Methanol breaks down the structure of the beet membrane which in turn release the pigment, betcyanin, the pigment found in beet cell vacuoles that give beets their characteristic colour, and releases it. The more intense the colour you see, the greater damage that had been done on the membrane

Why does the crystal violent stain wash out of gram bacteria when they are decolorized in ethanol?
The crystal violet stain in Gram-positive bacteria forms a complex with the peptidoglycan layer in the cell wall, making it less permeable to decolorizer like ethanol. In Gram-negative bacteria, the outer membrane is disrupted by ethanol, allowing the crystal violet to be washed out during the decolorization step.
What a stiff layer of nonliving material that surrounds a plant cell?
Cell Wall
What structure around the outside of the plant cell keeps them from rupturing from too much water?
Cell Wall
Do nerve cells have cell walls?
No it does not have a cell wall because only plant cells have a cell wall but a nerve cell is an animal cell and an animal cell dose not have a cell wall.
What is the rigid outermost layer of the plant cell?
The cell wall surrounds plant cells.

What protects the plants cell?
cell wall
Where is the cell wall located in an animal?
There is no cell wall in a animal cell but there is a cell wall in the plant cell.
What is a outer supportive structure of a plant cell?
The cell wall is the outer supportive structure of a plant cell. It provides rigidity and support to the cell, helping the plant maintain its shape and structure. The cell wall is made up of cellulose, a complex carbohydrate that gives strength to the cell.
What does a plant cell wall and animal cell wall have in common?
An animal cell does not have a cell wall.
What is cellouse cell wall?
Cell wall made out of cellulose is the cell wall of a plant. A fungi has a cell wall composed of chitin and a bacteria has a cell wall composed of glycoprotein.
What does the cell wall do in the plant cell?
the cell wall protects the cell.
Does a human cell have a cell wall?
no a plant cell has a cell wall
What does the cell cell wall in the the plant?
the cell wall protects the cell.
Why do you use 70 percent alcohol and not 90 percent while microbial culture?
Ethanol creates pores in the cell membrane of the microbial cell by solubilizing the lipoproteins of the membrane. The activity of ethanol determines its concentration. If we 90 percent ethanol, the amount of ethanol molecules available to act upon the cell is more and it attacks the cell membrane from all sides. The dissolved lipoprotein forms a kind of layer around the cell, due to which the alcohol is unable to act further and cause damage to the cell. However, if we use 70 percent ethanol, the amount of ethanol molecules are few and it is not able to attack the cell from all sides. Thus, pores are created intermittently in the plasma membrane, the ethanol penetrates the cell and damages it completely. So, 70 percent ethanol is preferable to 90 percent when using microbial cultures.
Why isn't the cell wall needed in animal cells?
cell wall cell wall
What is a description of a cell wall?
A cell wall is the outter wall of a cell that is made of cellulose.
