorb light energy (photons). At the end of the light reaction, where is the energy derived from the photons stored? Ans:In NADPH and ATP which are then used...

What are the components of the biosphere? - Answer-Atmosphere (air), Lithosphere (land), Hydrosphere (water) Describe the atmosphere composition - Answer-Most of the atmosphere is made up of Nitrogen - 78.084% and Oxygen - 20.95%. Water makes up between 1%-4%. Describe the flow of Solar Energy through Photosynthesis - Answer-6CO2 + 6H2O + light energy ---> 602 + C6H12O6. Describe the flow of Solar Energy through Cellular Respiration - Answer-C6H12O6 + 6O2 ----> 6C02 + 6H20 + heat e...

How does the arrangement of dermal tissues and ground tissues serve the leaves which are said to be ideally suited for photosynthesis - Answer - Epidermis is thin and transparent= allow more light to reach the palisade cells - Palisade cell layer at top of leaf= To absorb more light - Spongy layer= Air spaces allow carbon dioxide to diffuse through the leaf, and increase the surface area - The flat, thin shape of a leaf, its spongy mesophyll layer and stomata are adaptations that also all...
