Question

Anaya took a few stalks of celery and immersed them in solution X. After 10 minutes she stalks became swollen. Similarily she immersed some celery stalks in solution Y. Which after 10 minutes became shrunken. What can you deduce from this observation ?

• A. Solution X is hypotonic. while solution Y is hypertonic for celery stalks.
• B. Solution X is hypertonic. while solution Y is hypotonic for celery stalks.
• C. Solution X is isotonic. while solution Y is hypertonic for celery stalks.
• D. Solution X is hypotonic . while solution Y is isotonic for celery stalks.

Answer 1

The correct option is A Solution X is hypotonic. while solution Y is hypertonic for celery stalks.

Hypertonic solution
A solution having higher osmotic pressure than some other solution is said to be called hypertonic solution.
Hypotonic solution
A solution having a lower osmotic pressure relative to some other solution is called hypotonic solution.
So, solution $X$ is hypotonic. while solution $Y$ is hypertonic for celery stalks.
