Expert Answer
The light reaction of photosynthesis occurs in two main steps:

(1) Activation of chlorophyll - On exposure to light energy, chlorophyll becomes activated by absorbing photons.

(2) Splitting of water - The absorbed energy is used in splitting the water molecule into hydrogen and oxygen, releasing energy. This reaction is known as photolysis of water.

What is the Difference between end products of light reaction and dark reaction? If lime water is placed in the experimental set up for proving carbon dioxide is necessary for photosynthesis, will it work satisfactorily. Give reason. Describe the chemical changes which takes place in dark reactions. Why is the light independent phase called biosynthetic phase?
