What else can I help you with?
What are two reasons why gram-positive cells may appear pink after the completion of the gram-stain?
If they were old and the cell membrane had degraded, or if you used too much decolorizer.
What thin membrane encloses the cytoplasm?
The cell membrane is the thin layer that holds cells together. Cell membranes are used as barriers and for protection.
Do gram positive stain pink?
No, gram-positive bacteria do not stain pink; they stain purple during the Gram staining procedure. This occurs because their thick peptidoglycan cell wall retains the crystal violet dye used in the staining process. In contrast, gram-negative bacteria, which have a thinner peptidoglycan layer and an outer membrane, stain pink due to the counterstain (safranin) used after the crystal violet is washed out.
Is the cell membrane and nuclear membrane the same?
yes, in terms of substances used; however, depending on where in the body the cells is positioned both the nuclear and cell membrane may differ.
What part of a cell works with a cell membrane?
well technically the whole thing because the cell membrane is used to protect the cell sorta like a force shield.
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.
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.
What are two reasons why gram-positive cells may appear pink after the completion of the gram-stain?
If they were old and the cell membrane had degraded, or if you used too much decolorizer.
What happens to the pocket in the cell in the membrane when it breaks loose from the membrane?
Usually, the membrane will burst and let its contents out into the cell membrane and get used up.
Can you gram stain a cell without a cell wall?
No, Gram staining primarily distinguishes bacteria based on their cell wall composition (Gram-positive vs Gram-negative). Cells without a cell wall, such as animal cells, cannot be Gram stained due to the absence of the target structure for the stain to bind to.
What is the cell membrane used for in the plant cell?
The Cell membrane on a plant cell is used to allow some substances into the cell (for nourishment) while keeping other (harmful or unwanted) substances out.
What thin membrane encloses the cytoplasm?
The cell membrane is the thin layer that holds cells together. Cell membranes are used as barriers and for protection.
What cell part is used to describe the outer edge of a frog blood cell?
Cell membrane
Is the cell membrane and nuclear membrane the same?
yes, in terms of substances used; however, depending on where in the body the cells is positioned both the nuclear and cell membrane may differ.
Membrane protein used to receive signals?
Receptors are proteins on the cell membrane that are used to receive signals
What part of a cell works with a cell membrane?
well technically the whole thing because the cell membrane is used to protect the cell sorta like a force shield.
Why acetone free absolute alchohol is used in leishman stain?
Acetone-free absolute alcohol is used in Leishman stain to prevent the denaturation of cellular components and ensure better stain retention. Acetone can cause precipitation of proteins and alter the staining results, whereas acetone-free alcohol provides a more stable environment for staining.
