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.
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!
black
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
Yes epithelial cells are stained
When iodine is placed in potato juice it turns dark purple to black. It's the starch in potatoes that reacts with the iodine.
the color of the potato will become dark blue
Presence of starch.
do not know
The effect of replacing iodine with other oxidizing agents is that the substance being stained will not be stained. Iodine is the only oxidizing agent to dye the material.
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:)
