Can unicellular organisms breathe using their cell?
If they're not using their cell, I'm not sure what else they would be using. There's only one cell to be used. If you're asking whether there is a "breathing mechanism" within the cell, then the answer is no. Unicellular organisms don't need an extensive respiratory system like multicellular organisms. Moreover, unicellular organisms couldn't "breathe" because no organelle supports such a thing. Instead, unicellular organisms get oxygen just through diffusion. Because unicellular organisms are small, the diffusion of oxygen into the cell is sufficient for cell respiration. In contrast, larger multicellular organisms can't obtain oxygen through diffusion alone because the oxygen couldn't "get" to every cell.
Are slugs unicellular?
