Photosynthesis is a process by which organisms like plants, algae and several types of bacteria are able to convert carbon dioxide to sugars with sunlight as the source of power. Another essential compound necessary for photosynthesis to occur is water. The carbon dioxide used in photosynthesis is taken from the atmosphere; the waste product generated during photosynthesis is oxygen which is released into the atmosphere.
The process of photosynthesis is essential for life to exist. All creatures that are not capable of carrying out photosynthesis use the sugars produced during photosynthesis as their energy source.
Of the given alternatives, the product of photosynthesis is sugar or option a.
Photosynthesis is a process by which green plants manufacture food in the presence of sunlight by the help of chlorophyll. Carbondioxide and water are taken in to make glucose and energy Oxygen is released as a biproduct.
6CO2 + 6H20 (chlorophyll/sunlight) = C6H12O6(glucose/sugar) + 12O2 + ENERGY
The answer is option i.e sugar as it is being formed as a product according to the equation. Carbondioxide is also there but as a reactant, not as a product.
