Draw and label a yeast cell?
yeast cells have hyphae and spore cases
Why is methylene blue used when observing cells?
Methylene blue is a stain(dye). Dyes are specific to the substance and bind only to that specific substance. Methylene blue is specific to animal cells and hence is used to observe animal cells.
Is maneval's stain an acid stain?
it is a basic dye that will stain the cells. That makes it a positive stain.
What is the result of gram stain on human cell?
Human cells have no cell walls, only a plasma membrane, and as a result lack the peptidoglycan layer that gram stains utilize to differentiate between gram negative and gram positive species of bacteria. Therefore, human cells are unable to retain the crystal violet introduced in the first step of the gram stain, and stain negative. (they appear pinkish like gram-negative bacteria)
Why are cells stained or dyed before being looked at with a light microscope?
because the dye goes into the cracks of the cells and makes it easier to see each individual one.

What is Eosin Dye?
It is a dye found in Eosin-methylene blue (EMB) agar, which permits the differentiation between enteric lactose fermenters and nonfermenters. The dye methylene blue inhibits the growth of gram positive bacteria. While the eosin acts as a pH indicator, measuring the levels of acid production due to the fermentation of lactose.Eosin is a stain that is used for staining the cells to observe the structurea nd number of cells. It is an acidophilic stain.
What is the scan that allows one to observe blood flow or metabolism in any part of the brain?
CT Scan Or MRI with dye See webMD.com For Heath and human Medical AAdvice and answers
How does Neutral red assay enters a cell?
Viable cells will take up the dye by active transport and incorporate the dye into lysosomes, whereas non-viable cells will not take up the dye. After the cells have been allowed to incorporate the dye they are briefly washed or fixed. The incorporated dye is then liberated from the cells in an acidified ethanol solution. An increase or decrease in the number of cells or their physiological state results in a concomitant change in the amount of dye incorporated by the cells in the culture. This indicates the degree of cytotoxicity caused by the test material.
What is used to dye animal cells?
Methylene Blue is the name of the dye Iodine is used for dyeing plant cells hope this helps :-)
Why do living cells appear colorless?
living cells repel the dye
What does osmosis help us to observe the cells better?
Well, from what I know, if the cell has a semi-permiable outer wall, we can find out by adding a dye to some water, then surrounding the cell with the colored water. Then you can see where, and if, it takes it in. =)
What similarities and differences did you observe when a drop of dye was added to a container?
corrosion-resistant steel
What similarities and differences did you observe when a drop of dye was added to each containers?
corrosion-resistant steel
Why is it helpful to use dye to see cells?
With most cells you can see right through them.
Do scientists believe that anything can live on Jupiter?
no because it does not have any animals if they were they will dye
What is tetrazolium dye and what is its function?
Tetrazolium dye is used in cell biology to determine which cells are viable. It is used in cancer treatment to assess the sensitivity of tumor cells to radiation.
