Both Iodine and Methylene Blue will work - iodine is probably used more often for onion.
To stain onion root tip cells with acetocarmine, first immerse the root tip in acetocarmine solution for a few minutes to allow the stain to penetrate the cells. Then, rinse the root tip with water to remove excess stain while retaining the stained cells. Mount the root tip onto a slide with a drop of water and cover with a coverslip for observation under a microscope.
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.
The best part to use is inside the bulb structure. Using the finger nail or fine forceps one should attempt to obtain a 'one cell thick' epithelial sample (i.e. should resemble a piece of peeling human skin after sunburn). This can then be stained with iodine after mounting on a microscope slide in order to facilitate the viewing of internal cell structures
Staining the onion root cells helps to make the cell structures more visible under a microscope. Different stains can highlight specific cell components such as the nucleus or cell walls, which aids in studying their structure and function. Staining also helps in distinguishing different cell types and stages of cell division during experiments.
Eosinophils are the blood cells whose granules stain bright orange-red when using Wright's stain. This staining highlights their role in immune responses and inflammation.
Iodine solution is used to stain the cell contents in the prepared slide of onion peel. This helps highlight the cell structures and makes it easier to observe under a microscope, such as the nucleus and cytoplasm of the onion cells.
Acetocarmine is a DNA specific stain like feulgen stain, so the super coiled chromosomes during different stages of mitosis present in the Onion root tip cells can be visualized perfectly by treating with this stain.
You should use the green part of the green onion in your cooking.
You should probably use a sherry stain that way your longbow will stay with you a lot longer.
You can use an onion to remove the smell from spoiled paint. In the room or area where the bad smell is lingering, peel an onion and cut it in half. Place on a plate and leave it there for a couple of days.
It depends on the stain. If it is a water base stain then no. If it is a oil or solvent base it should be fine.
Yes, you can use onion salt in place of onion powder, but you should adjust the quantity due to the added salt content. A general guideline is to use about half the amount of onion salt as you would onion powder, and reduce any additional salt in the recipe accordingly. For example, if a recipe calls for 1 teaspoon of onion powder, use about ½ teaspoon of onion salt. Always taste and adjust to your preference.
Yes, the stain should be shaken before use to ensure proper consistency and even application.
use soap and hot water then stain remover
You should never paint a deck, the paint will peel (unless you live in a very arid climate I guess. The deck may be stained, you can put either oil or latex stain over old oil stain.
It is standard to use either Emmental or Gruyère in the onion soup, but a resembling grated cheese may replace it if need be.
Any dark stain looks good, but if you have a lighter, modern apartment you may want to go with a lighter stain.
