Which stain you should use to stain onion peel?
To stain onion peel cells, you should use a stain called iodine. Iodine is commonly used to stain cells because it binds to starches and glycogen in the cells, making the cells more visible under a microscope.
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.
Can DAPI stain be used to visualize live cells?
No, DAPI stain cannot be used to visualize live cells as it requires fixation and permeabilization of the cells.
Why cant you use methylene blue when staining onion cells?
Methylene blue is not suitable for staining onion cells because it does not effectively bind to the distinct cell structures present in onion cells, such as the cell walls and nuclei. Toluidine blue or safranin O are commonly used stains for onion cells as they provide better contrast and visibility of cell structures.
Does Hoechst stain dead cells in a biological sample?
Yes, Hoechst stain can be used to stain dead cells in a biological sample. It is commonly used in fluorescence microscopy to distinguish between live and dead cells based on differences in their nuclear morphology.
Which stain you should use to stain onion peel?
To stain onion peel cells, you should use a stain called iodine. Iodine is commonly used to stain cells because it binds to starches and glycogen in the cells, making the cells more visible under a microscope.
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 stain is used to stain cheek cells?
methelyn blue
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.
Why is iodine used when observing onion cells?
AnswerIodine was used to stain onion epidermal cells so you could see the cells more clearly and examine them. Naturally, the cell parts are difficult to see because they are clear.You put iodine on onion cells in order to make parts of the cell which were translucent, more visible. This is because iodine stains starch present in the onion cell.
Can DAPI stain be used to visualize live cells?
No, DAPI stain cannot be used to visualize live cells as it requires fixation and permeabilization of the cells.
Do epidermal cells from petunia stain with phloroglucinol?
No, epidermal cells from petunia do not stain with phloroglucinol. Phloroglucinol is typically used to stain lignin in plant tissues, not epidermal cells. The stain mainly reacts with lignin, which is absent in the epidermal cells.
Why cant you use methylene blue when staining onion cells?
Methylene blue is not suitable for staining onion cells because it does not effectively bind to the distinct cell structures present in onion cells, such as the cell walls and nuclei. Toluidine blue or safranin O are commonly used stains for onion cells as they provide better contrast and visibility of cell structures.
Why use iodine on onion slide?
Iodine is used on onion slides to stain the cells so that the nucleus becomes more visible under a microscope. This staining technique helps enhance the contrast between the different cellular structures, making it easier to observe and study them.
Does Hoechst stain dead cells in a biological sample?
Yes, Hoechst stain can be used to stain dead cells in a biological sample. It is commonly used in fluorescence microscopy to distinguish between live and dead cells based on differences in their nuclear morphology.
The stain commonly used when preparing onion skin for viewing through a microscope is called?
Iodine solution
What is iodyene?
A stain used to observe the organelles of cells.
