Place a variegated garden croton in sunlight for a day. Test one of its leaves with iodine solution Explain what happens.

If the cell is placed in hypotonic solution, what will happen?

A healthy Croton plant bearing variegated leaves was kept in a dark cupboard to destarch it after which it was placed in sunlight for a few hours. One of the leaves was then plucked and an outline of the leaf marking the green and the non-green regions was drawn. The leaf was then tested for starch. Using the above information, answer the following questions State the aim of the above experiment.
