Cell Transport-1

Front

What happens to an animal cell in fresh water?

Back

The cell will burst because water moves into the cell due to higher solute concentration inside.

Front

What is the movement of molecules against a concentration gradient called?

Back

Active transport.

Front

In which direction do purple molecules move through a semi-permeable membrane from side A to side B?

Back

From side A to side B.

Front

What is osmosis?

Back

The movement of water across a membrane.

Front

What is true about active transport?

Back

It requires energy.

Front

Define diffusion.

Back

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

Front

What is facilitated diffusion?

Back

The process of passive transport of molecules across a membrane via specific transmembrane proteins.

Front

What is a concentration gradient?

Back

A difference in the concentration of a substance across a space.

Front

What role do cell membranes play in transport?

Back

They act as barriers that regulate the movement of substances in and out of the cell.

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy, while active transport requires energy.
