the structures that are stained with the iodine are bean shaped organelles called leucoplasts.
they create and store energy to help the potato grow and function. It uses starch.
They don't have a fixed shape. They're really irregular.
Yes, if you slice down a small potato and put it under the Microscope you will be able to see it.

The eye
the iodine stains the cell, so we can see the structures better. the nucleus is darkest
iodine indicates polysaccharides, therefore plant cells can be stained with iodine, staining the chloroplasts- composed of starch(a polysaccharide), and the cell wall- composed of cellulose ( a polysaccharide)
4.Nucleus
Large cell structures such as the nucleus and mitochondria can be seen under the light microscope if they are properly stained. In addition, chromosomes and centromeres can be seen during cell division.
Iodine
Yes, you might just have to stain the cell with iodine. The starch in the cell might block viewage of the nucleus still. It's there though.
The cell wall.. gram stain tests for presence of a thick outer layer of peptidoglycan.
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.
The structure that is seen is the cell wall. This keeps the shape of the cell and is only found in plant cells. The organelles that can be see in a stained onion cells all depends on your microscope. Under a x400 light microscope we could see the cell wall, cell membrane, nucleus and cytoplasm,
iodine is an indicator for starch, potatoes are basically starch storage organs for potato plants. that's why they are good to eat, mmm starch!
Staining the onion epidermal cells with iodine will help in making the cells more visible when viewed under a microscope. It has no other effect on the cells.
