Why is the nucleus in the cheek cell stained the darkest?
When stained with iodine and observed under a compound microscope the nucleus will stain the darkest. The cheek cell is frequently employed here as they are simple to collect and tend to take the stain easily.
Are plant nuclei are always larger than animal nu?
No, plant nuclei are not always larger than animal nuclei. The size of nuclei can vary depending on the species and cell type. In general, plant cells tend to have larger nuclei due to their larger overall cell size and the presence of multiple copies of their genome.
Is the chloroplast in onion cells larger than the nuclei?
No, the nuclei in onion cells are generally larger than the chloroplasts. Nuclei are the control center of the cell and contain genetic material, while chloroplasts are responsible for photosynthesis.
What is the difference between Wright stain and Giemsa stain?
The Wright stain is a combination of eosin and methylene blue dyes, while Giemsa stain is a mixture of eosin, methylene blue, and azure dyes. Giemsa stain is commonly used for staining blood smears to visualize parasites and bacteria, while Wright stain is used more for general cell morphology in blood and bone marrow specimens.
Differentiate a blast from a promyelocyte?
both are immature cells; the promyelocyte is dark reddish granules in the cytoplasm and more cytoplasm, less nucleus. blast have more nucleus and less cytoplasm without granules in the cytoplasm.
Which parts of the cell stain darker than others?
The nucleus
What is the granular appearing cytoplasm more apparent at the sides of a cell rather than in the middle?
because sometimes the nuclei is above the cytoplasm because the nuclei is in the middle. It can also be because the sides are where there is the most activity.
Why is the nucleus in the cheek cell stained the darkest?
When stained with iodine and observed under a compound microscope the nucleus will stain the darkest. The cheek cell is frequently employed here as they are simple to collect and tend to take the stain easily.
How do you fix jacket discolouration?
You can use a dye darker than the stain if it is one that won't come out
Why is the stain blotchy on the wood surface?
The stain is blotchy on the wood surface because the wood may have uneven absorption of the stain due to variations in the wood grain or previous finishes on the wood. This can result in some areas appearing darker or lighter than others.
Do some eukaryote cells have more than one nucleus?
Yes, some eukaryotic cells, such as fungi and certain algae, can have multiple nuclei. This is known as being multinucleate or having a coenocytic structure, where the nuclei share the same cytoplasm.
What should be added to a cell preparation to increase the contrast between nucleus and cytoplasm?
Adding a stain such as Methylene Blue while color the cell. This makes it so that not all the light passes through the cell allowing for it to be more visible. This also will stain the cytoplasm a lighter color than the nucleus so the nucleus will be very dark and obvious. -Kodie
What are hyperchromatic nuclei?
A hyperchromatic nucleus (plural, nuclei) is a nucleus that takes up more stain than expected on a slide. It can be an indication of over-active nuclear function, which may be an early indication of either cancerous changes or of a cell that is responding vigorously to damage or other stimulus.
Are prokaryote cells smaller than eukaryote cells?
Usually, prokaryotes are about 10X smaller than eukaryotic cells. Eukaryotes include plant, animals, protists, and fungi. The only kind of prokaryotes on Earth are bacteria. Bacteria have no nuclei; their DNA are scattered in their cytoplasm. Eurkaryotes have specifically defined nuclei, containing all the chromosomes of DNA.
Why is skin around anus darker?
A Caucasian newborn's anal area looks just like the rest of the skin. Over time, fecal bowel movements and expulsion of gas continue to permanently stain the skin so the area becomes darker than nearby skin. Obviously, this staining looks darker in dark skinned people.
Are plant nuclei always larger than animal nuclei?
Yes, the plant nuclei is generally bigger than the animal nuclei. In most cases, the plant cells are generally bigger than the animal cells.
Is red darker than green?
Yes red is darker than green.
