What is the effect of iodine on onion cell?
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
Why onion cells were stained with iodine but rhubarb cells were not?
Onion cells were stained with iodine because they contain starch, which reacts with iodine to produce a blue-black color, allowing for better visualization of the cells. In contrast, rhubarb cells do not contain significant amounts of starch, so staining with iodine would not yield a noticeable color change, making it unnecessary for observation. Thus, iodine staining is used selectively based on the presence of starch in the cells being examined.
Do onion cells still have chloroplasts when they have iodine on them?
The iodine has no connection as to whether the cells have chloroplasts or not. If the cells are green, then they do have them. Adding iodine doesn't change that fact. Not all cells of the plant have chloroplasts. The ones in the soil don't so if you are working with the bulb, it doesn't have chloroplasts in the first place.
What is the effect of saltwater on onion cells?
If the concentration of salt is higher OUTSIDE the cell, then water will move from the cell to the outside (osmosis) to equilibrate the concentration gradient that you have created! Water will leave the cell, and the cell will shrink (due to the decrease in volume).
What is a good substiute stainfor looking at onion root tips under a microscope?
A good substitute stain for looking at onion root tips under a microscope is iodine solution. This stain will help to visualize the cells more clearly by highlighting the cell walls and starch grains present in the root tips.
Which stain you should use to stain onion peel?
To stain onion peel cells, you should use a stain called iodine. Iodine is commonly used to stain cells because it binds to starches and glycogen in the cells, making the cells more visible under a microscope.

What color does iodine turn a onion?
When iodine comes into contact with starch, it forms a blue-black complex. Therefore, if you were to apply iodine to a cut onion, the starch present in the onion cells would react with the iodine, turning the onion a blue-black color. This color change is a common test for the presence of starch in biological samples.
How did iodine solution affects the image of the onion cells?
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.
