Question

Leaves other than green colour perform photosynthesis. How will you test it?​

Answer 1

Answer:

Experiment to prove leaves other than green in colour also undergo photosynthesis

Take some plants, one with green leaves and other with some other colour.

As we know that plants undergoing photosynthesis have stored carbohydrates in them.

Now performing iodine test will prove that leaves other than green in colour also have stored carbohydrates which in turn will prove that leaves other than green in colour also undergo photosynthesis because iodine in presence of starch turns into blue black colour.

But if the leaf does not turn blue black on addition of iodine then it proves that the leaf belongs to a plant that does not undergo photosynthesis

Such plants containing non-green leaves but still exhibiting photosynthesis contains non-green pigments known as anthocyanins and carotenoids in addition to chlorophylls and this pigment anthocyanins are present in such large amounts that they cover up the green due to chlorophyll but the covered up chlorophyll continues to perform its function of carrying photosynthesis
