Nothing. The onion will get wet.
The cell will lose water and shrivel.
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.
increase
It would lose salt into the water.
It dies.
When salt is added to onion cell, the cytoplasm shrink due to plasmolysis. When water is added to onion cell, the cytoplasm expands back to its initial shape due to deplasmolysis.
Explain what would happen if a piece of seaweed from the ocean was placed in a fresh water aquarium?
The onion is sprouting or trying to grow, if it were placed in the soil it would develop roots as well
die..and its body will float on the surface
When a red onion cell is placed in a sucrose solution, water from inside the cell will move out due to osmosis. This will cause the cell to shrink and lose its turgidity as water moves from an area of higher concentration to lower concentration (from inside the cell to the solution outside).
There are certain types of perch that live in salt water, so in that case nothing would happen. However, if a fresh water perch was placed in salt water it would die. There are very few fish that can go between salt water and fresh water and perch is not one of them.
it cause it to swell
