Question

osmosis practice
match the terms below with their correct definition.

1. osmosis

• the diffusion of water across a semipermeable membrane.

1. solvent

• a substance, such as water, that is dissolving another substance in a solution.

1. solute

• a substance, such as salt, that is dissolved in a solution.

1. isotonic

• a solution in which the concentration of solute outside the cell is equal to that inside the cell.

1. hypertonic

• a solution in which the concentration of solute outside the cell is higher than that inside the cell.

1. hypotonic

• a solution in which the concentration of solute outside the cell is lower than that inside the cell.

Explanation:

1. Osmosis is the diffusion of water across a semi - permeable membrane.
2. A solvent is a substance, such as water, that is dissolving another substance in a solution.
3. A solute is a substance, such as salt, that is dissolved in a solution.
4. A hypotonic solution has a lower concentration of solute outside the cell than inside the cell.
5. An isotonic solution has a concentration of solute outside the cell equal to that inside the cell.
6. A hypertonic solution has a higher concentration of solute outside the cell than inside the cell.

Answer:

1. Osmosis - The diffusion of water across a semi - permeable membrane.
2. Solvent - A substance, such as water, that is dissolving another substance in a solution.
3. Solute - A substance, such as salt, that is dissolved in a solution.
4. Hypotonic - A solution in which the concentration of solute outside the cell is lower than that inside the cell.
5. Isotonic - A solution in which the concentration of solute outside the cell is equal to that inside the cell.
6. Hypertonic - A solution in which the concentration of solute outside the cell is higher than that inside the cell.
