Diffusion, Osmosis and Active transport

Question 1

What is active transport?

Answer 1

Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy.

Question 2

True or False: Active transport requires energy.

Answer 2

True

Question 3

What is diffusion?

Answer 3

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

Question 4

In which direction do molecules move in diffusion?

Answer 4

From an area of high concentration to an area of low concentration.

Question 5

What is osmosis?

Answer 5

Osmosis is the movement of water molecules across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Question 6

True or False: Osmosis only involves the movement of water molecules.

Answer 6

True

Question 7

What is active transport?

Answer 7

Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy.

Question 8

True or False: Active transport requires energy.

Answer 8

True

Question 9

What is diffusion?

Answer 9

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

Question 10

Answer 10

From an area of high concentration to an area of low concentration.

Question 11

What is osmosis?

Answer 11

Osmosis is the movement of water molecules across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Question 12
