Diffusion and Osmosis Review

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy. It relies on concentration gradients.

Front

What does the term 'solute' refer to?

Back

A solute is the substance that is dissolved in a solution.

Front

What is the process of diffusion?

Back

Diffusion is the movement of particles from an area of high concentration to an area of low concentration without using cellular energy.

Front

What is homeostasis in the context of cells?

Back

Homeostasis is the process by which a cell maintains a stable internal environment despite changes in external conditions.

Front

What is a solvent?

Back

A solvent is the substance in which a solute is dissolved to form a solution.

Front

What is osmosis?

Back

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

Front

What is the difference between diffusion and osmosis?

Back

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

Front

What role does the cell membrane play in homeostasis?

Back

The cell membrane controls the movement of substances in and out of the cell, helping to maintain homeostasis.

Front

What is a concentration gradient?

Back

A concentration gradient is the difference in the concentration of a substance across a space.

Front

What is meant by 'selectively permeable membrane'?

Back

A selectively permeable membrane allows certain substances to pass through while blocking others.
