What else can I help you with?
Is every part of the cell equally stained?
No, different parts of the cell may take up stains differently based on their composition and function. Some parts may have a higher affinity for certain dyes, resulting in differential staining patterns that allow for the visualization of specific structures within the cell.
Why is the nucleus in the cheek cell 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.
Which stain sticks to the peptidoglycan in the cell wall of bacteria?
The stain that sticks to the peptidoglycan in the cell wall of bacteria is called crystal violet.
What organism doesn't stain on a gram stain?
Mycoplasma is an example of an organism that does not stain on a Gram stain due to its lack of a cell wall. Mycoplasma is classified as a bacterium, but its unique cell wall composition causes it to not retain the crystal violet stain in the Gram staining process.
Bacteria are divided into two groups based on how their cell walls absorb?
Bacteria are divided into two groups based on how their cell walls absorb the Gram stain. Gram-positive bacteria retain the stain due to their thick peptidoglycan cell wall, while Gram-negative bacteria do not retain the stain because of their thin peptidoglycan cell wall and an outer membrane.
Which parts of the cell stain darker than others?
The nucleus
What is the value of simple stain?
A simple stain like iodine can make cell parts show up that would otherwise be nearly invisible since they are colorless.A simple stain like iodine will reveal a cell's morphology.
What is the purpose of using a biological stain when microscopically examining cellular components?
Biological stains are used to enhance the contrast of cellular components under a microscope by highlighting specific structures or molecules. This helps in visualizing and distinguishing different parts of the cell, aiding in identification and analysis of cell structures and functions.
Why doesn't the whole cell stain with the cell-wall stain?
The whole cell doesn't stain during a cell wall stain because the dyes that are used are only attracted to the negative cell wall and only sticks it. The inside of the cell shows clear.
What structure of a bacterial cell determines which kind of biological stain it will take up?
The cell wall of gram-negative bacteria is a thin layer sandwiched between an outer cell envelope and an inner cell membrane. The gram-positive cell wall is much thicker, has no cell envelope, and contains additional substances that retain the blue stain.
Is every part of the cell equally stained?
No, different parts of the cell may take up stains differently based on their composition and function. Some parts may have a higher affinity for certain dyes, resulting in differential staining patterns that allow for the visualization of specific structures within the cell.
What two parts of the cell the cell respiration take place?
Cytoplasm and Mitocondria
Why is it not necessary for bleach to actually remove the substance that causes a stain?
Bleach removes the dye from what it comes into contact with. This means that when it comes into contact with a stain, it can take the pigments out of the stain. There may be other parts of the stain still there, but they are the same color as the rest of the article of clothing.
The name given to a liquid used to make cells structures easier to see?
A stain is a liquid used to make cell structures easier to see by adding color contrast. Stains can highlight specific parts of cells, making them more visible under a microscope. Different stains target different cell components or characteristics.
Why is the nucleus in the cheek cell 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 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 an azurophil?
An azurophile is a cell which has been readily stained with an azure stain.
