What is the process called when water moves across a selectively permeable membrane?

Back

Osmosis

Front

What is the difference between passive transport and active transport?

Back

Passive transport does not require energy, while active transport requires energy.

Front

What molecule is commonly used as an energy source in active transport?

Back

Front

What is diffusion?

Back

The movement of particles from an area of higher concentration to an area of lower concentration.

Front

What is facilitated diffusion?

Back

A process that allows substances to cross membranes with the assistance of special proteins.

Front

What is exocytosis?

Back

The process by which a cell expels materials in vesicles.

Front

What is endocytosis?

Back

The process by which a cell takes in materials by engulfing them.

Front

What is a selectively permeable membrane?

Back

A membrane that allows certain substances to pass while blocking others.
