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.
Why did you iodine to cheek cells structures and what is darkest?
Iodine is used to stain cheek cells during microscopic examination to make the cellular structures more visible and easier to identify. The darkest structures in the cheek cells after staining with iodine would typically be the cell nuclei, which are rich in DNA and thus take up more of the iodine stain.
Is a potato an animal or plant cell?
A potato is a plant cell. It is a type of vegetable that grows beneath the ground as part of the potato plant. The cells in a potato contain cell structures typical of plant cells, such as a cell wall and chloroplasts.
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 lugol's iodine stain a cell?
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)
Does potato have nucleus?
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.
What is the colour for a plant cell's starch grains?
The colour for a plant cell's starch grains is typically blue or black when stained with iodine solution. This is due to the formation of a complex between iodine and starch, which results in the characteristic colour change.
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 structure in the cheek cells was stained the darkest?
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.
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 structures of the cells were stained the darkest?
In a cell stained sample, structures with higher nucleic acid content, such as the nucleus and nucleoli, tend to stain the darkest due to the affinity of dyes like hematoxylin to bind to DNA and RNA. Published images of stained cells often show the nucleus as the darkest stained structure under light microscopy.
When a onion cell is stained with iodine which organelles are you not able to see under a compound light microscope?
Under a compound light microscope, you would not be able to see specific organelles like the lysosomes, peroxisomes, endoplasmic reticulum, and Golgi apparatus in an onion cell stained with iodine. These organelles are typically smaller and/or transparent, making them difficult to visualize with this type of microscope.
