Question

Sara placed a healthy potted plant in a dark room for 48 hours to perform an experiment on photosynthesis. She plucked one of the leaves and tested it for starch. The leaf did not turn blue-black on adding Iodine solution. (a) Name the structure.
(b) Label Gray matter and White matter.

Hint:

Boiling the leaf in alcohol removes pigments and helps in staining the starch with iodine. Without light, the plant cannot produce starch during the experiment.
