Mathes Biology Cell Transport

Front

What are the two types of cell transport?

Back

Passive and Active.

Front

What is passive transport?

Back

The movement of materials across a cell membrane without the use of energy.

Front

What is active transport?

Back

The movement of materials across a cell membrane that requires energy.

Front

What happens to a cell in a hypotonic environment?

Back

The cell will take in too much water and may burst.

Front

What is a hypotonic solution?

Back

A solution where the percentage of water is higher outside the cell than inside.

Front

What happens to a cell in a hypertonic environment?

Back

The cell will lose water and may shrink.

Front

What is a hypertonic solution?

Back

A solution where the percentage of water is lower outside the cell than inside.

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What is diffusion?

Back

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

Front

What role do transport proteins play in cell transport?

Back

They assist in the movement of substances across the cell membrane.
