A variegated leaf with green and yellow patches in used for an experiment to prove that chlorophyll is required for photosynthesis. Before the experiment the green portion (A) and the pale yellow portions (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.

'A' would turn blue black due to presence of chlorophyll which helped in performing photosynthesis.

'B' would not show positive starch test as photosynthesis is not performed there due to absence of chlorophyll

Answer:

‘A' would be green before the starch test, and blue-black following the starch test.

The equation of photosynthesis is:

6CO₂ + 6H₂O ----> C₆H₁₂O₆ + 6O₂

Oxygen ( O₂ ) is obtained from water ( H₂O ). The water  molecules split by sunlight resulting in the formation  of hydrogen, which is used for making glucose and oxygen (which is a by-product).
