Onions produce the chemical irritant known as syn-propanethial-S-oxide. It stimulates the eyes' lachrymal glands so they release tears. Scientists used to blame the enzyme allinase for the instability of substances in a cut onion. Recent studies from Japan, however, proved that lachrymatory-factor synthase, (a previously undiscovered enzyme) is the culprit (Imani et al, 2002).
The sulfur compounds in ordinary onions are more concentrated and more effective at stimulating our tear glands.
Chilling onions can help reduce the release of the compound responsible for making you cry when cutting onions. It can also slow down the enzymatic reactions that cause onions to spoil, therefore extending their shelf life.
Onions do not contain chloroplasts because they do not perform photosynthesis. Instead, onions rely on obtaining nutrients from the soil to grow and sustain themselves. chloroplasts are found in plant cells that undergo photosynthesis to produce energy for the plant.
All onions are monocots.
I can't imagine a recipe asking for vegetables in a liquid measurement.
Onions dont make you cry the make your eyes watery
bc you touch urself at nite
White, yellow, and red onions are much more likely to make us cry than green onions. Onions make us tear up because of a reaction in the vegetable that occurs as we break into it, which causes the release of a chemical called lachrymatory factor, which then irritates our eyes.
Onions.
It's not just purple onions. There is a chemical inside of onions that, when you slice an onion, are released into the air. This causes a slight chemical reaction in your eyes, causing a burning sensation. To combat the burning, your eyes tear, causing you to "cry."
Coz thy are apples
onions
Trick question!! Chuck Norris can't cry, only cause eternal crying for his victims.
no , I mean who in the world like onions they smell bad. They make me cry:( :( :( :( :(
no they dont make you cry the purple onion is sweet so you dont have to chill them
That would be an onion. Onions don't cry, but the people who peel them do.
they don't cry
