Passive Cell Transport

Front

What is osmosis?

Back

The diffusion of water through a semi-permeable membrane.

Front

What is the function of the vacuole in plant cells?

Back

The vacuole stores water and increases turgor pressure within the cell, helping the plant support itself.

Front

What happens when the concentration of water is equal inside and outside a cell?

Back

There will be no movement of water cells.

Front

What are the two types of cell transport?

Back

Passive and Active transport.

Front

What is selective permeability?

Back

The ability of the cell membrane to allow some things to pass through while preventing others.

Front

What is passive transport?

Back

The movement of materials across the cell membrane that does not require energy from the cell.

Front

What is active transport?

Back

The movement of materials across the cell membrane that requires energy from the cell.

Front

What is diffusion?

Back

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

Front

What is facilitated diffusion?

Back

A type of passive transport that uses transport proteins to help move substances across the cell membrane.

Front

What role do transport proteins play in cell transport?

Back

Transport proteins assist in the movement of substances across the cell membrane, especially in facilitated diffusion.
