Iodine appears as a shiny, blue-black solid at room temperature with a distinctive metallic luster. When iodine crystals are heated, they sublimate directly from solid to gas, forming a purple vapor. In the presence of starch, iodine can form a deep blue or black complex, which is often used as a test for the presence of starch.

Which of the available stains in the onion enhanced your observations the most?
The use of iodine stain significantly enhanced my observations of the onion cells by highlighting starch granules within the cells, providing a clear contrast between the cell walls and the internal structures. This vivid staining allowed me to better visualize the cell's morphology and organization, making it easier to identify cellular components. Overall, the iodine stain proved to be the most effective in enhancing the clarity and detail of my observations.
