it is used to indicate the presence of starch in a solution . A positive result will indicate a blue/black solution while its absence indicates a brown color.
is used to test for the presence of starch. Starch turns into an intense "blue-black" colour upon addition of aqueous solutions of the triiodide anion, due to the formation of an intermolecular charge-transfer complex. In the absence of starch, the brown color of the aqueous solution remains.
Chloroplasts is an important part in the process of photosynthesis in some organisms. The chloroplast absorbs the energy in sunlight and uses it to produce sugars.
