Question

sandeep picked up a fallen yellow leaf and taste itfor presence of starch will it turn bluish black and iodine why?

Answer 1

No it will not turn blueish black as the color of the leaf itself is demonstrating that it has no chlorophyll and secondly it's falling indicates that it has become dead, unable to perform photosynthesis.

since it doesn't have chlorophyll, it will not perform photosynthesis and hence not turn blue black as this color is only shown when the leaf has performed photosynthesis..


Hope!! u understand the answer....!!
