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.

What does effect iodine have on the onion cells?
Iodine is often used to stain onion cells to make the cell structures more visible under a microscope. The iodine solution will stain specific cell components such as the cell walls and starch grains, allowing for easier observation and analysis of the cells.
What is the purpose of adding iodine solution to the onion cell?
The purpose of adding iodine solution to the onion cell is to stain the cell's starch granules. Starch granules will appear blue-black when iodine solution is added, allowing for easy visualization of the presence of starch in the cell.

When you added a drop of iodine what effect did it have on the cell?
It stains the cell, making it easier to observe under microscope.
How do you look for vacuole at onion cell through light microscope?
You should use iodine to stain the cells. Set the cells on a slide, let them dry you will repeat the process until it is completely covered in iodine and then you will slide it in the stage and then hopefully you will then see the sells of the onion skins.
What does effect iodine have on the onion cells?
Iodine is often used to stain onion cells to make the cell structures more visible under a microscope. The iodine solution will stain specific cell components such as the cell walls and starch grains, allowing for easier observation and analysis of the cells.
What is the purpose of the iodine in the second slide of the onion cell?
Iodine is used as a stain to make cell structures more visible under a microscope. In the second slide of the onion cell experiment, iodine helps to stain the nucleus and other organelles within the cells, allowing for better observation and study of the cell components.
What would happen if you added three drops of iodine to an onion?
I did this experiment and after a while the onion cell became incredibly easier to see.
What is the purpose of adding iodine solution to the onion cell?
The purpose of adding iodine solution to the onion cell is to stain the cell's starch granules. Starch granules will appear blue-black when iodine solution is added, allowing for easy visualization of the presence of starch in the cell.
Why you use iodine in onion?
Iodine stains the onion so it is easier to see the cellular features, such as the nucleus, cell wall, and cytoplasm.
How did the iodine affect the image of the onion cell?
Iodine dyes cells a purple color. This enables things to be seen easier under a microscope.
Why are cells stained with iodine solution?
Cells are stained with iodine solution to visualize the presence of starch. Iodine reacts with starch to form a bluish-black complex, making it easier to visualize and distinguish starch-containing structures within the cell, such as amyloplasts or starch granules.
Why is iodine used when observing onion cells?
AnswerIodine was used to stain onion epidermal cells so you could see the cells more clearly and examine them. Naturally, the cell parts are difficult to see because they are clear.You put iodine on onion cells in order to make parts of the cell which were translucent, more visible. This is because iodine stains starch present in the onion cell.
How did the iodine solution affect the image of onion cell?
Iodine dyes cells a purple color. This enables things to be seen easier under a microscope.
Why do you use iodine solution during the preparation of slide of onion peel?
Iodine solution is used to stain the cell contents in the prepared slide of onion peel. This helps highlight the cell structures and makes it easier to observe under a microscope, such as the nucleus and cytoplasm of the onion cells.
Why do the cell walls of onions turn blue-black when put with iodine?
The blue-black color change occurs due to the reaction between iodine and starch present in the onion cell walls. When iodine comes in contact with starch, it forms a complex that absorbs light in the visible spectrum, giving the characteristic blue-black coloration.
How did the iodine soluton affect the image of the onin cell?
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.
