Osmosis and diffusion

Front

What is cellular transport?

Back

Cellular transport is the movement of materials through the cell membrane.

Front

What is osmosis?

Back

Osmosis is the movement 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 diffusion?

Back

Diffusion is the process by which particles move from an area of high concentration to an area of low concentration.

Front

What does equilibrium mean in the context of cellular transport?

Back

Equilibrium refers to a state of balance where the concentration of substances is equal on both sides of a membrane.

Front

What is a selectively permeable membrane?

Back

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

What role does plasma play in the blood?

Back

Plasma surrounds red blood cells and is made up of water, salts, sugars, and other substances.

Front

What happens to red blood cells in a hypertonic solution?

What is the difference between active and passive transport?

Back

Active transport requires energy to move substances against their concentration gradient, while passive transport does not require energy.

Front

What is concentration gradient?

Back

A concentration gradient is the difference in the concentration of a substance between two areas.
