Amoeba Breathing |

 Gaseous exchange. Because amoeba is so small, the surface area of its cell membrane is very large compared with the small volume of its cytoplasm. The demands of the respiratory processes in the cytoplasm can therefore be met by simple diffusion of carbon dioxide between the cytoplasm and the surrounding water. Oxygen diffuses in and carbon dioxide diffuses out. © Copyright D G Mackean |
