Question

Variegated leaves do not give positive result for iodine test.

• A. False
• B. True

Answer 1

The correct option is A False

• Variegated leaves are leaves which have red, brown pigments in addition to green pigment i.e., chlorophyll.
• Red and brown pigments mask the green colour of the leaf to some extent, as a result, leaves appear colorful.
• Since these leaves can also photosynthesise, they are capable of synthesising starch.
• Since iodine test is done to test the presence of starch, variegated leaves can also give the positive result for the iodine test just like green leaves.
