What is osmosis?

Back

Osmosis is the diffusion of water molecules through a semi-permeable membrane from an area of high concentration to an area of low concentration.

Front

What happens to a cell in a hypertonic solution?

Back

In a hypertonic solution, water moves out of the cell, causing the cell to shrink.

Front

What is concentration in a solution?

Back

Concentration is the amount of a given substance contained in a solution.

Front

What is exocytosis?

Back

Exocytosis is the process of engulfing a large substance from inside the cell to move it outside of the cell, using energy.

Front

What is the difference between diffusion and osmosis?

Back

Diffusion is the movement of particles from an area of high concentration to an area of low concentration, while osmosis specifically refers to the movement of water.

Front

What is a semi-permeable membrane?

Back

A semi-permeable membrane is a barrier that allows certain substances to pass through while blocking others.

Front

What occurs when a cell is placed in distilled water?

Back

Water moves into the cell, causing it to swell.

Front

What is equilibrium in the context of solutions?

Back

Equilibrium is the state where the concentration of a substance is equal throughout a solution.

Front

What is endocytosis?

Back

Endocytosis is the process of taking in large substances into the cell by engulfing them.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the process of passive transport of molecules across a cell membrane via specific transmembrane integral proteins.
