The purpose of adding iodine solution to the onion cell is to stain the cell's starch granules. Starch granules will appear blue-black when iodine solution is added, allowing for easy visualization of the presence of starch in the cell.
Iodine solution stains the starch granules in the onion cells, making them appear darker under a microscope. This helps visualize the structure and distribution of the starch granules within the cells, providing information about the cellular organization of the onion tissue.

I did this experiment and after a while the onion cell became incredibly easier to see.

Iodine stains the onion so it is easier to see the cellular features, such as the nucleus, cell wall, and cytoplasm.
Iodine solution is usually used for starch test. It colors the cell blue-black if the starch is present. Onion does not have starch. Hence it will not turn blue-black when iodine solution is added. However it does have its use in staining the cell.Similar questions:Does_onion_juice_contain_starch
