What is the purpose of heating the onion root tip cells and the acetocarmine stain?

Heating the onion root tip cells softens the cell walls and allows the acetocarmine stain to penetrate the cells. The stain then binds to the DNA in the cells, making the chromosomes visible under a microscope for easier observation and analysis in cell division studies.


Why is the root tip of an onion heated with acid?

The acid hardens the root tip so that it is less likely to break. The root tips have to be heated so that the stain is up taken and able to properly reach the chromatin ( which is dyed by the acectic orecin stain). This helps the cells to be seen more clearly under the microscope.


What differences are between the onion root tip and whitefish embryo in size of the cells?

The cells in the onion root tip are typically smaller and more uniform in size compared to the cells in a whitefish embryo. Additionally, the onion root tip cells are actively dividing, while the whitefish embryo cells are undergoing differentiation and organ development.


Does an onion root have prokaryotic cells?

No, an onion root does not have prokaryotic cells. It is a plant organism, and like all plants, it contains eukaryotic cells. Eukaryotic cells have a true nucleus and other membrane-bound organelles, unlike prokaryotic cells.


Why do you stain the onion root cells?

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.

Use of acetocarmine in onion root tip squash?

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.


What cells are in an onion tip but not the onion?

The cells in an onion tip but not the onion itself are usually actively dividing cells located at the growing tip of the onion root, known as the root cap cells. These cells help protect the delicate meristematic cells responsible for root growth and can often be found in the root zone of plants.


What is a good substiute stainfor looking at onion root tips under a microscope?

A good substitute stain for looking at onion root tips under a microscope is iodine solution. This stain will help to visualize the cells more clearly by highlighting the cell walls and starch grains present in the root tips.

Why would you not find a chloroplast in a onion root cell?

the reason you wouldn't see chloroplasts is because the onion root tip is underground where light can not reach and why would it need chloroplasts if it didn't need to produce energy form light?

What is the function of these epidermis onion cells?

The root cell's job is to gather minerals and and take it up the roots to the onion.


Do daughter cells occupy same column of cells as parent cells in onion?

Yes, daughter cells resulting from cell division in an onion root occupy the same column of cells as the parent cells. This organization helps maintain the overall structure and function of the root tissue.

Where in the onion plants are the green cells located?

The green cells in an onion plant are located in the leaves. These cells contain chlorophyll, which is responsible for photosynthesis and gives the leaves their green color.
