Solution
The correct options are
A Respiration
C Photosynthesis
D Excretion
Diffusion plays an important role in the life of all living organisms. It plays a key role in the uptake and expulsion of substances between the organism and environment. Exchange of gases during respiration between our body cells and the lung alveoli is such an example. In plants, the exchange of oxygen and carbon dioxide between the leaves and the environment during the process of photosynthesis is also an example. The removal of toxic wastes into nephrons, excretory organs takes place through diffusion as well.
