Cell Transport Review

Front

What are the two types of passive transport?

Back

Osmosis and diffusion.

Front

What does semi-permeable mean?

Back

To allow only some materials across the membrane.

Front

What is osmosis?

Back

The process where only water is allowed to pass through the cell membrane from a high to low concentration.

Front

What is diffusion?

Back

The movement of particles from an area of high concentration to an area of low concentration.

Front

What is endocytosis?

Back

The process by which cells engulf materials from the outside environment.

Front

What is exocytosis?

Back

The process by which cells expel materials to the outside environment.

Front

What is the main difference between passive and active transport?

Back

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

Front

What is equilibrium in the context of cell transport?

Back

A state where the concentration of substances is equal on both sides of the membrane.

Front

What role do cell membranes play in transport?

Back

Cell membranes control the movement of substances in and out of the cell.

Front

What is a concentration gradient?

Back

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