    Question

    The by-product of the photosynthesis process is   __________

    1. Carbon-dioxide
    2. Oxygen
    3. Glucose
    4. Both Oxygen and Glucose

    Hint:

    • Photosynthesis is an anabolic process in which plants use carbondioxide,  water and to make food for  themselves in the presence of sunlight 
    • Chlorophyll absorbs light energy which is converted into  chemical energy of food that is glucose 
    • Oxygen released by plants is the byproduct of photosynthesis which is liberated due to oxidation of water.

    The correct answer is: Both Oxygen and Glucose

    Oxygen is the byproduct of photosynthesis
