Question

what will happen to cells if we will cut the onion under the running water

Answer 1

Use a sharp knife to cut the onion—you'll release less of the enzymes into the air.

Cut onions in cold water.

Cut the root last—it has a higher concentration of enzymes.

Answer 2

when you cut an onion, it releases a gas called, Propanethiol S-oxide. When mixed with certain enzymes in the onion, it creates a sulfur gas. These gases then get to your eyes and create a mild acid which irritates the eyes.But when U cut it under water it cannot release the gas
