Cell Transport

Front

What is a hypotonic solution?

Back

A solution that has fewer solutes than the cell, causing water to move into the cell.

Front

What process requires no energy from the cell?

Back

Simple diffusion.

Front

What is facilitated diffusion?

Back

A process that allows molecules to cross membranes with the help of special proteins, requiring no energy from the cell.

Front

What is active transport?

Back

The movement of molecules against a concentration gradient, requiring energy from ATP.

Front

What happens to a cell in a hypertonic solution?

Back

Water moves out of the cell, causing it to shrink.

Front

What is an isotonic solution?

Back

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

Front

What is the role of ATP in cellular transport?

Back

ATP provides the energy required for active transport processes.

Front

What is diffusion?

Back

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

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What is the difference between passive and active transport?

Back

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