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.
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
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.

If there are Paramecia in your field of view you probably will recognize them immediately. Often, however, students do have difficulty both finding a Paramecium, and after they have found one, making it move slowly enough so they can study it at high magnification. The trick to finding a Paramecium is to scan the entire slide quickly using the scanning lens. Then, if you do not find one, make a new slide and search again. Often, Paramecia tend to move to the edges of the coverslip, and even "escape" the coverslip at its edges. The trick to slowing the Paramecia is to mix a drop of methyl cellulose with a drop of the cell culture, as…arrow_forwardWith stomata closed, a waterproof cuticle ______. a. minimizes water loss through plant surfaces b. permits gas exchange between the plant and the air c. both a and barrow_forwardWhile gazing into an aquarium, you observe bubbles coming from anaquatic plant left.
