Summary Introduction

To analyze:

The reason why amoeba doesn't need a respiratory system.

Introduction:

Amoebas are microscopic and unicellular organisms. The body of amoeba is bounded by a very delicate membrane called plasmalemma. Respiration in amoeba takes place by a process called diffusion through plasmalemma.

Expert Solution & Answer
Check Mark

Explanation of Solution

Respiration in amoeba is aerobic and occurs through general body surface of the body by diffusion process. If the partial pressure of oxygen present in the surrounding is more than that of oxygen present in the body of amoeba, oxygen from surrounding diffuses into the body through plasmalemma and if the partial pressure of carbon dioxide in the body of amoeba is more than that of partial pressure of carbon dioxide in the surrounding, carbon dioxide diffuses out through plasmalemma into the surrounding. Since amoebas are tiny and microscopic, the rate of respiration through diffusion process is high enough to meet their metabolic needs. So amoeba does not require a respiratory system.

Conclusion

Amoebas are tiny cells. The rate of exchange gases including oxygen and carbon dioxide takes place through plasmalemma by diffusion process is enough to meet their metabolic requirements. So amoeba does not need a respiratory system.
