Cell Transport

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

What is diffusion?

Back

Diffusion is the process by which molecules spread from areas of high concentration to areas of low concentration until they are evenly distributed.

Front

What is a solution?

Back

A solution is a liquid mixture in which one substance (solute) is evenly dissolved within another (solvent).

Front

What does equilibrium mean in the context of cell transport?

Back

Equilibrium is reached when the molecules of one substance are spread evenly throughout another substance, resulting in no net movement.

Front

What is active transport?

Back

Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, using energy.

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, typically along the concentration gradient.

Front

What is a selectively permeable membrane?

Back

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

Front

What is the role of solute in a solution?

Back

The solute is the substance that is dissolved in a solvent to form a solution.

Front

What happens to water molecules during osmosis?

Back

Water molecules move through a selectively permeable membrane to balance solute concentrations on both sides.

Front

What is the difference between osmosis and diffusion?

Back

Osmosis specifically refers to the movement of water, while diffusion refers to the movement of any type of molecules.
