How do unicellular organisms exchange gases with the environment?
Answers
Unicellular organisms exchange gases with the environment using a method called diffusion. Since their oxygen requirement is less, they can exchange gases through their skin using simple diffusion.
Answer:
Explanation:
The exchange of the gases take place through the process of diffusion in the unicellular organisms through the cell membrane.
Diffusion as we know is process of movement of the particles from higher concentration to the lower.
When the unicellular organisms need gases for any processes they take it from the environment through the same Diffusion of Gases process.
So if a unicellular organisms needs to give out any unneeded or any waste which is in the gas form..it uses the diffusion process. The higher concentration of that very gas will be higher compared to that of external environment. So the gas moves out of the cell body through the cell membrane.
Other than exchange of gases, the unicellular organisms uses diffusion for many other exchanges, movement, respiration etc.
Higher organisms have special organ system for this activity.
