Answer:
B. the fresh water is hypertonic and the salt solution is hypotonic to the cells of the celery stalks.
Explanation:
A hypertonic medium is precisely one that has a higher solute concentration than another medium. This, in turn, is hypotonic compared to the former. Thus, these classifications can only be employed in the sense of comparison and not as the primary definition of the osmotic characteristic of a solution.
When a cell is placed in a hypertonic solution, that cell tends to seek osmotic balance and absorbs some of the solution's solutes becoming rigid and hard. For this reason, we can say that fresh water is hypertonic in relation to celery stem cells.
On the other hand, when the solution is hypotonic, the cell trying to reach an osmotic equilibrium loses part of its solutes to the solution, becoming soft and flabby. For this reason, we can say that saline is hypotonic for celery stem cells.
The process that regulates how water flows in and out of the cells of a plant causing the cell walls to expand or shrink and become rigid or limp is osmosis
The option that states what can be correctly deduced from the observation is option D
D. The fresh water is hypotonic and the salt solution is hypertonic to the cells of the celery stalks
The reason the above option is correct is as follows:
Hypertonicity is used to describe a salt solution that has a lager amount of dissolved particles or salt concentration than the amount found in other solutions such as in the blood or within cells. When in contact with another solution that has a different tonicity, the difference will result in the flow of water into the hypertonic solution
Isotonic solution are solutions that contain the same amount of solute
Hypotonic solution is one that contains less solute compares with another solution
The cause of the rigidity or turgor pressure of plants placed in fresh water is due osmosis, such that water enters into the plants cell from the fresh water
Therefore, when placed in an hypotonic solution such as fresh water, the celery stalks become stiff and when placed in an hypertonic solution such as the 0.15 M salt solution, the stalks become limp and soft.
Therefore, we can deduce that;
The fresh water is hypertonic and the salt solution is hypertonic to the cells of the celery stalks. Which is option D.
