  • Process (How to do the activity)

Take two potted plants which are kept in dark room for two days , mark one of pot as A and other as Bplace beaker containing KOH solution next to the plant A and beaker containing NaHCO3 solution next to plant B. cover both the pots separately by bell jars or polythene bags, take precaution such that air does not enter the polythene bags. Place both the potted plants side by side in a well lit room for about 48hrs. Test a few leaves of both the plants for starch.
