Front

What is the difference between active transport and passive transport?

Back

Active transport requires energy, while passive transport does not.

Front

What is osmosis?

Back

The movement of water across a semipermeable membrane from an area of high water concentration to an area of low water concentration.

Front

What is diffusion?

Back

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

Front

What is the role of phospholipids in the cell membrane?

Back

They form a bilayer that acts as a barrier to protect the cell.
