Question 15

Name a gas that is diffused out of cells.

Answer 15

Carbon Dioxide

Question 16

Name a gas that is diffused into cells.

Answer 16

Oxygen

Question 17

Describe how human lungs are adapted for efficient gaseous exchange.

Answer 17

Large blood supplying concentration gradients | Thin walls for faster diffusion

Question 18

Describehow surface area affects the rate of diffusion.

Answer 18

The higher the surface area the faster the rate of diffusion.

Question 19

Describe how temperature affects the rate of diffusion.

Answer 19

The higher temperature means particles have more kinetic energy and so there is a faster rate of diffusion.

Question 20

Describe how concentration the rate of diffusion.

Answer 20

The higher concentration increases the concentration gradient, so diffusion occurs faster.

Question 21

Describe how plant roots and leaves are adapted for efficient gaseous exchange.

Answer 21

Roots:Large surface area to absorb water.
