What else can I help you with?
Does an onion cell have more than one nucleus?
more than one cell cause of the many layers.
What cell structure gave the onion skin cells a more rigid shape than your cheek cells?
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.
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.
Why do onion cells look so different than human cheek cells?
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.
Why do onion and elodea cells have a more definite shape than the human cheek cells?
Elodea and onion cells have more consistent shapes than human epithelial cells because they have cell walls. The human epithelial cells do not have defined cell walls.
What cell parts did you find in the onion cell but not in the cheek cells?
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.
Does an onion cell have more than one nucleus?
more than one cell cause of the many layers.
Why onion cells 5 percent salt solution hypertonic?
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.
Is there more than one nucleus in an onion cell?
Yes, an onion cell typically contains one nucleus. The nucleus is an essential organelle that contains genetic material and controls the cell's activities. Onion cells are eukaryotic, meaning they have a defined nucleus.
What would most likely happen to a onion cell of it were placed in a liquid with a concentration of solutes?
In a hypotonic environment, an onion cell will fill up with water. Hypotonic refers to a solution that has lower osmotic pressure than the solution you're comparing it to.
What cell structure gave the onion skin cells a more rigid shape than your cheek cells?
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.
What does an onion cell look like after adding a salt solution NaCl?
This depends on the nature of the NaCl solution...If it is a Hyper-tonic solution (More concentrated solution than onion cells), water will move by osmosis down it's concentration gradient, from a region of less negative water potential (high Ψ) in the onion cell, to a region of more negative water potential (low Ψ) in the solution through a selectively/partially permeable membrane;so the onion cell will be plasmolysed and will look "flaccid" (vacuole gets smaller and shrinks).The vice versa happens with a Hypo-tonic (less concentrated solution than onion cell) NaCl solution;The onion cell will then look "turgid" (has a large vacuole exerting a pressure on the cytoplasm and pushing it towards the cell's cellwall to make it "tensed".
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 would most likely happen to an onion cell if it were placed in a liquid with a high concentration of solutes?
As the "salt solution" is a hypertonic solution which has the concentration of the solute outside of the cell is higher than the inside's. That also means the concentration of the water is now smaller in the outside of the cell than the inside's, which make the water molecules diffuse from the inside of the cell to the outside, resulted in making the cell (onion cell in this case) shrunken, or smaller.
Why do onion cells look so different than human cheek cells?
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.

How can you tell that the Ameoba is not a plant?
The amoeba does not have a cell wall, it has a cell membrane, and it is considerably more mobile than a plant.
