1. CO2 and H2O are the reactants of b) Photosynthesis
Photosynthesis is fundamental to life where the solar energy is converted to biochemical energy by storing the energy in form of chemical bonds. In this process carbondioxide is fixed and water is utilised for the reaction. The chemical equation of photosynthesis is as follows:
In the light reaction of Photosynthesis, the trapped light energy by chlorophyll is used to split the hydrogen and oxygen in water called photolysis. In the dark reaction of photosynthesis, the oxygen is released into atmosphere and the hydrogen reacts with carbon and oxygen of carbondioxide to form carbohydrate that is glucose.
2. Leaves appear green because a) Chlorophyll reflects green light.
Chlorophyll is the light harvesting molecule/ pigment in the thylakoid membrane of the chloroplast. Chlorophyll has a porphyrin ring and a hydrocarbon side chain. The porphyrin ring absorbs light energy of in the wavelength of visible light where maximum photosynthesis takes place in red light of VIBGYOR light and also blue light to a much extent. The green light is not absorbed by the chlorophyll and is reflected by the chlorophyll and hence leaves appear green.
