Question

Why do we immediately put the peel of onion bulb in water containing petri dish? Meritnation

Answer 1

when you expose a peel of onion bulb to air, the water tends to move out because the concentration of water is more inside the cell as compared to its surroundings. thus, plasmolysis or the shrinking of the cell membrane could occur. to prevent this, we put the eel immediately in a Petri dish containing water.
