Cell Transport

Front

What is passive transport?

Back

Passive transport is the movement of materials across the cell membrane that does not require energy from the cell.

Front

What does osmosis refer to?

Back

Osmosis is the movement of water across a membrane.

Front

What is active transport?

Back

Active transport is the movement of molecules against a concentration gradient, requiring energy.

Front

Define selective permeability.

Back

Selective permeability is the ability of the cell membrane to allow some things to pass through while preventing others.

Front

What does hydrophilic mean?

Back

Hydrophilic means 'water-loving', referring to substances that can interact with water.

Front

What is the role of concentration gradients in cell transport?

Back

Concentration gradients drive passive transport, where substances move from areas of high concentration to low concentration.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a type of passive transport that uses transport proteins to help move substances across the cell membrane.

Front

What is the difference between hydrophilic and hydrophobic?

Back

Hydrophilic substances are attracted to water, while hydrophobic substances repel water.

Front

What is the significance of the cell membrane in transport?

Back

The cell membrane regulates what enters and exits the cell, maintaining homeostasis.

Front

What is diffusion?

Back

Diffusion is the movement of molecules from an area of high concentration to an area of low concentration.
