FLASHCARD QUESTION

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, occurring naturally from areas of high concentration to low concentration.

FLASHCARD QUESTION

Front

What is active transport?

Back

Active transport is the movement of substances across a cell membrane that requires energy, usually against a concentration gradient.

3.

FLASHCARD QUESTION

Front

What is simple diffusion?

Back

Simple diffusion is the process by which small molecules move directly through the phospholipid bilayer of a cell membrane from an area of high concentration to an area of low concentration.

4.

FLASHCARD QUESTION

Front

What is osmosis?

Back

Osmosis is the diffusion of water molecules through a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

5.

FLASHCARD QUESTION

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the process by which larger or polar molecules pass through the cell membrane with the help of transport proteins, moving from high to low concentration without energy.

FLASHCARD QUESTION

Front

What are phospholipids?

Back

Phospholipids are molecules that make up the cell membrane, consisting of a hydrophilic (water-attracting) 'head' and two hydrophobic (water-repelling) 'tails'.

7.

FLASHCARD QUESTION

Front

How many layers of phospholipids are in the cell membrane?

Back

The cell membrane is made up of two layers of phospholipids, known as the phospholipid bilayer.
