black
Iodine stains starch blue. You will be able to see the plastids where the starch is stored in the cytoplasm.
The colour for a plant cell's starch grains is typically blue or black when stained with iodine solution. This is due to the formation of a complex between iodine and starch, which results in the characteristic colour change.
It would be the color you stained.
Iodine
I stands for iodine. It is placed in group-17.

When stained with iodine and observed under a compound microscope the nucleus will stain the darkest. The cheek cell is frequently employed here as they are simple to collect and tend to take the stain easily.
The color of the chromosomes stained in a onion cell is usually a deep purple.
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
Cheek cells stained with iodine typically appear yellow-brown, highlighting the presence of starch granules if any are present, but they may not show much cellular detail. In contrast, cheek cells stained with methylene blue exhibit a more vibrant blue color, allowing for clearer visualization of cellular structures such as the nucleus and cytoplasm. Methylene blue is better for highlighting cellular morphology, while iodine is primarily used for specific staining of certain components. Overall, methylene blue provides more detail for observing cell structure compared to iodine.
Under a compound light microscope, you would not be able to see specific organelles like the lysosomes, peroxisomes, endoplasmic reticulum, and Golgi apparatus in an onion cell stained with iodine. These organelles are typically smaller and/or transparent, making them difficult to visualize with this type of microscope.
In a cell stained sample, structures with higher nucleic acid content, such as the nucleus and nucleoli, tend to stain the darkest due to the affinity of dyes like hematoxylin to bind to DNA and RNA. Published images of stained cells often show the nucleus as the darkest stained structure under light microscopy.
Tomato cells are stained with methylene blue because it binds to nucleic acids, allowing for visualization of the cell's nucleus and DNA content under a microscope. Iodine solution, on the other hand, is typically used to stain starch grains due to its ability to form a complex with starch molecules, rather than DNA.
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 iodine solution stained the onion cell by binding to starch molecules present in the cell. This caused the cell to appear darker or blue-black under a microscope, allowing for better visualization of the cell's structures like the nucleus and cell walls.
