What is the term for a cell membrane that only lets certain substances in and out?

Back

Semi-Selectively Permeable

Front

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

Back

Osmosis

Front

What type of transport requires energy to move substances against their concentration gradient?

Back

Active Transport

Front

What is the main difference between passive transport and active transport?

Back

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

Front

What is diffusion?

Back

The movement of particles from an area of high concentration to an area of low concentration.

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What is a selectively permeable membrane?

Back

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

Front

What is the role of phospholipids in the cell membrane?

Back

They form the bilayer that makes up the cell membrane, providing structure and fluidity.
