Unicellular organisms such as amoeba and paramecium respire through their cell membrane. The cell membrane is thin and permeable to gases. They take in oxygen through the entire body surface and give out carbon dioxide. Exchange of gases takes place through the cell membrane by the process of diffusion.

Answer:
In unicellular organisms, the 'exchange of gases' takes place by the process of diffusion.
Explanation:
Unicellular organisms are usually aquatic and the surface area of their cell membranes is very large.
When the gas level in the organism is more, it releases the gas into the environment.
Amoeba is a unicellular organism.
