A variegated leaf with green and yellow patches is used for an experiment to prove that chlorophyll is required for photosynthesis . Before experiment the green portion a , and pale yellow pirtion b, are observed. What will be the colour of a just before and after the starch test ? Also write the equation of photosynthesis and mark, as well as validate from which molecule the by product is obtained.

The colour of A i.e. the green portion before the starch test is pale yellow because chlorophyll needs to be removed before the starch test, and and after the test it's colour is blue-black because of the reaction of iodine and starch present in A.
The Equation of photosynthesis is :
6CO2 + 6H2O + Light energy = C6H12O6 + 6O2
The Equation of photosynthesis is :
6CO2 + 6H2O + Light energy = C6H12O6 + 6O2
