The onion cell is the same as any other cell in regard to nuclei. There is but one nucleus in an onion cell.
well, a cell has one nucleus
It is not always in the center of the cell. No more than if the endoplasmic reticulum is found there. In some cell types it is found toward the edge. It may be due to what is actually in the cell.
The eukaryotic cell's structure is more complex than the prokaryotic type. The eukaryptic cell has a "true" nucleus, for one.
A bacterial cell has no nucleus. It is prokaryotic, meaning before nucleus, whereas a plant cell has a nucleus and is eukaryotic, meaning true nucleus. Also, plant cells are often specialized whereas bacterial never are.
A cell is hypertonic when it has a greater concentration than its environment, but, when a solution is hypertonic, it has a greater concentration than the cell it is being compared to. For example, a 5% salt solution is hypertonic to an onion cell while the onion cell is hypotonic to the solution.The salt concentration of an onion cell must be less than 5% - actually its somewhere between 1.6 and 1.3 percent.This question should not be in genetics, but I don't feel like switching it.
more than one cell cause of the many layers.
The onion cells are much more rectangle shaped, than the cheek cells and the nucleus in the onion cell is much more bigger and better seen in the microscope.

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.
Onion cells are plant cells, so they have a cell wall and more angular shape (but no chloroplasts, like some plant cells, since they are not part of the photosynthesizing part of the onion plant) Human cheek cells are animal cells, so the biggest difference is that they have no cell wall and thus a rounder shape.
A cell nucleus would be smaller than a cell because a cell nucleus is inside the cell, so it has to fit inside.
because Onion is a plant. Plant cells have a large vacuole in the centre of the cell which push the surrounding organelles and the nucleus towards the periphery. On the contrary, if you observe an animal cell you will find that the nucleus is situated right at the center because the vacuole is small comparatively and does not occupy a large space at the center.
The cell wall in the onion skin cells gives them a more rigid shape compared to cheek cells, which lack a cell wall and instead have a flexible cell membrane. The cell wall provides structural support and protection for the cell, helping maintain its shape.
Nucleus is not a basic component of a cell membrane. The cell membrane consists of a phospholipid bilayer with embedded proteins, while the nucleus is a distinct organelle that contains the cell's genetic material.
If you're talking about a normal eukaryotic cell, then no, it is not possible. But if the cell is undergoing cell division, the original nucleus will formed into two nuclei in the cell at one moment of time but that is because the cell is going to split into 2 daughter cells and each daughter cell needs a nucleus.
A eukaryotic cell is a type of cell that contains a nucleus and other membrane-bound organelles. These cells are found in plants, animals, fungi, and protists, and are more complex than prokaryotic cells, which lack a nucleus and organelles. Eukaryotic cells are generally larger and more evolved than prokaryotic cells.
