Stentor, a genus of large protists, primarily relies on diffusion for gas exchange rather than a specialized respiratory system. Oxygen from the surrounding water diffuses through its cell membrane, while carbon dioxide diffuses out. This process is efficient due to the stentor's relatively large surface area and its aquatic environment, where oxygen is readily available. Additionally, the movement of water created by its cilia helps facilitate this exchange.
