A stalk of celery is placed in salt water, what happens?

I think the environment would be hypertonic, but is that correct? 

Then, is the actual celery stalk hypertonic, hypotonic, or isotonic?

Will the water flow in or out of the cell?

Then, when the celery stalk is placed in the salt water it becomes limp and rubbery? But why?

Thank you for the opportunity to help you with your question!

Due to differences in salt concentration, the celery stalk will lose water to the environment through osmosis.

The environment is hypertonic

The celery stalk is hypotonic

Water will flow out of the cells of the celery stalk

The stalk becoes rubbery as a result of losing water to the environment. The cells shrink 

Please let me know if you need any clarification. I'm always happy to answer your questions.
