Solution
The correct option is B False
∙ A variegated leaf plant is taken for experiments to prove the necessity of chlorophyll for photosynthesis.
∙ Variegated leaves have green parts (where cells contain chlorophyll) and non-greenish parts (where there is no chlorophyll).
∙ Only the parts that were green become blue-black with iodine solution, showing the importance of chlorophyll in photosynthesis.
∙ At the same time, normal green leaves can also be used for the experiment, but in such cases, the entire leaf turns blue-black with iodine solution since the chlorophyll distribution is even in such cases.
