1)
The tendency for the solvent molecules of a solution to move from a region of their higher concentration to the region of their lower concentration through a semi permeable membrane is called:
Brownian movement
Diffusion
Osmosis
Dialysis
2)
When a solution has low levels of a solute, it is considered to be:
Isotonic
Hypotonic
Hypertonic
Concentrated
3)
When the concentration of solutes outside the living cell is lower than inside the cell, then the solution is said to be;
Hypotonic
Osmotonic
Isotonic
Hypertonic
4)
The membranes that only allow specific materials to pass through them are called:
Impassable membranes
Impervious membranes
Impermeable membranes
Semi permeable membranes
5)
In osmosis, solvent molecules move towards the ____ solution: that is, toward the solution with the ____ solute concentration.
hypertonic, greater
isotonic, greater
hypertonic, lesser
hypotonic, greater
6)
To conduct an experiment on osmosis using potato osmometer, one potato is filled with 40% sugar solution and second potato is filled with 30% sugar solution. Both potatoes are immersed into beakers containing 100% water. The results are demonstrated as:
Both potatoes will gain weight.
Potato A will gain weight.
Both potatoes will lose weight.
Potato B will gain weight.
7)
A beaker is partitioned by a semi permeable membrane which contains two different concentrations of solutions (as shown in below image). Which one of the following statements best describes what will happen to this system?
Sugar will move in both directions.
Water will only move from B to A.
Water will move from A to B.
Water will not move in both directions.

Vivek is doing an experiment on osmosis using potato osmometer. He filled the potato with a 50% sugar solution. If he wants water to enter from potato to beaker, which beaker should he place it into?
