A biology student looked through a microscope and observed an Elodea cell in a drop of water and illustrated it in diagram A. He added a 10% hypertonic salt solution to the slide. He then observed the cell and illustrated the change in diagram B. What caused the change in the appearance of the cell after the salt solution was added?
More water flowed into the cell than out of the cell.
More salt flowed into the cell than out of the cell.
Lass salt flowed into the cell than out of the cell.
More water flowed out of the cell than into the cell.

Answer:

There are no diagrams in this question, however, it can be answered.

More water flowed out of the cell than into the cell.

Explanation:

According to this question, a biology student added 10% hypertonic salt solution to an Elodea cell in a drop of water. The student illustrated the changes observed in diagrams A and B. Based on the principles of OSMOSIS, which is the movement of water from a region of lower solute concentration to a region of higher solute concentration, water will flow out of the cell.

Since the solution outside the Elodea cell has more solute solute/salt concentration, water will be move down the concentration gradient from the cell into the extracellular solution. Hence, more water flowed out of the cell than into the cell.
