What does methylene blue do to the activity of the cell?

Methylene blue can act as a redox indicator by accepting or donating electrons in cellular processes. It may affect cell activity by interfering with electron transport chain function, disrupting mitochondrial activity, and potentially generating reactive oxygen species. Overall, its impact on cell activity depends on concentration, exposure duration, and specific cellular pathways.


Is a nucleus acidic or alkaline in a staining of cheek cells fro microscopic analysis?

The nucleus in a staining of cheek cells for microscopic analysis typically appears acidic when stained with basic dyes such as hematoxylin. This is because the basic dyes bind to the acidic components of the nucleus, resulting in a dark blue or purple color.


Why are onion cells in a sheet and cheek cells individual units?

Due to the techniques of obtaining the samples, onion cells remain intact in the tissue, but because cheek cells are obtained by rubbing a toothpick on your cheek, you are disrupting the cheek tissue, and instead of getting a sheet of cheek cells, you get individual cheek cells.


What other organelle is missing from a humans cheek cell?

Human cheek cells, like other eukaryotic cells, are missing chloroplasts, which are organelles responsible for photosynthesis in plants and some protists. Since cheek cells are part of animal tissue, they do not perform photosynthesis and therefore lack chloroplasts. Instead, they contain other organelles such as mitochondria for energy production and a nucleus for genetic material.

What are the comparison between cheek cell stained with iodine and cheek cell stained with methylene blue?

Cheek cells stained with iodine typically appear yellow-brown, highlighting the presence of starch granules if any are present, but they may not show much cellular detail. In contrast, cheek cells stained with methylene blue exhibit a more vibrant blue color, allowing for clearer visualization of cellular structures such as the nucleus and cytoplasm. Methylene blue is better for highlighting cellular morphology, while iodine is primarily used for specific staining of certain components. Overall, methylene blue provides more detail for observing cell structure compared to iodine.


What is the function methylene blue solution in the preparation of cheek cells slide?

Methylene Blue, in this situation, is being used as a microscopy stain. Microscopy stains are used to allow for particular characteristics of cells to be observed in greater detail or to make them easier to see.


What can you observe when you stain a cheek cell with methylene blue stain?

When staining a cheek cell with methylene blue, you can observe the cell's nucleus as a distinct blue color. The stain highlights the nucleus due to its affinity to bind with DNA. The rest of the cell may appear pale blue or colorless in comparison.


Is the cell surface membrane permeable to methylene blue?

Methylene blue is used to stain animal cells, such as human cheek cells, to make their nuclei more observable. Also used to staining the blood film and used in cytology. It gives a blue coloration to the human cheek cell.


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.


What equipment should be used when making slides of cheek cells to observe under a microscope?

To make slides of cheek cells for microscopy, you will need a microscope slide, cover slip, swab or toothpick to collect the cells, a staining solution (such as iodine), and a microscope with at least 400x magnification. You may also need a pipette or dropper to apply the staining solution.


Why is methylene blue necessary to view your check cells?

This is because the cheek cell is transparent. Since the membrane of the cheek cell is selectively permeable, it allows the methylene blue to enter the cell , therefore makes it blue in color from the inside. Then we are able to see the cheek cell properly under a microscope... please note. : we are supposed to add a bit of water and gliserene too . WATER : to transfer the cheek cells on to the slide AND GLISERENE: to prevent the cheek cells from drying up.


What is methylene blue use for when gram staining?

Methylene blue can be used to prepare slide for animal cells. For example, if you want to examine a piece of your cheek cell, you would take a piece of cotton wool and rub it on the inside of your cheek and the rub it on a microscope slide, the you add a little distilled water and then a drop of methylene blue. The final step you would take, is to cover the slide with a cover slip, then place it under the microscope.


Some similer thing from a cheek cell and a finger cell is?

the cheek cell is not skin and so it is not like a finger, plus the finger cell would hurt much more, cheek cells are just a scraping with a touch of Iodine.


Which type of solution would cause a cheek cell to shrink?

A hypertonic solution would cause a cheek cell to shrink. In a hypertonic solution, the concentration of solutes outside the cell is higher than inside, leading to water leaving the cell by osmosis, causing it to shrink.


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.
