Passive and Active Transport Practice

Front

What is osmosis?

Back

Osmosis is the movement of water across a membrane.

Front

What type of transport does not require energy?

Back

Passive transport does not require energy.

Front

What is endocytosis?

Back

Endocytosis is the cellular process of engulfing substances into a vesicle formed by the cell membrane.

Front

What is diffusion?

Back

Diffusion is when molecules move from a high concentration to a low concentration.

Front

Are endocytosis and exocytosis forms of passive or active transport?

Back

Endocytosis and exocytosis are forms of active transport.

Front

What is active transport?

Back

Active transport is the movement of substances against their concentration gradient, requiring energy.

Front

What is passive transport?

Back

Passive transport is the movement of substances across a membrane without the use of energy.

Front

What is exocytosis?

Back

Exocytosis is the process of releasing substances from a vesicle formed by the cell membrane.

Front

What is a concentration gradient?

Back

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

Front

What role do cell membranes play in transport?

Back

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