Question 3

Diffusion in organisms - plant diffusion

Answer 3

Carbon dioxide, oxygen and glucose

Question 4

In humans where does diffusion take place

Answer 4

Oxygen diffuses out of the alveolus (higher concentration) into the blood (lower concentration)
Or
Carbon dioxide diffuses out of the blood (higher concentration) into the alveolus (lower concentration)

Question 5

In plants where does diffusion take place

Answer 5

Carbon dioxide from the stomata diffuses into the leaves and finally into the cells

Question 6

What does diffusion result in

Answer 6

Equilibrium

Question 7

What is diffusion

Answer 7

The net movement of particles from an area of higher concentration to an area of lower concentration. The particles are of any substance.

Question 8

Does diffusion require energy

Answer 8

NO
