If we destarch a leaf wouldn't there be no starch to test with and also if we kill a leaf, wouldn't there be no chlorophyll to make photosynthesis happen during the experiment?

Answer:
independent variable – the presence or absence of chlorophyll.
Dependent variable – whether starch is present or not.
Explanation:
this means that when investigating the presence of starch, it can be said that when starch is present it will react with iodine to give a black- blue colour. and it will be the via-versa.
and a leaf with chlorophyll should turn blue–black when iodine is added proving starch is present. This in turn, proves that photosynthesis occurred. The white areas of the leaf without chlorophyll could not photosynthesis. This means they could not produce glucose and turn this to starch. So, when tested with iodine, these areas should remain pale.
