1. The cells of an onion skin are generally rectangular in shape and range in size from 0.25 to 0.4 millimeters in length (250-400 micrometers). A millimeter is abbreviated by mm and a micrometer by the Greek letter mu (12th letter of Greek alphabet) followed by an m:
millimeter
about 1/25th of an inch
micrometer
1/25,000th of an inch
Left: Microscopic view of an onion skin showing several rectangular cells, each with a small, spherical nucleus (red arrow). The slide was stained with a drop of yellowish-brown gram's iodine. Right: Highly magnified view of a cell from the meristematic root tip of an onion showing enlarged nucleus containing 16 chromosomes. The cell is in prophase of mitosis, with distinct chromosomes (chromosome doublets) and a disintegrating nuclear membrane.
Onion is a term used for many plants in the genus Allium. They are known by the common name "Onion is a term used for many plants in the genus Allium. They are known by the common name "onion" but, used without qualifiers, it usually refers to Allium cepa onion" but, used without qualifiers, it usually refers to Allium cepa.
Onion cells are neither plants nor animals. They are simply a component of the onion organism, which is a plant. The reason onion cells are neither plants nor animals is because they rely on the larger onion for survival and therefore cannot be described as an organism themselves.
Using iodine, which will stain the onion cell yellow so that you can see the cell under a microscope, it will have a rectangular shape with curved corners, have an obvious nucleus, and the whole cell is a light yellow (stained from the iodine).
the function of the onion cell dictates that they protect the onion from radiation so if you wear onion skin on your face when you go in to a radiation chamber you will be safe.
onion is angiospermic monocot plant belong to lilliaceace family
Just a plant cell, nothing special.
In my belly
no they have cell walls because only animal cells have cell membrains
describe onion cell
Both onion cells and nerve cells have the same look. Obviously they have both got cells in them and have nerly everything the same.
the animal cell is in the animal and the onion cell is in the onion
Onion cells, like most plant cells, have rigid cell walls which give them a regular shape. They are stacked tightly in columns and rows. Cheek cells have and irregularly shaped cell membrane. and are squished together in layers.
how do you KNOW what a cell looks like?1. look at a slide with a layer of onion on it through a microscope.2. look it up on the internet.3. look at books.
like dots
Probably because the cells are dead, and all that remain are the cell walls. The perimeter of the box is the cell wall, dead or alive.
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.
No, he does not look like a vegetable.

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".

the animal cell is in the animal and the onion cell is in the onion
Yes, Onion has cell on its body
