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 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.

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.
Is iodine a hypotonic solution?
I guess that depends on what you are comparing the solution to? In comparison to human blood, it is most certainly a hypertonic solution, because there is a much higher concentration of Na+ and Cl- in the solution than in the blood. An isotonic solution would only be 0.89% NaCl. See related link for more details.
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 color is Lugol's iodine?
The color of the chromosomes stained in a onion cell is usually a deep purple.
What happens to endosperm after applying iodine solution?
Endosperm that contains starch will turn blue-black when iodine solution is applied, indicating the presence of starch in the endosperm cells. This color change occurs due to the formation of a complex between iodine and starch molecules.
How will the movement of water affect a cell if it's transferred from a hypotonic solution to a hypertonic solution?
The cell will shrink in size..
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 does iodine solution stop cytoplasmic streaming?
Iodine solution stops cytoplasmic streaming by disrupting the cytoskeleton of plant cells. Iodine is a strong oxidizing agent that can denature proteins, including those involved in cytoplasmic streaming. This disruption leads to a cessation of the movement of cytoplasm within the cell.
