What happens when a plant cell is put in really salty water?

Answer 1

Well, it would depend on:

the species of the plant?
if its a soil plant or aquatic plant?

well for all intent and purpose, we will say its a regular soil plant cell.
No as you must be aware. There are minerals and different types of salts that plants use to grow and mature. But If too much salt, a chemical reaction will occur and kill the leaves of the plant. So back to your question.

So, the cell would notice the difference in salinity in the surrounding water and
through osmosis try to create homeostasis. But if the water saline solution is too much for the plant cell, the cell won't survive.
But if the solution is not in a toxic saline level, the plant will survive for a while.

but you should really read this article.
it explains a bit more.

Answer 2

When a plant cell is placed in really salty water, water will move out of the cell through osmosis in an attempt to balance the concentration of salt inside and outside of the cell. This loss of water can cause the cell to shrink and become dehydrated, potentially leading to cell damage or death.
