If the iodine on/in the potato turns dark blue/purple/black, it means the iodine has reacted to the starch in the potato and has changed color.
The potato will turn blue, purple, or black as the iodine reacts to the starch in the potato.
the structures that are stained with the iodine are bean shaped organelles called leucoplasts.
The nucleus stained with iodine appears dark purple or black.
Adding Lugol's iodine to a potato slide is a common staining technique used to visualize starch granules. Lugol's iodine interacts with the starch in the potato cells, turning the granules a distinct blue-black color, making them easier to observe under a microscope. This staining process helps in identifying the presence of starch in the potato cells.
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!
Starches turn blue-black when stained with iodine (which usually stains things a reddish-brown or amber color).Iodine turns blue black when starch is present
When iodine is placed in potato juice it turns dark purple to black. It's the starch in potatoes that reacts with the iodine.
If you add iodine to a potato, the iodine will react with the starch present in the potato. This reaction will result in a color change, turning the potato a blue-black color where starch is present. This can be used as a test to detect the presence of starch in foods.
Yes epithelial cells are stained
Baked postato contains 60 mcg of iodine. However, the amount of iodine will be different if the potatoes were grown in soil that was iodine-depleted:)
iodine solution
Iodine stains starch blue. You will be able to see the plastids where the starch is stored in the cytoplasm.
