What conclusions can be drawn from the Moll’s half leaf experiment [the given diagram shows the schematic representation of the experiment]?
What can be said after observing the results of the experiment?
I. Negative starch test by the leaf portion present inside the bottle indicates is necessary for this process.
II. Negative test of starch, which is also shown by the portion of the leaf present in between the split of the split cork is due to the lack of and light, thus indicating that both of them are essential requirements.
