Osmosis Graph Analysis Flashcard

Front

What is osmosis?

Back

Osmosis is the movement of water molecules through a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

Define hypertonic solution.

Back

A hypertonic solution has a higher concentration of solutes compared to the inside of the cell, causing water to move out of the cell.

Front

Define hypotonic solution.

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of the cell, causing water to move into the cell.

Front

What is an isotonic solution?

Back

An isotonic solution has the same concentration of solutes as the inside of the cell, resulting in no net movement of water.

Front

What happens to a cell in a hypertonic solution?

Back

The cell will lose water and may shrink or crenate.

Front

What happens to a cell in a hypotonic solution?

Back

The cell will gain water and may swell or lyse.

Front

What is the molarity of a solution?

Back

Molarity is a measure of the concentration of solute in a solution, expressed as moles of solute per liter of solution.

Front

What is the effect of a 0.1 M sucrose solution on potato cells?

Back

In a 0.1 M sucrose solution, potato cells are in a hypotonic environment, leading to more solute inside the cells and more solvent (water) outside.

Front

What is the effect of a 0.5 M sucrose solution on potato cells?

Back

In a 0.5 M sucrose solution, potato cells are in a hypertonic environment, leading to more solvent (water) inside the cells and more solute outside.

Front

What does it mean for a cell to lyse?

Back

Lysis refers to the breaking down or bursting of a cell due to excessive water intake.
