Cell Transport

Front

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

Back

Osmosis

Front

During osmosis, in which direction does water move?

Back

Water moves from high to low concentration.

Front

What is the term for the movement of particles from areas of high concentration to areas of low concentration?

Back

Diffusion

Front

What is the term for the diffusion of particles through the cell membrane from high to low concentration?

Back

Passive transport

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 facilitated diffusion?

Back

Facilitated diffusion is the process of transporting substances across a membrane with the help of carrier proteins.

Front

What role do channel proteins play in cell transport?

Back

Channel proteins provide a passageway for specific molecules to cross the membrane.

Front

What is the significance of the concentration gradient in diffusion?

Back

The concentration gradient drives the movement of particles from high to low concentration.

Front

What is isotonic solution in relation to cell transport?

Back

An isotonic solution has the same concentration of solutes as the cell, resulting in no net movement of water.
