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.

Why do you stain a cell with iodine?
Iodine is used to stain cells so that they become more visible under a microscope. It helps to enhance the contrast between different cellular structures and organelles, making it easier to study and analyze them.
Why do you use iodine to stain a cell?
Iodine is used to stain cells because it binds to glycogen and starch, making them more visible under a microscope. This helps to visualize the cellular structures and identify specific components within the cell.
Why do we add iodine to the slide?
Iodine is added to the slide to enhance the contrast and visibility of certain cell structures, such as starch granules in plant cells. It reacts with specific components in the cell to produce a color change, making it easier to observe and study under a microscope.
What is the difference between lugols iodine and grams iodine?
Lugol's iodine is a mixture of elemental iodine and potassium iodide, commonly used as a disinfectant and as a supplement to support thyroid function. Gram's iodine, on the other hand, is a stain used in microbiology to differentiate between gram-positive and gram-negative bacteria based on their cell wall composition. The main difference lies in their applications and compositions.
Why you use iodine in onion?
Iodine may be added to onions to help prevent sprouting. This can extend the shelf life of the onion by inhibiting the growth of new shoots.
How did the iodine solution affect the image of the cell?
Iodine dyes cells a purple color. This enables things to be seen easier under a microscope.
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.
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.
How did the solution affect the image of the onion cell?
Iodine dyes cells a purple color. This enables things to be seen easier under a microscope.
Why iodine use in plant cell?
its help in plant cell growth.
What does iodine do to the activity inside the cell?
It stops the activity within the cell.
What are some little known facts about iodine?
Iodine is essential for the production of thyroid hormones that regulate metabolism. It can also be found in seawater and soil, which can affect the iodine content in food grown in those areas. Iodine deficiency can lead to thyroid conditions such as goiter.
What does lugol's iodine stain do to the activity of the cell?
I just did a lab in biology called "How Plant and Animal Cells Differ" and in the packet it had that question. The answer is: Lugol's iodine stain stops the activity of the cell. It kills whatever specimen it is staining.
What is it called when iodine diffuses out of a cell?
Osmosis
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.
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.
Why does lugol's iodine stain a cell?
Lugol's iodine stains a cell because it reacts with starch molecules present in the cell, forming a dark blue complex. This staining allows for visualization of starch granules in cells under a microscope.
