Cell Transport

Front

What are the two types of cell transport?

Back

Passive and Active

Front

What is the process called when cells surround and engulf substances that are too big to enter the cell?

Back

Endocytosis

Front

What describes a hypotonic environment?

Back

Too much water in the cell will cause the cell to burst - the percentage of water is higher outside the cell than inside the cell.

Front

If a cell is placed in an environment with more oxygen outside the cell than inside, what will happen to the cell?

Back

The cell will gain oxygen.

Front

What is the movement of materials that requires energy called?

Back

Active transport.

Front

What is passive transport?

Back

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

Front

What is facilitated diffusion?

Back

A type of passive transport that uses transport proteins to move molecules across the membrane.

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What happens to a cell in a hypertonic solution?

Back

The cell will lose water and shrink.

Front

What is the role of transport proteins in active transport?

Back

They help move substances against their concentration gradient using energy.
