An onion cell has a rectangular shape and its size can range in length from 0.25 to 0.4 millimeters.
If you take a picture of the magnified onion cell and measure its diameter in millimeters then you can use simple maths to determine how much magnification is being applied.
It depends on the strength of the lense you are using and how high you set the magnification of the microscope.At 40X magnification, the microscope enlarges a 2 mm part of the onion and at 100X the microscope enlarges 0.8 mm of the cell. At both 40X and 100X you can online see a zoomed out image of the cells.At 400X, the microscope enlarges a 0.2 mm part of the cell. The individual cell is more clearly seen.At 1000X magnification, the microscope enlarges a 0.08 mm part of the onion cell. At this level of magnification the nucleus of the onion cell can be seen.This link shows different magnifications of the onion cells.
You can tell if an onion cell is alive by observing its turgidity and color. Live onion cells are turgid, meaning they are firm and full of water, giving them a healthy green color. Dead onion cells will appear shriveled, discolored, and lack turgidity. You can also perform a simple plasmolysis test to determine cell viability.
I regularly see onions from about 1 ounce, right up to large Walla Walla onions weighing over a pound. -Please tell me how anyone can possibly calculate what an "average onion " is. -Then I will be able to answer your question.
when my dickk is fat
Because an onion develops in the ground, and chloroplasts develop in the sunlight. Therefore no chloroplasts form. Think of it this way: Tree leaves contain chloroplasts because they contain chlorophyll in order for the leaves to turn colors. But who has ever heard of an onion changing colors because it's fall?! Onions dont need chloroplasts, so they dont have them.
You can tell if Meat is rotten if it looks brused in some spots or a brownish color.
basically sam said it was important to drink onion juice that night
An onion cell appears flat when viewed under a microscope because it is a single layer of cells arranged in a thin slice. To discern the depth of an onion cell, one would need to use techniques like differential interference contrast (DIC) microscopy or confocal microscopy, which provide depth information by creating 3D images of the cell structure.
Images have a certain amount of pixels that create the picture. If the picture seems blurry, in a way that is different than the lens being smudged or movement, then the picture has been magnified. This results because of the pixels being made larger from their actual size.
if it is crisp, juicy, and when u cut it it stings ur eyes
Yes, onions can expire. You can tell if an onion has gone bad by checking for signs of mold, soft spots, or a foul smell. If the onion looks discolored, feels mushy, or has a strong odor, it is likely spoiled and should be discarded.
