Iodine stain is commonly used to detect amyloplasts due to their ability to stain starch granules purple-black.
Iodine is used to indicate the presence of starch. When iodine comes into contact with starch, it forms a dark blue-black complex, providing a visual indicator of the presence of starch in a biological sample.
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, 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.

Iodine and cyclooctene can undergo a substitution reaction in the presence of a Lewis acid catalyst to form iodocyclooctane. The iodine atom replaces one of the hydrogen atoms on the cyclooctene molecule, resulting in the formation of a new iodocyclooctane compound.
The organelles that can absorb iodine stain and be seen with the low power of a compound light microscope are the nucleus and the starch granules (amyloplasts). Iodine stains the nucleic acids in the nucleus and the stored starch in the amyloplasts, making them visible under the microscope.
Yes epithelial cells are stained
The balanced equation for the reaction of oleic acid (C18H34O2) and iodine (I2) is: C18H34O2 + 6I2 → C18H33I6O2 + 6HI. This equation shows that one molecule of oleic acid reacts with six molecules of iodine to form one molecule of iodine-substituted oleic acid and six molecules of hydrogen iodide. Balancing the equation ensures that the number of atoms of each element is the same on both sides of the reaction.
When iodine is mixed with cyclooctene, a color change from brown/red to colorless may occur, indicating that the iodine has reacted with the cyclooctene to form a diiodide product. This reaction involves addition of the iodine molecule across the double bond of cyclooctene.

Iodine is a diatomic molecule - I2.
Yes, astatine can react with sodium iodine solution to form sodium astatide and iodine gas. This reaction is a displacement reaction where astatine displaces iodine from the sodium iodine solution.
Iodine can react with lipid molecules by forming iodolipids, where the iodine molecule is bound to the lipid. This process is often used to detect the presence of lipids in a sample through a staining reaction called the iodine value test. This reaction helps to visualize the lipid molecules and is commonly used in food science and biochemistry.
