STARCH
Yes, other cellular structures such as human epithelial cells can be stained intensely by iodine. However, when examining amyloplasts, you must come to that conclusion yourself. Are any cellular structures other than amyloplasts stained intensely by iodine? What can you conclude about the location of starch in storage cells of potato? Good luck and ChaCha on!
An iodine solution turns a purplish-black if it comes into contact with the presence of a starch molecule. This reaction can take place at very minute concentrations of starch.
An iodine molecule is formed by two 'I' atoms. It implies that the molecule is symmetrical and it is non-polar.
So I actually looked this up on this site this morning for my bio quiz and couldn't find the answer,.. well I've got it now so here you go,.. Iodine is used to take a look at the amyloplasts and Methylene blue is used to highlight the nuclei.

Yes epithelial cells are stained
Iodine is a diatomic molecule - I2.

Iodine is a molecule which is made up of the only element iodine.

A mess.
It is a polar molecule.
molecule of iodine is made up of similar kind of iodine atoms .So there is no difference in the electronegativity. Hence,it forms non-polar covalent bond.
