Question

A student conducted an experiment by placing a plant cell in a salt solution and the following observation is observed. What is the best explanation of the net movement of molecules? A normal plant cell is on the left. The plant cell wall is visible, and the internal structure fills the cell up to the cell wall. In the middle is an arrow pointing from left to right. On the right is a plant cell. This plant cell has a cell wall the same size as the first plant cell, and the internal structure appears to be the same. a Water is moving out of the cell at a faster rate than it is moving in. b Water is moving into the cell at a faster rate than it is moving out. c Water is moving at equal rates both in and out of the cell. d Water is neither moving in nor moving out of the cell.

Answer 1

The best explanation for this observation is that water is moving at equal rates both in and out of the cell.

Hypertonic, hypotonic and isotonic solutions

• Hypertonic solutions are solutions whose solute concentrations are greater than that of another solution for example, the internal solution of a cell place in it.

If a cell is placed in an hypertonic solution, movement of water out of the cell is greater than into the cell.

• Hypotonic solution have solute concentrations less than another solution

If a cell is placed in an hypotonic solution, movement of water into the cell is greater than out of the cell.

• Isotonic solution are solutions of equal strength to another solution.

If a cell is placed in an isotonic solution, there is an equal rate of movement of water in and out of the cell.

In the experiment conducted by the student by placing a plant cell in a salt solution, the plant cell plant cell was observed to have a normal structure to that of a normal plant cell, thus, the solution is isotonic.

Therefore, the best explanation for this observation is that water is moving at equal rates both in and out of the cell.
