Passive and Active Transport Across the Cell Membrane

Front

What is the process called when vesicles fuse with the plasma membrane and release their contents to the outside of the cell?

Back

Exocytosis

Front

Which form of transport involves the cell taking in materials by forming a vesicle?

Back

Endocytosis

Front

What type of transport requires an input of energy?

Back

Active Transport

Front

What is diffusion?

Back

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

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What is facilitated diffusion?

Back

A process where molecules pass through the cell membrane with the help of special proteins.

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 pinocytosis?

Back

A type of endocytosis where the cell engulfs liquid.

Front

What is the role of the plasma membrane?

Back

To protect the cell and regulate what enters and exits.

Front

What is a vesicle?

Back

A small membrane-bound sac that transports substances within a cell.
