the nucleus of the onion cell.
If it is the onion, then the cells must have absorbed a large quantity of water (or some other liquid) that caused them to swell and become circular.
If there is nothing wrong with the onion then the student doesnt know how to use a microscope.The focus could be way off and the student might have set it on too high of a magnification. Also, the light level may be set too low.
Onions are a very tasty addition to many dishes, even though many people may have trouble cutting them. If the cells of an onion develops dark circles it may be a response to the nucleus of the cell.
When onion cells have large, dark circles, that could mean that they have absorbed a large amount of water or other liquid. That amount of liquid will cause the cell to swell and become circular.
The reason your are seeing dark circles is most likely that they are air bubbles. The reason your are seeing dark circles is most likely that they are air bubbles.
Air vacuoles, while examining the onion cells under microscope in temporary or prmanent preparations.
They are air vacuoles, while examining the onion cells under microscope in temporary or permanent preparations. The dark circles are the way onion skin cells differ from human cells.
Its because of Air Bubbles
more than one cell cause of the many layers.
The cell of an onion peel is a plant cell. The cells of the onion peel do not have chloroplasts because the onion bulb (white part) grows under ground and its cells do not carry out photosynthesis.
onion cells have 16 chromosomes. Which is 8 pairs
The Onion cell and cheek cell both had cytoplasm, nucleuses, and cell membranes under 400x Magnification
Osmosis takes place. The onion cell will turn flaccid due to the water loss.
Onion cells have cell walls because they are part of the kingdom plantae and they need the cell wall for support and structure.
describe onion cell
the animal cell is in the animal and the onion cell is in the onion
Yes, Onion has cell on its body
Yes, an onion is a plant and plants have cell membranes and cell walls
Typically on an onion.
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.
It is the salt solution and distilled water
more than one cell cause of the many layers.
The cell of an onion peel is a plant cell. The cells of the onion peel do not have chloroplasts because the onion bulb (white part) grows under ground and its cells do not carry out photosynthesis.
An onion cell has a large vacuole and a cell wall. Next time, ask the guru!
Bacterial cells are prokaryotic and the cells of an onion are eukaryotic.
