Which of the following processes are associated with photosynthesis? I. Energy from sunlight is absorbed   II. Carbon dioxide is evolved   III. Oxygen is given off   IV. Glucose is synthesized

Answer Details

The processes associated with photosynthesis are I, III, and IV only. During photosynthesis, energy from sunlight is absorbed by specialized pigment molecules in plant cells called chlorophyll. This energy is then used to convert carbon dioxide from the air and water from the soil into glucose, a simple sugar molecule that is used for energy and as a building block for other organic molecules. Oxygen is also produced as a by-product of this process and is released into the air. Therefore, options I, III, and IV are the correct processes associated with photosynthesis as carbon dioxide is not evolved during this process.
