Hii dear here is your answer.
Presence of starch in leaves can be tested by iodine test. Iodine solution turns starch blue-black. The leaf to be tested is put in a test tube containing ethyl alcohol. It is heated gently in a water bath until alcohol begins to boil. The colourless leaf is removed from alcohol and washed thoroughly with water. Then leaf is placed in a petri-dish and few drops of iodine solution are poured over it. It the leaf becomes blue-black after pouring few drops of iodine solution over it, then it indicates the presence of starch in it.
Hope it helps.
Plz mark me the brainliest.
